The 5 Best Stargazing Apps to Identify Stars in 2026

In this guide we compare the 5 best astronomy apps in 2026.
Apps for identifying stars, planets and constellations
Star map apps for your phone that identify stars, planets and constellations as you point at the sky, with deep-sky catalogues, event alerts and night mode.

Sky Tonight tells you what is worth seeing tonight from your location and guides you to the object with arrows instead of leaving you to search on your own.

Pros
- Calendar of what's visible each night
- Guides you with arrows to the object you want
- Very well rated by users
Cons
- Full features require a subscription

- Alerts for visible astronomical events
Cons

SkyView Lite overlays the constellations on the camera image with drawings of the mythological figures, with no sign-up and no connection needed.
SkyView Lite is the simplest of the lot: point your phone at the sky and it overlays the names of stars, planets and constellations on the live camera image, complete with drawings of the mythological figures. It needs no account and no connection, and it is ideal for showing a child the night sky.
Pros

TopApps analysis
Sky Map is open source, ad-free, sign-up free and very light, ideal for older phones or for anyone who does not want to hand over any data.
Sky Map was once Google's star map and is now an open-source project: free, ad-free, no sign-up and no unnecessary permissions. The interface is plain and the catalogue basic, but it does the job perfectly if all you want is to identify stars and planets with the naked eye.
Pros
- Completely free and ad-free
- Open source, with no data collection
- Very light, runs on old phones
Cons
- Basic catalogue compared with Stellarium
- Dated interface
- Development moves very slowly

Frequently asked questions
Which is the best free astronomy app?
Sky Map is the only one that is completely free, with no ads and no paid version, though its catalogue is basic. Stellarium offers a great deal of content in its free version and is the most complete of those you can use without paying. SkyView Lite and Star Walk 2 are free but carry ads and reserve content for the paid version.
Do these apps work without an internet connection?
Yes, and it matters, because the best skies are usually where there is no signal. Stellarium, Sky Map, SkyView and Star Walk 2 work offline once downloaded: they use the phone's GPS and orientation sensors, not the internet. Only extras such as object photos or event alerts need data.
Are they useful with a telescope?
As support, yes. Stellarium and Sky Tonight let you simulate your telescope's field of view and plan what to observe each night, which is exactly what you need before heading out. Pointing the telescope automatically requires a compatible motorised mount; some of these apps can control one, but that depends on your equipment.
Why does the app show a star where I see nothing?
Almost always light pollution: from a city you only see the brightest stars, even though the app shows thousands. Many catalogue objects, such as galaxies and nebulae, are also invisible to the naked eye and need binoculars or a telescope. Sky Tonight is the best at filtering what is genuinely visible from where you are.
