The best stargazing apps for Android in 2026 are SkySafari 8 for serious observers, Stellarium Mobile for a free photorealistic planetarium, and Sky Tonight as the best modern all-rounder with comet tracking and event alerts. For the ISS, add ISS Detector; for planning around cloud and seeing, add Astrospheric. Every pick below is live on Google Play and was updated within the last year — no dead or iOS-only apps.
In short: top three picks
- SkySafari 8 Pro (US$49.99) — the serious observer’s choice: deepest databases, event finder, telescope control. Version 8 finally reached Android in March 2026.
- Stellarium Mobile (free; Plus upgrade) — the best free tier in the category and the most visually accurate sky rendering on mobile.
- Sky Tonight (free) — the most polished modern guide: AR pointing, event calendar and comet tools, updated steadily through 2025–2026.
Why this list changed for 2026
The category moved since older roundups. SkySafari 8 shipped for Android in March 2026 after years of iOS-first releases; the community-maintained Sky Map had its most active year ever; and the 2026–2027 eclipse corridor plus a busy comet season pushed apps toward event alerts, comet visibility tools and astronomy weather. Several older entries no longer qualify: Night Sky (iCandi) is effectively iOS-only and gone from Play; Star Chart hasn’t been updated since April 2024 and paid upgrades broke for users; the Astronomy Magazine Android app is defunct; and “Sky View Free” was just SkyView Lite under a second name. They’re replaced with apps verifiably current on Android.
The 11 best stargazing apps for Android
1. SkySafari 8 Pro — best overall for serious observers
Price: Free Basic tier; Plus US$29.99; Pro US$49.99, one-time, with frequent discounts. Verdict: The deepest database and most reliable GoTo mount control on Android, but priced and built for serious observers only. Best for: telescope owners and deep-sky observers.
SkySafari is the app experienced amateurs install first, and version 8 — on Android since March 2026 — adds built-in plate solving (identify what’s in an image and lock it onto the chart) and better event-finding. Pro covers over 46 million stars and hundreds of thousands of deep-sky objects, and it remains the most reliable way to drive GoTo mounts over Wi-Fi: tap an object, the telescope slews to it. The catch: it’s expensive and more than casual users will ever need.
2. Stellarium Mobile — best free planetarium
Price: Free; Plus unlock is a one-time purchase or subscription, region-dependent. Verdict: The most physically accurate sky rendering on a phone, though telescope control and the full catalogue need the Plus upgrade. Best for: a beautiful, accurate sky map without paying.
From the desktop Stellarium team, this offers the most physically accurate rendering on a phone: real star colours, atmosphere, multi-culture constellation art and accurate planet positions. The free tier is genuinely useful, not a demo. The 2026 update (v1.14) added camera-based AR and guided “Tours”; Plus adds the full Gaia catalogue, telescope control (NexStar, SynScan, LX200) and offline packages. If you install one free app, this is it.
3. Sky Tonight — best modern all-rounder (new addition)
Price: Free with ads; optional subscription removes them and unlocks extras. Verdict: The best-maintained free guide, with comet tools and alerts that keep it ahead of older rivals; the free tier carries ads. Best for: beginners who want alerts, comet tools and a clean AR view.
From the makers of Star Walk, Sky Tonight is the best-maintained free guide on the store. Point your phone and it names what you’re looking at, then goes further: a visible-tonight list for your location, a searchable event calendar, and comet tracking updated as recently as August 2026 for Comet 220P/McNaught. An image editor annotates and shares sky shots. Ads at the free tier are the main annoyance, but most users never need to pay.
4. Star Walk 2 — best for beautiful, guided discovery
Price: Free with ads; Plus subscription removes ads and unlocks catalogues. Verdict: Beautiful and easy for a beginner, but it overlaps so heavily with Sky Tonight that you should install one, not both. Best for: visual learners and kids.
Star Walk 2 remains the prettiest beginner app: hand-drawn constellation art, smooth planet flybys, a live sky view. A notable update landed in September 2025, plus a “Planet Walk” mode. It overlaps heavily with Sky Tonight (same developer, same sky data) — choose Sky Tonight for stronger event tools or Star Walk 2 for the friendlier illustrated interface. You don’t need both.
5. SkyView Lite — best for instant “what is that star?” answers
Price: Free with ads; small in-app purchase removes them. Verdict: The fastest way to name a bright dot in the sky, held back by a shallow database and paid extras. Best for: zero-learning-curve identification.
SkyView Lite does one thing extremely well: point your phone at a bright dot and it names the star, planet or satellite on the live camera view. It’s still updated (v3.9.2 is current) and remains among the top-rated free astronomy apps on Play. Trade-offs: a shallow database, no planning tools, and the fuller “SkyView+” features sit behind a purchase. As a companion for casual nights it’s hard to beat for simplicity.
6. Sky Map — best free offline classic
Price: Free, open source, no ads, no account. Verdict: A dependable, fully offline classic kept alive by volunteers, though the interface clearly shows its age. Best for: observing with no signal and privacy-minded users.
Yes, it’s still alive — it’s just no longer Google’s. Open-sourced and maintained by a small volunteer team, Sky Map had one of its busiest years in 2026, with releases adding a clearer ecliptic overlay, better horizon rendering and onboarding, and a new “Eclipse” build in August 2026. It works fully offline and doesn’t track you. Caveats: the UI shows its age, and there’s no deep-sky imagery. For a dependable free map, it delivers.
