Inquisitive Challenge. This is a great time killer that not only stimulates the brain but your wild instinctive side as well! Quite addicting and quite fun, this puzzle/game is one of the best on the market to date, don't just take my word for it look at the hundreds of other great reviews or better yet, try it out for yourself, I can guarantee you won't be disappointed! Good luck and great fun ahead if you haven't played this game, it's okay, you'll know when to strike!!

Intriguing and fun. This is an interesting game, very simple yet keeps me entertained and is challenging. There are two colored circles and a white circle. You tap the colored ones and a ripple effect starts. The goal is to make the two ripples touch the white ball at the same time. The challenge is the colors have different speeds the ripple travels at so you have to get the timing right. Fun sound effects and nice color contrasting are a plus too

Mind blowing Holistic Gaming!. After playing with this game for awhile, I found that if you don't think about it so hard your timing starts to come to you almost without thinking. Play it intuitively and it'll come first one tone then the other then, just watch the path of the intersections of the wave fronts and it's like throwing something at a target, whether it is moving or not. I enjoyed it!

A nice idea wasted. It's an old yet entertaining game mechanic... Or at least I thought it started out as one. At first it leads you to believe that it's a game of keeping rhythm and matching the right ones together, kind of an easy but satisfying time waster for those experienced in music. I would have been fine with this. However, as soon as you finish the first chapter it starts moving around the target dot, throwing out that concept and just making it a "time it by luck" game (how unforgiving it is makes that worse too). How disappointing.

Unique puzzle solving game. This is a very different "solving" type of game. You'll need timing and rhythm to help move you to the next levels. Fun and just the right amount of addicting (not too too hard to leave if you really need to, but will make you want to go on to each new level if your time allows.

Good news: Addictive. Bad news: Addictive.. Easy to learn, but still a challenge. I found myself paying attention to the rhythms created when I tapped the two dots, and noticed some rhythms won more consistently than others. This is an easy game to forget about all time and daily obligations with, hence the title of this review. Good game!

Simple and relaxing. When you need a break from running games, time limits, and combat modes, this is a well thought out puzzle game that lets you solve each level at your own pace. I usually turn the sound off to all my games, but this is a game meant to be heard. I only give it 4 because it's not as addictive as others I have. But still a worthwhile game to download.

Challenging? Yes. Relaxing? It depends.... This game requires concentration. Sure one could mindlessly tap away and hope to get lucky. However, that latter approach would, more likely than not, lead to frustration because one is unable to advance to the next puzzle/level. The stark colors and tones can be soothing. But if one has been attempting to solve a particular puzzle for quite some time, then those colors and tones become irritating reminders that you are stuck. 😝

My kind of game.. Very hypnotic and fun. I love the auditory aspect as well as the basic puzzle game play. The only thing stopping me from giving it 5 stars is that so far it isn't that difficult. I hope there are updates to increase the amount of puzzles/ scenarios. A great addition would be multiple notes and if the sound(chord) made was determined by the accuracy of the overlapping wave/notes.

Fascinating concept. Initially, I was perplexed, as this game intrigues you into learning it, rather than providing much instruction. It didn't take long to catch on, and soon I was quite taken by the brilliant simplicity of the idea, yet still quietly challenged by the unique concept. I love that it IS quiet, colorful without being garish, and something I can find peaceful and challenging at once.

Addictive, fun, and challenging. This is one of the most unique games I have ever played on any system. It takes skill, patience, and a keen sense for timing in order to get the dots' sound waves to hit the white dot at precisely the same time. I'm very impressed by the polished finish of the game. No matter what level, it was never too easy. I will very much be looking forward to more apps from this dev in the future.

Calm yet challenging. This game is challenging without being aggravating. Learning to play is quick and easy, the part that is challenging is learning a sense of timing to achieve each level's goal. Once the target starts moving, the game picks up multiple paths to achieving each level. At the same time, the game is calming and soothing to play. The linking of colors and tones is very well done and adds to the almost instinctive play style.

