C25K® 5K Trainer Pro Reviews


Finished first 5k  Chadferguson  5 star

I’m 310lbs started at 325 when I first downloaded the app. With this and changing my diet I was able to do my first 5k on St Patrick days weekend. I have never been more thankful for an app to help build my stamina in a way that made sense. Thank you again. Never thought I could do it.


Really for beginners  ytrewq147  1 star

I was looking for son to help me get back in shape after pregnancy but was already running 2+ miles. It starts out so slow that it was a waste for me. Oh well.


No notifications with Watch App  ThreeDeltaSierra  1 star

Upgraded to the Pro version for the Apple Watch support, but it does not play an alert tone when switching from run to walk and vice versa. You have to look at the watch to see what interval you are in. Cmon Zenlab, phone app is great, watch app not so much.


Useless  deeze03  1 star

Decided to get this since it’s available on my Fitbit Ionic but apparently there is no way to sync the Ionic app with the phone app which makes zero sense. What’s the point? No real way to sync with other fitness/weight loss apps either. I’ve got a half dozen different things I use and they can all talk to each other easily but not this. By far the least user friendly fitness app on the market. Don’t waste your money on it.

Susan McClyde

Haptics/alerts not working properly on my S4 Apple Watch  Susan McClyde  1 star

I’m attempting to use the pro version as stand alone on my watch and am really disappointed so far. The alerts sporadically work and usually, only when I raise my wrist to check interval progress. I ran today and over-ran the running intervals and over-walked the walking intervals. But I get alerted “properly” when the workout is complete? Not helpful.


Apple Watch stand alone doesn’t work.  CMeyer2001  1 star

Have tried multiple times to use without my phone. I receive no notification to run or walk. Big disappointment as I don’t want to bring my phone along on workouts. Support hasn’t been helpful at all.


It works!  Tail24  4 star

So like most people looking at this types of app here, I wanted to get off the couch and get my butt moving. I’m a former state place finishing wrestler and college football player who 20 years ago was in peak shape... on January 1st 2019 I was far from that. I know how to properly diet when I want to but I’m not consistent at it and was about 40 lbs over weight and about 30 from where I’d be happy. I knew I could diet it off but it would come right back on so decided I needed to change my lifestyle and get running. To me running has always meant one thing, getting my wind up for wrestling and I’ve never enjoyed it. I wanted to change that. So today I just finished the day I was dreading as I clicked through the workouts 5 weeks ago. 5 minute brisk walk then 2 miles straight running. Ahhhhh!!! Never saw myself completing this day a month ago. Today I did an extra qtr mile on top of it to get home. The app is mostly interval training that starts what today seems so easy but on day one I begged for each beep of my phone to come to end the running portions. Gradually those only came on the first day of the weeks.... then they just disappear. I’m running, not hating it and I’m impressed. Only reason for not giving 5 stars is its missing good data collection, I have to use separate apps to track data in the background like heart rate and pace. Second flaw is not on the Apple Watch. I wish I could just go out without my phone and it would run. Thanks for helping me become health and get off the couch. Oh and readers don’t forget to stretch!


Stop annoying me!  manicxs147  1 star

If they didn’t keep prompting me to review this app I would have given it a better score


No prompts when using on stand alone Apple Watc  Janethedrain  1 star

This app was purchased so I could use on my new Apple Watch, as it states must buy Pro for stand alone watch. I cannot get any cues through my air pods...I am running Nike Pro at the same time...it supplies miles and splits... but nothing from c25pro...no voice cues! I can’t be looking down and switching screens to see if it’s walk or run time! Jane


Here we are Jan. 2019 and problems still arise,  Jazziedoodle  1 star

I have read some of the reviews about the lack of notifications when you try to use the watch alone. I also saw the replies. I just bought this, so it SHOULD be updated, but it still has those problems. I have the Series 3 and have the flexibility to just take my watch for activities such as this, but when you read reviews about it being fixed, go and buy the app, and it STILL doesn’t work, it’s disappointing. I almost want my money back. I mean, it’s $4.99-but I want to see a for real update.


