Game
The game is designed to teach the user to recognize all the 88 modern constellations, brightest stars and 110 Messier Objects by taking them through a number of levels. Levels are divided into categories (constellations, stars & DSOs), regions (north, equator, south) and difficulties (easy, medium, hard). Each level teaches only a small number of objects and then trains the knowledge in a quiz game to aid memorization. Later levels also review and retest the knowledge of previously learnt objects.

Levels
In each level, you're first given an opportunity to see and memorize the objects (constellations, stars or DSOs) of that level. Use the arrows to go through all of them, and click 'Start' once you're ready. The description of each object is displayed on the panel at the bottom of the screen. The panel can be expanded by dragging it up to show more details about the object. After clicking “Start”, an object will be shown and you’ll be presented with 4 options. The level ends when you answer a certain number of questions (shown in the top-left corner) correctly. At the end of the level you'll have the opportunity to review the mistakes you’ve made before progressing further. Please note, in challenge levels, no hints are available and you are given only a limited number of lives to pass them.

Difficulties
Each level is available in 3 difficulties: easy, medium, and hard.
Easy levels show the lines of the constellations, making the experience less similar to the real night sky, but it's the first step of learning.
Medium levels hide the lines of the constellations, but show their precise borders and the lines of the surrounding constellations to help the recognition.
Hard levels are closest to the real night sky: they only show the approximate location of the objects, instead of the exact shape (the borders), and randomly choose the orientation each time, so that you learn to recognize the objects from another angle.
We recommend going through each difficulty, from easy to hard.

Explore screen
The explore screen (third button on the main screen) allows you to explore the sky on your own. Tapping on the objects (e.g. names of the stars or constellations) shows more information about them (e.g. abbreviation, brightest star, area of the sky, distance etc.). You can also use the same double-tap gesture to quickly hide/reveal all the decorations. The search icon (top-right corner) allows you to quickly find a particular object you're interested in.

### 5/5 — good app

*2026-04-04*

why doesnt zeta persei simply eat his smaller neighbor?

### 5/5 — unable to purchase premium (fixed)

*2025-02-09*

i’m trying to purchase the premium version but whenever i click on it, it crashes and i’m unable to purchase. despite the problem, this app makes learning the night sky easy and fun, and i’d love to access more with premium.

edit: i was able to purchase now! thank you so much!

**Developer response:** Hi friend, thank you for your feedback. This is caused by the new version of iOS and we are trying to fix the bug across all our apps. Once the update for Sky Academy is available, please update the app and the problem should be resolved. Thank you for your patience.

### 5/5 — Very effective

*2025-01-17*

I love astronomy and this app helped me learn more about space and constellations ,it’s just a bit annoying because you have to pay 5€ to get some things .Overall it is a good app

### 5/5 — Awesome but the purchases....

*2024-12-10*

I learned all the constellations possible, but it's tough that they charge $5 for more. Please change this and I have an astronomy unit in science coming up. Please remove the payment. But five stars for the memorizing!!!

### 5/5 — Best app ever!

*2024-12-09*

Best app for learning constellations. Absolutely wonderful and fun

### 5/5 — Learning that makes sense

*2024-06-12*

At first, I didn’t think this app was really teaching me anything more than how to recognize a few patterns with the assistance of borders and lines, but after getting through some of the beginner lessons, I see the patterns are starting to burn in. The lines and borders start to go away the higher the difficulty. I also like being able to simulate my light polluted sky and see the same challenges with fewer stars. Absolutely the best tool for any hobbyist looking to try astronomy.

### 5/5 — finally

*2024-03-03*

staring at planetarium apps is slow and cumbersome 
the best way to learn the stars and their common names is with this app

### 5/5 — Lo

*2023-08-19, version 3.0.1*

Yay now I know stars. Love this creator their Morse code apps are really well done too.

### 5/5 — Love it

*2023-07-24*

I have gone down the Astronomy rabbit hole. I was looking for something to quiz and teach me the constellations and stars and this app is great!! There is no app better at teaching you the constellations and their locations. Thanks to the developers. I love that I can make my own custom quizzes.
