SkySafari 6: The Best Overall Stargazing App
SkySafari comes in three tiers: the basic version (free, limited catalog), Plus ($14.99), and Pro ($39.99). For most beginners who plan to stick with the hobby, Plus is the sweet spot. It includes 2.5 million stars, over 31,000 deep-sky objects, and full telescope control for most major brands.
What it does well: SkySafari's object database is unmatched in the mobile space. It renders realistic star fields, includes detailed descriptions of every object, and lets you simulate the sky at any time and date. The telescope control feature works with Celestron, Meade, Sky-Watcher, and Orion mounts over Wi-Fi or Bluetooth. You tap an object, hit "GoTo," and your scope slews to it. If you own a telescope with automatic tracking, this is the app that makes it sing.
What it lacks: The free version is too limited to be useful. The UI feels dated compared to Star Walk 2. The learning curve is steeper than simpler apps, and the AR mode, while functional, is not as visually polished.
Who it's for: Anyone who owns or plans to buy a computerized telescope. Also great for observers who want to plan sessions ahead of time, filtering objects by magnitude, type, or constellation.
Before heading to a dark-sky site, download SkySafari's extended star catalog over Wi-Fi. The app works 100% offline after that, which matters because most great observing spots have zero cell signal. The same applies to Stellarium: grab the extra catalogs at home.
Stellarium Mobile: The Best Free Option
Stellarium started as a desktop planetarium program in 2001 and has been open-source ever since. The mobile version comes in two flavors: Stellarium Mobile Free (completely free, no ads) and Stellarium Mobile Plus ($13.99, adds telescope control and an extended catalog of 1.7 billion stars from the Gaia mission).
What it does well: The free version includes over 600,000 stars, realistic Milky Way rendering, constellation art overlays, and time simulation. It is genuinely powerful for a free app. The rendering is accurate enough for planning astrophotography frames. The web version (stellarium-web.org) works on any device with a browser, no install needed.
What it lacks: The free version has no AR mode (you need Plus for that). The mobile UI can feel cramped on smaller phones. Telescope control in Plus is more limited than SkySafari's, supporting fewer mount brands. There is no satellite tracking built in.
Who it's for: Anyone who wants a serious planetarium app without paying a dime. If you are deciding between alt-azimuth and equatorial mounts and need to visualize how objects move across the sky, Stellarium's time-lapse simulation is incredibly helpful.
Star Walk 2: The Best Beginner Experience
Star Walk 2 costs $2.99 for the ad-free version on both platforms, with a free version that includes ads and limited content. In-app purchases ($0.99 to $4.99 each) unlock additional content packs for planets, deep-sky objects, satellites, and meteor showers.
What it does well: The visuals are the best in class. Star Walk 2 makes stargazing feel like a cinematic experience, with smooth animations, beautiful constellation artwork, and an intuitive point-and-identify interface. The "sky live" widget shows you what is visible tonight without even opening the app. The AR mode is clean and responsive.
What it lacks: The star catalog is smaller than SkySafari or Stellarium. There is no telescope control at all. The free version has frequent full-screen ads that pop up at the worst times (like when you just got your eyes dark-adapted). Some content packs that arguably should be included, like satellite tracking, cost extra.
Who it's for: Complete beginners who want something pretty and simple. Also great for showing kids the night sky, since the interface is self-explanatory. If you want to check what magnification you need for planets and then find those planets in the sky, Star Walk 2 makes the finding part easy.
Switch your stargazing app to red/night mode before you step outside. Your eyes need 20 to 30 minutes to fully dark-adapt, and one glance at a bright white phone screen resets that clock completely. Every app on this list has a red mode: use it. On iPhone, you can also enable the system-wide Accessibility red filter for apps that lack a built-in option.
Sky Map & SkyView: Best for AR Identification
Sky Map (Android only, free, open-source, originally Google Sky Map) is the simplest possible stargazing app. Point your phone up, see labels on stars and constellations. No frills, no paywalls, no ads. The catalog is limited and the visuals are basic, but for a quick "what is that bright star?" check, nothing is faster.
SkyView Lite (iOS and Android, free) takes a similar approach but with a more polished AR overlay. The full version ($2.99) adds satellite tracking, an extended object database, and Apple Watch support. SkyView's AR mode works well in both dark sites and light-polluted cities since it overlays labels regardless of what is actually visible to the naked eye.
Neither app supports telescope control. Both work offline. If you are on iPhone and want a free AR identifier, SkyView Lite is your best bet. If you are on Android, Sky Map is lighter and faster.
Satellite Trackers: Heavens-Above & ISS Detector
None of the apps above specialize in satellite tracking. If you want to catch ISS passes, Starlink trains, or bright satellite flares, you need a dedicated tool.
Heavens-Above (Android and web, free) is the gold standard for satellite pass predictions. It provides exact times, brightness magnitudes, and sky charts for every visible pass from your location. The web version works on any device. The interface looks like it was designed in 2005, but the data is unmatched.
ISS Detector (iOS and Android, free with in-app purchases) is friendlier. It sends push notifications before visible ISS passes, includes an AR compass mode to point you in the right direction, and has add-on packs ($1.99 to $2.99) for amateur radio satellites, Starlink, and bright comets. For casual ISS spotting, this is the easiest option.
Which App Should You Download?
- You just want to identify stuff for free: Stellarium Mobile Free (any phone) or Sky Map (Android)
- You want the prettiest, simplest experience: Star Walk 2 ($2.99 ad-free)
- You own a GoTo telescope: SkySafari 6 Plus ($14.99), no question
- You plan serious observing sessions: SkySafari 6 Pro ($39.99) for the deep catalog
- You want to track the ISS and Starlink: ISS Detector (free) + Heavens-Above (web)
- You want one app that does most things: Stellarium Mobile Plus ($13.99) balances features and price
- You are buying for a child under 10: Star Walk Kids ($2.99) or the free NASA app
Most experienced amateur astronomers end up with two or three apps on their phone: one planetarium app (SkySafari or Stellarium), one AR quick-identifier (Star Walk 2 or Sky Map), and one satellite tracker (ISS Detector or Heavens-Above). That combination covers every scenario from backyard sessions to dark-sky trips.
Do not hold your phone at arm's length and assume it is pointing accurately. Most stargazing apps rely on your phone's magnetometer (compass), which drifts. Calibrate by moving your phone in a figure-8 pattern before each session. If objects seem offset by a few degrees, this is almost always the cause.
Free apps like Stellarium and SkyView Lite are more than enough for most beginners. You do not need to pay for premium features until you are ready to plan detailed observing sessions or control a computerized telescope.