Feast for the Senses. All movement on your screen is smooth and satisfying. Relaxing. Sounds are like the soothing single notes of a xylophone. When you achieve the goal of each level, the two notes combine realistically to create a pleasant combined tone. Same concept with the colors you see. Each circle is a rich shade of all the familiar colors of the rainbow. When each level is complete, the colors combine realistically, as if mixed on a palette. However, when your target starts moving, you cease to be indulged. Then you have to actually WORK for your goal! Every level is worth the effort. Enjoy!

Good game but needs a tweak.. I find this game addicting, but as a low-vision player, it would be nice to have the color intensity match the tone, so low tones are darker colored and higher tones are lighter colored. Maybe that. Is more for deaf players, but it would be a little consistency. It seems like you tried to do that in the game but having it more visible would help for times someone wants to play silent mode.

Fantastically addictive!. It's all about timing. As you play you'll start to associate certain colors with certain speeds. Then when you think "ok, I got this down now", yeah, you don't. Highly addicting and really fun. Who'd have thought something so simplistic could so good? There is no timer, no points, just simply "can you time your moves and progress to the next stage?", and it gets harder and harder and you think to yourself "ok, one more time". **Would really like to see iCloud sync so I can continue playing where I left off on another device.

Very unique and intriguing game!. This game shows some great intellect! It's a great puzzler , if not the best puzzler I have played on iOS. You will get frustrated in some if the later levels, but it makes it that much more rewarding when you finally hear that sweet harmonious tone when the circles intersect with the white dot. Buy it, you won't regret it!!

Innovative and brilliant. This is put mildly. Such a simple combinations of wave patterns and synchronicity. The game while appearing less than annoying flying birds that kill pigs, black and colored rings that must interlope right at the same time and same spot. This is definitely one of the most original puzzle games ever created; quite genius actually. The app is an auto 5 stars, the game should be nominated for awards.

hey there Circadia. Honestly when it comes to puzzle games I'm very picky. Unscramble the word, spot the difference, guess the song, remember the order of something, all those are so boring and repetitive. Circadia is entertaining and offers a good challenge. I usually hate getting asked to review something or to rate an app but this one deserve it, Circadia is an amazing app, I highly recommend it to someone with likes a good puzzle game.

Couldn't sleep tonight. Got this as a pick of the week. Haven't heard anyone talking about it. Thought I'd play while drinking nighttime tea...so challenging and relaxing at the same time. Beautiful colors except I don't like the red and green dots in May. Picky I know. I love the simplicity of the instructions also. Effortlessly leads you right into the game. Got up to level 30 the first time playing it. Don't know how many levels or if it scores for how many tries or how much time but don't care just like it. Must sleep now.

Interesting concept. When one considers the enormous number of calculations one needs to do to compute the convergence of two expanding circles, each moving at a different rate, in an effort to coincide with a moving dot, the task is just amazing. That a six year old child (my granddaughter) can successfully do those mental gyrations just blows my mind. Thanx for a fun game.

Pretty good. I went on a app shopping spree the other night. I bought a few games out of the top 300 or so. I do not remember how much this one was but I paid $4.99 for a couple and I have been most pleased with this one so far. It is not the best game I have ever played on the App Store but it has kept me entertained for a little while. I do not leave many reviews but I felt my opinion should be voiced on this one. It is a simple game to figure out. The soundtrack could be better but maybe the developer will work on that.

Unique. Quite a unique game. Timing is crucial but requires combining information about both speeds and positions. Actually, I'm not so much using that information as letting the experience of the game teach me almost subconsciously how to do it, feel like I need to let it soak in and become automatic rather than trying to reason it out. In any case, the light, sound, and black background make for a rather mesmerizing experience. Wouldn't mind having a reference window which laid out the relative speeds of the different colors, as I find myself forgetting which is faster/slower.

Peaceful challenges with circles. Circadia is a simple puzzler about sensations. The object is simple--make two colored ripples hit a white dot at the same time. However, it is also about meditation. The entire display is empty except for the dots and the ripples. When someone pushes each dot, a soft bell sound resonates through the speakers. It is a peaceful game meant for people to experience every sensation. Highly recommended.

