Stellarium Mobile Plus stands out for its documented offline catalog and observing tools; SkySafari is worth considering for telescope-focused features; and Star Walk 2 is presented by one comparison guide as a beginner-friendly option. Before paying, check the exact features, device platform, and telescope compatibility you need.
How to choose a premium stargazing app
Start with the job you need the app to do. For casual sky identification, ease of use may matter more than a huge catalog. For planned observing, look for event-finding and session tools. For telescope use, confirm that the app supports your specific mount and connection method rather than relying on a general claim of telescope control.

- Quick identification: prioritize a clear sky view and straightforward object discovery.
- Learning: choose an interface that helps you explore and understand what is overhead.
- Planning: look for observing-session features, calendars, and event finders.
- Telescope control: verify the app’s supported protocol, your mount, connection method, operating system, and app version before purchase.
- Remote observing: check the current offline behavior of the specific app and features you intend to use.
These are different needs, not a single objective ranking. A comparison guide labels SkySafari 7 Pro “Best overall” and “Best telescope control,” Stellarium Mobile Free “Best free,” and Star Walk 2 “Best for beginners”; those are the guide’s editorial judgments, not independent test results. Read the comparison guide.
What the premium apps add
| App | Documented strengths | What to verify |
|---|---|---|
| Stellarium Mobile Plus | Stellarium Labs lists telescope control through the Stellarium Telescope Server protocol, ocular and instrument simulation, observing-session tools, an event and satellite-pass calendar, and 3D views. Its product page states that the app works offline with a reduced catalog. | Confirm that your mount supports the stated protocol and that your chosen features and device work as expected. |
| SkySafari 7 Plus | The US App Store listing describes telescope control, a space simulator, and an Events Finder. | Check the current listing for your device and region, and confirm mount compatibility. |
| SkySafari 8 Pro | The publisher describes telescope-related capabilities, StarSense Explorer integration, and event finding. | Distinguish the app purchase from SkySafari’s separate Premium membership; confirm which features require recurring access. |
| Star Walk 2 | A comparative guide characterizes it as a friendlier starting point for beginners. | The available source material does not establish a detailed official premium-feature matrix, so verify the current app listing before buying. |

Stellarium Mobile Plus: useful when offline planning matters
Stellarium Labs says its app works without an internet connection, but the offline catalog is reduced. The company lists an online catalog of over 1.4 billion stars and over 3 million deep-sky objects, and an offline set of 2.5 million stars, 2.9 million deep-sky objects, and 10,000 asteroids. These are vendor-stated catalog counts, not independent measurements. The page also lists Plus features including session tools, a calendar for events and satellite passes, ocular simulation, 3D views, and telescope control through the Stellarium Telescope Server protocol. See Stellarium Labs’ feature and catalog details.
Offline access is particularly relevant if you observe somewhere with unreliable connectivity. However, do not assume that every app feature—or every competing app—works offline. Check the current documentation for the functions you plan to use.

SkySafari: distinguish app versions from membership
SkySafari’s listings describe features across different app versions, so confirm the exact product before checkout. The US App Store listing for SkySafari 7 Plus describes telescope control, a space simulator, and an Events Finder. It showed $9.99 when captured; that is a US iOS storefront snapshot, not a guaranteed current price in every region or a recurring price.

Star Walk 2: a beginner-oriented option, with tier details to check
A comparison guide positions Star Walk 2 as a friendlier starting point for beginners, while emphasizing SkySafari Pro for telescope use. That is the guide’s characterization, not a verified feature-by-feature assessment of Star Walk 2’s paid tier. If you are considering it, inspect the current listing for the features, platform, and payment terms you need rather than assuming the premium version includes a particular tool. See the comparison guide.
Before buying for telescope control
“Telescope control” is not a promise of compatibility with every telescope or mount. Stellarium Labs specifies support through the Stellarium Telescope Server protocol. The available SkySafari descriptions mention telescope-related capabilities, but do not establish a complete current compatibility matrix for either app.

- Find your exact telescope or mount model and determine how it connects to your phone or tablet.
- Check the app’s current compatibility documentation for that model, protocol, and connection method.
- Confirm the app version and operating system required for the feature.
- Check whether the control feature is included with the app or depends on a separate membership, accessory, or setup.
- If compatibility is unclear, ask the app publisher or mount maker before buying.
What the available comparisons cannot establish
The cited product pages and editorial guide do not provide a common hands-on test of image quality, sensor accuracy, battery use, or performance. Nor do they establish a complete, current feature and device-platform matrix across all four apps. Treat rankings as recommendations for particular use cases, not proof that one app performs best for every observer. Prices, tiers, platform availability, and compatibility can change; check the live listing for your region and device.