Not worth it.  ghostie99  3 star

Does what it says on the box, however even the paid version wants to sell your data and the watch app frankly is rubbish.


Third party tracking  sanswork  1 star

The paid version requires you to consent to them selling your location data to two different companies before you can use the app. The are a lot of other c25k apps or there and because of this I'll be using them now instead


Needs work  Emiichan  1 star

I love the simplicity of this app but the watch app needs work. I did not pay $8 for the watch app to not notify me when to start walking or jogging. There’s no noise or vibrating unless you have the app running in front of you. It’s extremely frustrating during your workout. I want to be able to use this app with watch only but it makes it too hard. I’m disappointed I spent money on this so far.


Ok but could be better  Emily_aus8  3 star

I’ve used a couple of C25K apps. This one looks nice but could do with a few improvements. Firstly while the interface is clean, a number of the metrics are too small to read such as “2 of 6” runs. Another improvement would be the voice telling you when you are starting the final run of the set as this brings some relief to know you are almost there. The watch app is useless. A functional watch app that doesn’t require the phone would be beneficial as exercising was the main reason I got an Apple watch. Notifications need some work. I did a run at 5:50am but got a notification at 9am suggesting I ‘dust off those running shoes”. I still start an Workout on my watch at the same time as these app doesn’t work with the Apple Health or Activity app.


Disappointed  KB175  1 star

I thought for $8 I would get a running app with all bells and whistles especially included music. It’s not a bad app but for the price the music should be included. LoLo have a fantastic running app which includes music which varies with your speed.


No tone in air pods  mattshur  1 star

You don’t here the tone in AirPod if using only watch


Great app!  Bluejasmine2  4 star

It’s getting better but I would like to link it to My Fitness Pal and Fitbit.

Rasputin Jones

Decent app, great system, poor watch integration  Rasputin Jones  3 star

The app isn’t bad. A little cluttered perhaps. I’ve used various iterations of C25K over the years and they’ve never failed to get me back into running again. However this time I paid extra for the new version because it had iWatch compatibility. It does not have iWatch compatibility. The watch interface needs to have nothing more than a stop, go and pause button and the prompts delivered from there. This is important because the current version of the watch shares internet access with the phone which means I don’t have to take the phone at all but the watch app has little more than a single page that says “start workout on phone”. Though I was disappointed that I now needed to carry the phone too, I could have put up with it if the app even worked but unless I unpair my headphones from the watch and pair them with the phone, I don’t get the audio prompts. Hell, most of the time I don’t even get the haptics and notification. I know you guys can do better. AppName: C25K® App Version: 4.2/126 Device Model: iPhone8,2 OS Version: 11.2.6


Great way to get back into or start running.  O4ramo  5 star

Great app gets me on track without pushing to hard or going to soft.


App is American-centric, support is dull  MagicTomo  4 star

For an app with a metric name, the distances within are imperial (and hella outdated for modern earth standards). Emailing support with issues (such as no 'treadmill' option resulting in woefully inaccurate calorie burn estimations in linked apps) will give you a pointless response paraphrased from the FAQ. So don't expect feedback to be valued. Otherwise the app functions well for what it is. Stick with the free version. You're not missing anything by paying.


Do not buy this app  DoNotBuyPro  1 star

This app is not worth the $5. The free version of this app is great for the iPhone. This paid version adds little value to the experience. I bought this version because of the Apple watch app, but it is worthless. You have to start the run using the phone and you cannot pause/resume your run from the watch. In addition, even if you choose to run with your phone you will not get notifications to start running/walking on the watch. I’m not just disappointed with this purchase, I’m actually angry.


No Better than the Free Version  okrun11111  2 star

I paid for the distance/calorie tracking upgrade thinking it would map where I ran. It doesn’t. I run different routes and I’d like to be able to compare a route from one run to the next. Not at all worth $5.