Challenging and Fun. I love this game! It's a complete challenge and it gets tougher as you continue through the game. It challenges your brain to try different ways to solve the puzzle. You won't want to quit trying to solve each one, even if it takes you 10 times before you get it right!

Elegantly simple design, challenging play. This game was recommended to me because I play Eufloria. This game is also elegantly simple in its design, and gives me a very 'zen', relaxing feeling playing it. I also feel challenged by the gameplay. Spatial awareness is not my strong suit so I enjoy getting the chance to strengthen it. The chimes are very pleasing. It is definitely a challenge for each level, and there is a nice sense of achievement when I find the solution and solve the problem.

Addictive. This game is so addictive!!! It's a brain buster too. You start with a colored sphere/circle and when you tap it, it releases a ring/band that expands in equal directions. It sounds stupid but it gets better. The objective is to get the bands of the colored spheres to intersect simultaneously over the white dot. Again stupid right? But some of the bands go at a lower speed while other go faster so you have to time it just right and as you go higher in each level the white dot starts to move so you have to time it just right. It's a puzzle and it seems so simple but it's not - the challenge of figuring out the right combination and working out the timing is what makes this a fun game and passing each level becomes addictive because you want to see what the next curve ball will be. Totally worth it and some fun sound effects too! Enjoy :-)!

Takes me away.. Sometimes I just go by feel. Sometimes I get very technical with the timing and have to conjure much patience. There's a "good things will come to those who wait" kinda zen thing going on. It's addicting, yet just a couple well played rounds are enough to satisfy that mental break you needed.

I'm a circadian. My dad and I are truly circadians. We love the game, and we hope a sequel or something like it will come out to keep us entertained. We enjoy the challenges, and like to compete on which one is the better player. I know hat once more people hear about this game it will surely be a one hit wonder.

Not easy, but not stressful. A real brain puzzler that is a true challenge. But done in such a way that there is far less frustration as you work through the levels. No annoying background music, no lives to run out of, no points to earn, and the only person you compete against is you. One of my favorite insomnia games. Helps to calm my brain down and lets me think about just one thing. Which often helps me to sleep.

Challenging yet *Relaxing*. What amazes me most about this game is how NOT stressful it is. I have a super Type A personality and I don't like not winning. I agree with others--the game is hypnotic and it doesn't stress me out when I can't get it right. Sometimes I felt disappointed by winning to quickly! The simplicity of the movements and colors and the soothing tones make this a really relaxing but fun and challenging game.

My new best friend!. This game is totally different than most games; the concept is unique, and I can appreciate the complexities that have gone into the development. This review comes from a plumber who does not normally play any games, but I have tried a few. I AM a real person, and I approved this message. Fantastic!

Not what I was expecting.... One of the few good puzzle rhythm games. It's calming and relaxing. It gets difficult enough that I just only get a few levels done in a sitting. After reading your new update info I decided to redownload because it was and will continue to be one of my all time favorite games....

Nice game - Next Step Suggestion. I enjoy this game. I like the minimalist look, the interplay of color with sound and also the challenge. Unfortunately, the game lacks functionality that I expect in games that progress through levels. Virtually all games that operate like this allow the player to leave the game and return later to the same point in the game. My suggestion for a future upgrade is too add this functionality. Then it will be a 5-star game in my opinion.

relaxing and stimulating!. This is one of the best games I've downloaded so far. It takes some actual thought for each level, and if you're a music nerd, it's also fun to guess the intervals of the notes as you play. I also love the simplicity of it. Just get it already!

Waking parts of my brain.... I wouldn't be surprised if I was told down the line sometime that playing this game regularly helps us perform our jobs better, or helps our kids do better in their math classes or something. I feel many areas of my brain lighting up as I play, I swear I do. And so simple too. As well as soothing. Best played w deep grooving house music going on by the way. :)

Very elegant. Extremely simple in concept and challenging in execution. Very relaxing and stimulating at the same time. You have two colored dots that when tapped emanate a ring that grows and grows. The object is to get the rings from the two dots to touch a white "target" dot at the same time. Sounds pretty simple, but the colored dots release the ring at different rates, and then as the levels become harder, the white target begins to move, etc. I have a feeling that I may tire of it pretty soon, but for a few minutes to kill, it is a nice distraction.

