Which star is this? Where do I find Mars? Is it the ISS up there? Hold your smartphone or tablet up to the sky and see which planets, stars, or constellations are above you.

Where is Jupiter and how can I find my zodiac in the sky? The Sky shows you the position of celestial objects in the sky with just a few taps. Get close-up views not only of near-Earth planets and moons, but also experience deep-space objects in stunning detail.

What do the Saturnian moons look like? The Sky takes you on a breath-taking journey into the infinite realms of outer space. Fly to planets, stars, and other celestial bodies and let the app tell you about our Universe.

What is a solar eclipse and what does an opposition of Mars mean? The Sky answers your questions with stunning animations and insightful explanations. Thus, even beginners will be able to understand the mechanics and to visually imagine the most important celestial events.

### 5/5 — Прикольно!

*2026-03-01*

Очень прикольно!🥰

### 5/5 — So Cool

*2025-02-10, version 2.0.9*

Expertly done for FREE

### 5/5 — Reflecting

*2024-10-16, version 2.0.3*

What happen to mercury when the sun dolor got hit last year

### 3/5 — いろいろと残念

*2024-07-13*

画面はきれいだし、青雲や星団の位置まで 載っているので楽しいです。 でも星座のつなぎ方とか星座絵がおかしいこともあるので、正確さに欠けていると思います。 かに座の中にはザリガニではありませんよ。 こと座の星座絵もずいぶんと変な絵ですね。 おとめ座のような12星座は日本で一般的に 使われている形に星をつなげてもいいと思います。わし座もはくちょう座も同様です。 せっかく星雲星団のを載せているのですから M27とからM57のようなメジャーな メシエ天体くらいは表示してほいしものです。 さんかく座の系外銀河は「さんかく座銀河」と表示されていますが、これはM33でいいと思います。メシエナンバーなつくほど有名な天体ですから。
  もしかして開発者さんは日本の天文の本を 読んだことがないのでしょうか？ 星座のつなげ方やあてはめる星座絵が 普通とは違っていたり、 日本では子供向けの天文の本にも 載っている天体を知らないのは 外国の知識のせいかもしれません。 せっかくきれいな星空を映し出せる のですから、もう少しお勉強して ほしかったです。 あちこちに違和感を感じるので 使うには不安を感じるアプリです。

### 5/5 — 👇🏻

*2024-05-24*

Все отлично но можно сделать сделать 3 д спутники пожалуйста

### 5/5 — Magnifique application ma préféré

*2024-01-01*

Après avoir chargé et déchargé presque toutes les applications dans le but de voyager ou repérer les étoiles galaxies,  j’ai enfin trouvé! où l’on peut aller presque partout dans son coffins en cochant les étoiles proche de la galaxie lointaine recherché par exemple. On à vraiment l’impression de voyager à la vitesse de la lumière. Merci j’adore. Seb

### 1/5 — Ads. I’m deleting it.

*2023-08-10, version 1.1*

Too many; too disruptive.
Sad, because I was an “early adopter” of Redshift decades ago, pre-APPs, and loved it.

### 1/5 — Leider schlecht

*2023-06-16*

Anstatt mit der Klasse Interstellar zu schauen bringt uns unsere Lehrerin dazu eine Stationsarbeit mithilfe dieser App zu machen. 
Warum wir kein Interstellar zum Thema Astronomie und interstellare Reisen schauen weiß keiner.

### 4/5 — Wishes: red light option and others

*2023-04-23, version 1.1*

I wish there was an option to show things in red to preserve night vision. 

Also, the "pointer" takes up a fair amount of screen real estate (blocking other things) plus it's big. 

I wish it was a just a thin circle with some centering marks (but not blocking the middle sight.). Maybe a bit like a magnifying glass.

### 1/5 — Too many ads

*2023-02-20, version 1.1*

Forces you to buy premium.