Good plan, strange execution  Jrgsxhh  2 star

Overall, I believe this is a quality couch to 5k program as it’s similar to ones I’ve used in the past. I appreciate that it’s not chatty and bombarding me with encouragement all the time. I really like that a whole lot. Redoing workouts when needed in other similar programs had always been kind of annoying because the script gets predictable. My issues with the app however will take some getting used to for the purchase price to become worthwhile. I would love to be able to get the app to stop asking me to legit join up with apple health. I use a Fitbit for monitoring stuff and don’t have any interest in using apple health because it complicates Fitbit usage. Fitbit integration would actually be awesome. Second, the music interface is slow and weird and that’s a huge sticking point for me. It takes unnecessarily long to respond (to be fair I’m using an iPhone 6, but it’s not like this app should be chewing up serious processor capability) and at times covers over portions of the screen, preventing access to things that need to be clicked (like at the end of a workout and the award of a trophy. I had to kill the app because there was no other way to exit to anything). Last, the music player doesn’t stop when force-closing the app. When I killed the app to get away from the trophy screen, the music kept playing. I double checked to be sure it was closed and it was. I waited out of curiosity to see if it would continue playing music after the current track finished. It did. Very strange behavior in my opinion. Anyhow, this might not be the couch to 5k experience for me or maybe I’ll get used to it but my initial impression is that it’s seriously irritating to use.


Disappointed  Pjorgfl  1 star

I’ve done the C25K program before and it’s a great program. When I decided to purchase the full version of the app it was because I was under the impression that it would work on my Apple Watch without the need to have my phone on me as well since my watch has cellular. That is not the case. Not being required to have my bulky phone with me on a run is 90% of the reason I bought the watch with cellular in the first place.


Needs work  ShayiPhone  4 star

Please allow it to send voice cues when using our iWatch. It’s hard to watch a watch and run.


Does not work with Apple Watch  Gentlehandz  1 star

I am not able to start with the watch I have to use my phone to start stop and pause so essentially it’s worthless because I do NOT bring my phone in the gym I want a refund


Glitches  RedRedLes  2 star

Really glitchy. Not an easy user interface, didn’t work well with Spotify. Returning it to get my money back. I did like their playlists but not that you had to pay $5 a month for them.


No HealthKit  AveyWatts  1 star

I have been using this app for a couple years, it’s still pretty buggy but is also the best option on the market for couch-to-5k apps (which makes me a little sad...) I first downloaded C25k around 2014. Somehow they have been able to create a monetized music streaming services, but it is still so difficult to integrate HeathKit, which was designed to be relatively simple to add into current apps. I purchased the Pro version, only to have access to the Apple Watch app, which lags behind its iPhone companion by 10-15 seconds. So... really, it’s the best option (with worse competition) but it’s also seriously lacking features that make it a better user experience. (Yet somehow the develop team is able to create and push a weird music screaming app, Among other things.)

2nd time I’ve used this app  Becca1 R  5 star

Thanks to this app I’ve taken my lunch hour and can run a 5 k now! Highly recommend


Watch integration is a joke  Tston  2 star

The integration with the Apple Watch is TERRIBLE. Notifications may or may not come through based on the state of the phone in my pocket.

No K in C25K!

No K in C25K!  No K in C25K!  2 star

The app works fine, but despite the fact that 95% of the world's population uses the metric system, and the 'K' in 'C25K' standing for 'Kilometres', the developers have neglected to give you the option of using metric/kilometres. Instead distances are measured in miles/ parts of miles!

Basic  Ruth Sheridan  2 star

Basic App, no bells or whistles!


Mrs  Sionall  3 star

As a beginner I fine this very useful.


Bog standard  harrybdublin  2 star

This app tells you when to run and when to walk, no more no less, I have had to use Runkeeper to keep track of the pace and the distance, it gives no information about your workout, it just ends and moves onto the next day