Hard to put down. It starts off seemingly simple and gets increasingly more difficult as you succeed. The kids love it and it makes them think. We played for an hour after downloading. Can't wait to see what other challenges come up. Great fog the brain.

Meditative Fun. Circadia is a massively chill, light-puzzle experience where your goal is to properly time bell-like chimes. There are no game-over or do-over screens, just a continuous progression through the levels - just keep trying until you get it right. Must he played with the sound enabled for the full experience.

Relaxing. The game does a good job of making you relax and plan the movements. Because one moves faster than the other, you have to time it so that means you will wait for. Second or two to make sure they touch at the same time. Overall, very relaxing game.

1st time player, not yet impressed. First, I like to pay for a game if it’s not too expensive, and I can try it first. $2.99 is fine. I will not play a game with ads. Next, don’t mind learning a game the hard way, e.g., no hints. Here, you get five free tries, then the game is locked. The goal of this game is to get the emanating lines of the circles to hit the dot at the same time. NOT just to get the dot within the circles. My never-will-be-heard suggestion is to have a tutorial that includes more than one circle, or give enough free tries so a person can, um, play it once?

Relaxing, bit requires some concentration. This is a pretty game with pretty simple effects, I think. It,s very easy to play, but not so easy that you get bored. There is a challenge, but not so hard that you get frustrated. You can play this game before bed and still fall asleep. The slow moving circles are relaxing, but to get the timing just right requires attention and a bit of "zen." I really like it.

Relaxing, yet Intense. Your Brain will thank you!. I'm critical of all apps/games though this is a Beautifully well done Masterpiece! Download it, you will not put it down. Use Headphones for a brilliant environmental takeover and NEW SOUNDS. New In-App purchase options available so you can unlock all levels and not get stuck on one which frustrates you to the point of wanting to hurl your i-device and yourself out of the nearest window. What's this clever infinity mode? Find out! Endless possibilities. How can one game be so silky relaxing AND pulse-driven intense? Minimalism at its most skeletal perfection! •I don't write Reviews but this is an exception to the rule. Amazing Developer, Cute, Humble, took time & love from Fans to improve an already 5 star game. Thank You so much 👏 Cyber Hug to you! ~From Texas with Love!

Fun game. The first couple levels are relatively easy. Can be frustrating at times, but it is challenging. Very addictive and makes time go by if u are bored. It would be nice if u are timed, that way you can beat your own score. Score should be based on how quickly you can accomplish the feat. Lower time better score, otherwise the game becomes redundant.

Hypnotic and Challenging. This game is beautiful, mesmerizing, and difficult. As the player, you must tap a small colored circle that will send out a widening ring of the same color. When the ring hits a smaller white circle, the level ends. Sounds simple enough, right? Well, as you progress, multiple circles of varying colors begin showing up and the white circle begins moving, presenting increasingly difficult challenges, but the result is always rewarding. If I was asked by someone if this game deserved a positive recommendation, I would certainly comply.

Makes you think. I'm not the type of person to play video games, nonetheless any app games. However I am loving this! It's not planting a garden for virtually no f%*#^^ng reason...it makes you think and concentrate about how you are going to get the prices to meet at the right time. While it is indeed pointless, aren't all apps? (Yes, even Facebook is pointless) however, this is where we are at...and I for one am glad there is a game that isn't stupid and also is neurologically helping me.

Minimalistic addictiveness. A gift from an ex sometimes is never a good gift at all- but he passed along this Starbucks app of the week card along to me and now considering getting back together with him. (Just kidding- its best we just stay friends). This game puts me in a state of both total relaxation and utter (at times) frustration. Just as I think I won't get past a stage- I do and back to zen. Info encourage you to spend the dollar or however much they charge if you're a game that you can pick up and go and put back down at a moments notice.

Hand, eye and ear coordination required!. I'm far from an expert at this app, but I do find it stimulating to the mind. I don't think it's as soothing as others find it, but that's probably because I think I'm not doing it correctly. But I do think it's helping me to become a bit more coordinated. My three-year-old son likes it, too.

