Verdict
The serious one. A real catalogue, proper observing tools, and the app amateur astronomers actually point their telescopes with.
Best for
Someone who owns a telescope and plans a night before going outside.
Dealbreaker
Buying it once is not the end of it — twelve of the last two hundred reviews are from people who found a newer version waiting behind another payment, and several say the one they bought stopped being supported.
The facts.
Pulled from the App Store, not written by hand.

Where we recommend it
Stargazing apps you buy once ›Sky maps and planetarium apps that charge once instead of monthly, each with its catch.
Alternatives with the same rule.
Every app here is a single purchase. None of them can start charging you monthly for what you already bought. Also with a catch.

Verdict. Point it at the sky and it tells you what you are looking at. That is the whole app, and no other one here does it with so little in the way.
Best for. Someone standing in a garden who wants to know what that bright thing is, tonight, without a tutorial.
Dealbreaker. Identifying is all it does. There is no observing planner, no telescope control and nothing like the depth of catalogue the bigger apps carry — outgrow it and you are buying twice.
$2.99 once · 4.7★ (67,163) · Updated Aug 10, 2026
Verdict. The prettiest of these by some distance, and the one most people already own. Costs less than a coffee and looks like a planetarium.
Best for. Anyone who wants stargazing to feel like an occasion rather than a lookup.
Dealbreaker. Five of the last two hundred reviews call it hard to find your way around, and others say the notifications cannot be turned off once they start.
$2.99 once · 4.7★ (7,296) · Updated Dec 28, 2023
Verdict. Not a sky map at all — a three-dimensional model of the solar system you can fly around and wind forwards through time.
Best for. Explaining orbits to a child, or to yourself, rather than finding anything overhead.
Dealbreaker. It will not help you identify what is above you tonight, and reviewers report parts of it sitting behind a further subscription despite the purchase.
