Have you ever wished you could recognize the constellations but didn't want to study those paper star charts? Sky Guide's augmented reality (AR) mode makes learning your way around the sky clear and effortless.

Exactly how an astronomy app should be  RazDaz007  5 star

Simply the easiest to use, most information-laden astrological interface known to earthlings. Worth every sky-inquisitive penny!

We love this app  hottiemom  5 star

At night we always go out and look where planets are and even satellites. It’s great fun if you like stars! And who doesn’t ;)

Ruminating? Depressed? Star Gaze!  RockMaxB  5 star

Unfortunately, I’ve battled depression since my teens, but early this year, my counselor suggested the way my mind ruminates over real and perceived issues, I was making myself more and more depressed. The most troubling time for me was taking my dog for a long walk late at night. I thought about every bad thing that had happened and was likely to ever happen! Then I started walking with my Sky Guide app in hand. Rather than focusing on all the bad, I was able to stay in the moment and truly appreciate the beauty of the sky. The change for my life has been profound! My mind is clearer, and my mood is much happier and More content! I am convinced the Sky guide App has been a major contributor to the quality of my life, and it may have been a part of saving my life. Thank you...


Far and away the best app of its kind  JBone320  5 star

I’ve had this app pretty much since it was released. It is far and away the best stargazing/sky reference app available. It’s full of features and detailed information on everything- be it planets, stars, satellites, rockets, space debris, galaxies, constellations, etc. I recommend it to people all the time. Most importantly, when people start pulling their phones out to check out the sky at night, they always end up saying “wow which app is that?” and delete the one they had and download this one instead. That’s really all you need to know. Also something I like is that it doesn’t have the cartoonish feel of many similar apps. Really just can’t stress enough how much this app is better than the rest.

Astounding!  Motchy94  5 star

This app blows my mind every time I use it. Just this evening I was working away when it reminded me the international space station was passing over. Walk out side and there it is! I’ve used the app all over the world and can’t rate it enough

Ross from Australia

Needs tweaking for Southern Hemisphere  Ross from Australia  3 star

When I tap the compass icon, it immediately spins around to the diametrically opposite direction- northeast becomes southwest. It would be great if it was more reliable.

Love this app!


Perfect  Lamadge  5 star

Just the right app to help me identify celestial items. So easy to use - just point. Identifies planets as well as stars. Used during the solar eclipse to track position of sun and moon until it was time for the special glasses. Fun to point at the ground and see constellations from the other side of the world.

New problems  Kampcachefis  2 star

I love this app. It’s by far the best sky viewing app on the App Store, but unfortunately the compass has been pretty far off for me lately. I tried to reinstall the app but it still doesn’t work. I made sure the date was set to the current time but it is still quite off even online. Please fix! I used to love this app but now It’s not showing the stars in the right place. I would have previously rated this 5 stars in a heartbeat. Please fix!

AR mode in iOS 11 is stunning  Cearbhall  5 star

I can finally see what the AR fuss is about. Sky guide makes great use of the iOS 11 augmented reality feature to give a seriously cool and fun AR mode. You have to see it in real time to get it. Stunning.

Best app I've ever used  ILOVESKYGUIDE  5 star

This app gives me hours of constructive and exciting entertainment. By far the best value for an app like this, I would value this (and spend) about 20 euro for this it's so worth it for astronomers like myself, beautiful visuals and sounds absolutely brilliant.