My BP definately goes down while playing. You know those things we come across in life that make us ask ourselves, "why didn't I think of that"? I could be the one raking in the millions off a Pet Rock, the Chia Pet, the Clapper, Marilyn Manson. Well this exercise in Zen masquerading as a "game" had me pondering the possibilities yet again. All while evoking very warm emotions that will soothe, calm, and relax the Little Buddha that is in us all. The real magic however, is that unlike the chakra choking, mandala wielding Yogi's plying their trade on Barnes & Noble bookshelves across America, this little gem isn't getting shelved anytime soon.

Wicked neat. Very cool it's like playing a physic game for ur mind if u were crazy ya know so try it worth trying for sure not sure where they can go with it from this point though ..... There is only so many of those. Puzzles u can do u know so we see what happens try it in bout in out inboutttttttrtu I'm outttty latest layers laters rock roll

It hook you up!. The fact that the white dot move also make this puzzle game quite exciting. Timing is everything in this game. So your brain have to time several variables to catch the white dot at the precise moment. Some time you just to smash the iPhone to the wall, so be aware of that and buy a nice cover. The levels get frustrating but they are not impossible. Give it a try! You won't regret.

Relaxing, Challenging, and Sneakily Addictive. I love this game! The simple interface keeps it relaxing - single bell like tones that ring in harmony on occasion and expanding radar like rings. After a few rounds with a simple change in target it gets challenging and you will find yourself addicted!

Use your headphones for maximum effect!. Don't overthink while you play and you'll do just fine. The more you relax, the better you'll do. It's like watching ripples in a pond while you hear wind chimes. An evolutionary step in video games and it has a zen-like feeling. This is not your father's Angry Birds.

P31woman. I thought it was going to be boring. Then! I started getting the hang of it. Sometimes it's frustrating. But it's that bit of frustration that makes me feel the need to concur. I really like it! It makes you think!

Another quality app. After solving Even Up, I wanted to try this app from the same developer. I'm only a few levels into it and love it already. Great quality again. Simple concept, but still challenging and entertaining. Well done.

Different than the rest. Ive played many puzzle games out there and they usually end up copying the same ideas over and over. This game does something different, its not the typical puzzle game. I truly loved playing it. Good job.

Soothing. This game has the potential of being very stressful but yet it's not. I find myself going back to it more and more and think that it's a great game and well worth it easy to play on your ofttimes at work or if you have time to play at work.

Fun but challenging. This is an elegant, beautifully rendered game. The concept is simple, but it quickly accelerates in difficulty. You won't get far if you have only a few minutes to play between meetings; it takes real concentration.

Frustratingly simple, yet highly addictive!. It's a wonderful "game" to play when I need to refocus. The graphics are simple, the sound is a calming tone and I really feel my stresses melt away. I come back to center and have more clarity after playing.

Love It. This game is simple, but so fun! It's something I can play for extended periods of time and still enjoy. Some levels are really quite challenging, but it doesn't get frustrating when you have to do it over and over until you get it right.

Mindless distraction. If you want to play a game that is put down as easily as it is picked up, but is distracting enough that you forget yourself while you are playing it, then you should download this game. It is difficult enough that it is satisfying to play, but not addictive to the point where you waste time you should be using on other things (i.e. work). Perfect airport pass-time

Refreshing. This game is such a beautiful change of pace from the rest of those millions of games on the app store. It's a relaxing, challenging, and fulfilling game full of fun and innovation. When things are kept simple, they turn out beautiful. And that's exactly what this is. Simple and beautiful.

Relaxing fun!. Wasn't sure what to expect, but am happy I decided to purchase! I love I can close the app, re-open later, and pick up right where I left off. Easy to use, no issues as of yet. Almost meditative...really enjoying it!

Brilliant. I picked this up solely because I happened to be at Starbucks while it was the app of the week, and I love it. It's engaging, addicting, and just the right amount of frustrating. Simple to get the basics, and just enough challenge to keep you coming back for more. Bravo.

Very unique and wonderful game. Coming from a person who does not typically like playing games this is a great game for anyone! Challenging and relaxing. I am only guessing that it will have a positive effect on everyone who plays. This could be a simple yet beneficial game for our times.

