Stargazing apps you buy once.

Buy GoSkyWatch Planetarium. Hold it up, and it names what you are pointing at — no setup, no account, no menus to learn. Star Walk 2 Pro is prettier and cheaper still if you want the experience rather than the answer. SkySafari is the one to get if you own a telescope, though read its catch first. Solar Walk 2 is a different thing entirely: a model of the solar system, not a map of tonight's sky.

GoSkyWatch gets consistent praise for a clean, uncluttered interface and for accurate real-time tracking of celestial objects like comets and near-earth objects. Reviewers who've used it for years call it a keeper, not just a novelty they installed once.
Best for
Someone who wants to point their phone at the sky and identify a star or planet on the spot, and who also wants to track specific events like comet passes or NEOWISE-style sightings.

SkySafari

Simulation Curriculum Corp.
View on the App Store ›
$6.99 once4.7★ (17,923)Updated Sep 1, 2026
Verdict
SkySafari is easy to use and well-liked for its interface, but the review pattern shows a real tension: many buyers hit in-app pop-ups, promos, and even subscription prompts for features beyond the base purchase, despite this listing being a one-time charge.
Best for
Someone who wants a simple, easy-to-navigate stargazing app for casual sky-watching and doesn't plan to chase upgrades or premium tiers within it.
The catch
Multiple reviewers report in-app promos, upgrade nags, and even subscription paywalls for extra features layered on top of the initial purchase.

Solar Walk 2 - View Planets 3D

Vito Technology Inc.
View on the App Store ›
$2.99 once4.7★ (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.
The catch
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.

Who should skip this entirely.

There are good free sky maps, and if you only look up two or three times a year one of those is plenty. Skip all of these if what you actually want is to see more rather than to name more — no app improves the view, and the money is better spent on a cheap pair of binoculars, which will do more for you on a dark night than any of this.

Questions.

Do these work without a signal?Mostly yes — the star catalogue is on the device and the position comes from the compass and GPS. Live satellite passes and event data need a connection.
Will one of these control my telescope?SkySafari does, at its higher tiers. The others identify and plan only.