7. NASA App — best for missions, news and launches
Price: Free, no registration. Verdict: A free companion for missions, news, and launches, but a weak fit if you want deep-sky reference. Best for: following spaceflight alongside your observing.
Not a star map, but an essential companion. The official NASA app streams mission coverage (NASA+), posts the daily astronomy picture, and tracks launches and ISS passes over your location — handy when you spot a bright moving object and wonder what it is. Completely free, no ads. The limit for pure stargazers: little deep-sky reference, so treat it as a news and alerts layer over one of the maps above.
8. Astrospheric — best astronomy weather planner (new addition)
Price: Free; Pro subscription adds alerts, ensemble models and comet tracking. Verdict: The best astronomy weather planner on Android, though coverage centres on North America and the best features need Pro. Best for: astrophotographers planning sessions days ahead.
Most stargazing fails because of weather, not apps. Astrospheric gives hour-by-hour astronomy-grade forecasts — cloud, transparency, seeing, wind — plus a Kp index for aurora and ISS flyover times. The Android app grew fast through 2024–2026: extended cloud forecasts now use AI-nudged GDPS data, and coverage reached the UK, Ireland and Iceland in December 2025. Limitations: forecast data centres on North America plus those regions, and the best features need Pro. Nothing else on Android plans like it.
9. ISS Detector — best for spotting satellites (new addition, replacing the old “ISS Tracker”)
Price: Free with ads; Pro unlock adds Starlink trains, Hubble, planets and comets. Verdict: The most reliable way to catch an ISS pass at the right minute, and everything essential stays free. Best for: catching ISS passes at the right minute.
A 4.7-star app with 5 million-plus downloads, updated as recently as August 2026 with an AR sky-dome mode. ISS Detector tells you when the station is actually visible from your spot — dark enough and sunlit enough — and checks local weather before reminding you. Premium adds Starlink trains and Hubble. Free users get everything essential; newcomers sometimes think it’s broken because invisible passes are filtered by default.
10. My Moon Phase — best dedicated moon app
Price: Free with ads; Pro version available. Verdict: The standard app for moon phase and event timing, but only worth adding if the Moon drives your plans. Best for: moon watchers and photographers scheduling around the Moon.
If the Moon rather than the whole sky is your interest, My Moon Phase is the standard Android choice: accurate phase and illumination for any date, alerts for full, new and supermoons, and golden-hour timing. Kept updated regularly. Better at moon scheduling than any general planetarium, but only worth installing if the Moon actually drives your plans — the apps above already show its phase.
11. Light Pollution Map — best for finding dark skies
Price: Free to download. Verdict: The best way to find a dark site nearby, though some versions charge for offline areas. Best for: locating a dark-sky site within driving distance.
City glow is the real enemy of stargazing. This app overlays high-resolution VIIRS satellite light-pollution data on a map so you can find the darkest spot nearby, with Bortle-class estimates and offline caching for the drive out. It’s a Friday-afternoon planning tool, not a sky guide, and some versions charge for offline areas. Pair it with any map app above and drive to where the sky is actually dark.
How to choose
- Total beginner, just curious: Sky Tonight or SkyView Lite — free, point and identify.
- Best free full-featured map: Stellarium Mobile’s free tier, no contest.
- GoTo telescope owner or deep-sky chaser: pay for SkySafari 8 Plus or Pro; it’s where money clearly buys capability.
- Night-sky photographer: Astrospheric for conditions, My Moon Phase for moon timing.
- Satellite fan: ISS Detector. Dark-site hunter: Light Pollution Map.
- Don’t double up: Star Walk 2 and Sky Tonight overlap; pick one.
FAQ
What is the best free stargazing app for Android in 2026?
Stellarium Mobile’s free tier is the most complete no-cost option, with photorealistic rendering and accurate deep-sky data. Sky Tonight is the best free pick if you also want event alerts and comet tracking, and SkySafari’s free Basic tier is worth knowing if you plan to upgrade later.
Do stargazing apps work without an internet connection?
Some do. Sky Map runs fully offline with no account, and Stellarium Mobile Plus offers offline data packages for the field. AR-heavy apps like Sky Tonight and SkyView Lite cache core sky data after first load but work best online. Download offline maps in Light Pollution Map before driving to a dark site.
Are paid stargazing apps worth it?
For casual identification, no — the free tiers of Stellarium Mobile, Sky Tonight and SkyView Lite cover nearly everything. For telescope owners and serious deep-sky observers, yes: SkySafari 8 Pro’s database, event finder and mount control have no free equivalent, and Astrospheric Pro’s alerts save wasted trips. Where you have the choice, prefer one-time purchases (SkySafari) over subscriptions.
Can these apps control a telescope?
SkySafari 8 Plus and Pro drive most Wi-Fi-enabled GoTo mounts directly from your phone. Stellarium Mobile Plus supports NexStar, SynScan and LX200 over Bluetooth or Wi-Fi. The others are identification apps only — if telescope control matters, buy SkySafari.
Final verdict
One free app is enough for most people: install Stellarium Mobile or Sky Tonight and you can identify nearly everything in the sky. Add SkySafari 8 when your observing outgrows free tools, Astrospheric when clouded-out nights frustrate you, and ISS Detector when the station starts waving at you. Skip paid extras until a clear night proves you need them — the sky itself is still free.