Spatial reasoning. I enjoy this game as it makes me be more aware of my surroundings, and timing when to make a move. I think more about how individual elements move within a field. I can see where this could be good for children especially.

Simple, Addicting, and Musical. I have played through this game multiple times and by the time I beat the last level, I can start from the beginning again feeling like it's a whole new game because it is so entertaining. Great way to pass time!

Relaxing. This game is tranquil, and, unlike many other casual games, pushes its users to a patient approach. Those ripples only move at their own pace. The smooth animation and gentle sounds brings beauty and peacefulness as well. I hope this review doesn't scare anyone away thinking it will be boring. It is not, just let the game happen to you. You will enjoy it.

Patience can be a game. Patience can be a real game. I love it. This game allows you to test your hand eye coordination at the same time it test your ability to focus on the task. Nothing flying thru the air. Not a single zombie, or pig grunting. Just chimes, your brain working to focus on the white dot.

Simply Amazing. This game keeps you going. Always urges you to continue. Absolutely one of the best games i have ever played! Works your brain a little bit but i would certainly recommend it to anyone in search of a fun but time consuming game!

Addictive!. This is a Challenging & Beautiful game. I like that you can spend a few minutes at it and enjoy it, without having to complete a whole series of events before you can walk away from it. Easy to learn too.

Great!. Challenging, yet it’s so relaxing somehow. I guess that’s because the easiest way to get through a level that’s feels impossible is to let go—a very addictive way to learn how to not let stress control you, but how to chill out and more intuitively find your own solutions in life , beyond this game. I love it!

Perfect "before bed" Challenge. I typically never write reviews but I am very impressed by this app. It just goes to show that with a few simple sounds, some colors and a concept that genius can be created. Great to use to wind down after a long day!

Ambient activity. I like the tones and colors. Easy going game with no anxiety of having to complete the challenge with a timer or limited attempts. Would like to see a little more tracer-halo following the ring out, but keep the challenge of precision of timing the ring to the target tight. Keep the background the same. Thanks

Fun!. This game features simple but complex gameplay that at the same time is extremely addicting. The difficulty in this game starts out easy and quickly keeps increasing the difficulty and this game is also extremely relaxing.

Wonderfully Addictive then Frustrating. Initially it's calming, soothing then you become enthralled. Right about then you come across one of the "puzzles" that brought me to the point of complete frustration and out of character - At that point I realized I was addicted.

Dis game is great. I loveeee it soooooooooooooo much pd this game really tests your patience so if u don’t like that then don’t get this game. Other than that this game is good for your mind because you really have to think about your thinking (another word for that is metacognition) so yeah. 👍👍👍👍👍👍👍👍👍👍 🤗🤗🤗🤗 - skitpineapple signing out ✌️

Fantastically simple!. Beautifully simple design and intuitive gameplay make this a great game for all ages. It proves yet again that a game doesn't have to have all the bells and whistles to be enjoyable, nor does it have to have hidden in-game purchases to succeed. Lots of fun.

Surprising entertaining and challenging. This is a game that you can pick up from wherever you stopped last. It allows you to be challenged while not feeling frustrated or overwhelmed. Fun, and the tones make it even better

Different. This is a different kind of game and requires an alert mind. Didn't care for it at first but like and enjoy it now. Would help if instructions were available when first starting. I accidentally figured it out so instructions would be nice. Overall a challenging game. I like it!

Interesting. I thought this was a very different type of game. It challenges you in a new way. Some levels were tough and I just wanted to delete the app out of frustration. After trying again another time, I finally got it!! Not addictive, just challenging for the brain! Pretty good!

Impressive. Simple. Beautiful. Pleasing. Only complaint is that the easy levels were too few. The game goes from super easy & fun...straight to really hard. I would throttle the fun to make it longer lasting. I've played the game for 30 minutes now and I'm already getting annoyed at how it's becoming more about luck than skill.

Clever and entertaining. This is a great simple game that engages some thinking and is not too complicated to get started. It does become harder, and maybe many people will bore of trying to figure it out and leave it for awhile, but I think it will be something they could come back to later and enjoy.

