User Reviews

SynScan Pro is praised for its GoTo capability, large object catalog, and easy controls, and it can work well with popular mounts. However, stability and reliability are recurring concerns: frequent crashes/freezes, mounting/connection problems, and unreliable alignment. Users also call out a cluttered/unfriendly UI and missing features like dithering. Updates have resolved some issues for some devices, but consistency across Android versions and hardware remains a common complaint.

Pros

GoTo feature with a large object catalog and searchable lists
Easy-to-use UI and intuitive controls
Good mount compatibility with AZ-GTi and Star Adventurer GTi when connected
Helpful built-in features like Tonight's Best and object listings

Cons

Frequent crashes and freezes across many reviews (crashes, unresponsive UI, white screens)
Connectivity and pairing problems with mounts and WiFi adapters (can't connect or communicate)
Alignment reliability issues (polar alignment and two-star alignment can be flaky)
UI/UX issues (unintuitive UI, poor documentation, visual glitches like black-on-black text)
Missing dithering option for shutter/DSLR control (requested by users)

Recent reviews

Version 2.4.31 fixes the "negative response" error introduced in previous updates. Even the Pro version is very limited in it's functionality, but it does what I need it to. UPDATE 2026-03-09 v2.6.10 on Android 16. Sideloaded FITS files because the built-in downloader often fails, but files downloaded so far remain, taking up space, but without purpose. After a while, FITS files are auto-deleted. We need a way to direct SynScan to a User folder where the FITS files for auto align can be stored.

I'm leaving a 5 star review to hopefully offset some of the lousy reviews here. Is it a 5 star app? No. A weak 4 star app, but I have no connectivity issues. It does exactly what it's supposed to do. It's just terrible at context switching. If I want to open something else for astronomy on my phone, there's about a 50/50 chance the app will stay responsive. Half the time, it has crashed when I get back to it. Edit: updating the app lost planetary alignment to knock off 1 star. Bring it back!