Fabulous. I'm not one to play games on my phone, but when I saw my brother playing it on his iPod, I had to try it. It's so addicting, but relaxing too. It's all about the timing, and can be frustrating. But hey, that's a reason why I love it. Highly recommend this for all ages.

Mohammad Mohammad. This is a very fun and yet hard to play , it makes you think and calculate for each time you try to touch any of those. Circle. Is not like any other play app. Thanks again for providing this fun and challenging game. Thanks to designer/s. ...❤️😎

Like Slo-Mo shooting gallery. This isn't a game of speed, it takes observational skills and precise timing to advance with this game. Something I thought I was pretty good at!, I'm not as good as I thought;-(. It's a real challenge. You have to think about what you need to do to get to the next level. Have fun!

Simple yet captivating. The concept is simple but each screen gets just a little more difficult - just enough that you keep at it without getting frustrated. Entertains multiple ages; I enjoy it as do my 6 & 7 year olds. And the chimes of the dots are soothing.

Fun, joyful yet edgy. This is a great game that has you figuring out which circle is fast, slow and going to touch the dot all in the same time. It's fun, heart pounding, intense and sometimes boggles your mind how to accomplish that level. Overall fantastic game and ready for more so I got to stop writing!

#Circadia. Downloaded about an hour ago & already my favorite game. Just tweeted (@PabloDeFleurs) that it's quite possibly the best .99 cents I've ever spent! Challenging - pulsing circles emit varied auras which the player must anticipate to have them converge on a white, sometimes mobile, white dot. Brilliant!!

Great Game. Very modern and minimalist looking - pleasing to the eye. Finally just beat the last level! Becomes increasingly more difficult (especially the last 10-15 levels). Had a very difficult time with level 100, but it's worth it! Very rewarding.

Cool concept. Interesting concept for a game. The only thing that I would change is the ability to listen to other music while playing. For example, I would like to be a listen to a podcast while also playing the game.

A very well done game.. It's nice to see and hear a challenging game. From the stand point of me being a drummer and timing being everything, this was still challenging. It is creative and will have you yelling at your phone because you can't get the timing right.

Calming and yet.... Love that you can change to audio to suit your tastes. My son likes piano while I like the chimes. It is engaging but relaxing enough to sleep after playing, which is kind of the point, isn't it? Thanks for helping insomniacs everywhere.

Fun mental break... Sort of. I play this when I'm bored and it stirs up my cognitive brain power which in turn stimulates me to be productive :) I don't play often... But when I do... I get a lot done after :) oh and I love the harmonica and the way the colors blend together ... So cute!

Pretty good..... I feel that this app is very good and simple. However I feel it has a lot more potential because even though I was enthralled by how simple and complicated this app was I feel it could've added more to keep my attention. But I still feel this was a very good app. #morelevels?

Very interesting. This is a very interesting app. Just when you think you got it, it changes. Also, I can't decide whether I am relaxing or pepping up. You get a physical response just trying to make that ring go a little bit faster!

Simple on the Surface.... Starts off pretty simple but once you get the hang of it takes strategy and timing to move through the upper levels. Entertaining and challenging game without all the buzzer and flashing lights. Makes you actually think a little!

A marvelous relaxing 'game'.. A marvelous relaxing 'game' that challenges your patience and yet brings it out as well due to its harmonic features, for lack of a better word. I highly recommend this as a way to just enjoy some quiet introspective time while you relax.

Simple, mesmerizing fun. Each game, each level, makes you slow down, pay attention to the rhythm of the tones as the circles expand, and try to gauge where they meet. This is a great way to pass time on a flight.

Wonderful "game". I don't review most of the apps I use (I really should) but I just had to on this one. It is so simple but beautifully made. Stress relaxer, great to meditate to, and can be challenging. I love it and don't see how it could possibly be improved upon. Thank you, dev team!

Circadia rocks. This game design is unique, different, catchy, and fun! Some levels can be a little tedious and complicated, but still simple enough to where it never takes me more than five or ten minutes to complete the harder ones. Great game for all ages.
