Comments on SynScan Pro for Android

★★★★★ Benjamin Green · Jun 3, 2025
I'm sorry others have had issues but my experience as a visual observer with the app and my AZ-GTi(X) has been nothing but positive. I've never dropped Wi-Fi, even when I've switched to Sky Safari to view the sky map. The "Tonight's Best" works better than Safari as it shows Alt/Az degrees for everything listed, so you needn't waste time trying to point at objects obscured by trees or clouds. It used to be that it made nicer with Android than iOS, but I understood those problems were solved.
★★★★☆ Guy Zumpetta · Aug 26, 2022
Android app deserves a much better score than shown here. App has gone through several updates and fixes. I used the hand controller that came with my Sky Watcher scope until recently, when I gave the Android app another try. I now rely on the app almost exclusively. Alignment is easier and there are more choices for alignment method. Wireless connection eliminates being tethered to the mount by a coil cord. Downside is a smartphone screen lacks tactile feedback, but practice helps.
★☆☆☆☆ Phil Black · Sep 19, 2024
Pixel phone running Android 14 connects fine to AZ-GTI mount Wi-Fi but frequently freezes and locks up. Only way to recover is to close the app which loses all alignment, total pain. I have noticed this seems to be related to using the search function when selecting stars, works ok initially but becomes unresponsive after second or third attempt. Also, white screen flashes between app screens. Just not good enough.
★☆☆☆☆ Futureairways · Jun 30, 2024
When I press polar align the app crashes? It didn't do that before the update.
★☆☆☆☆ Jonathan Shields · Mar 2, 2023
Won't connect to my telescope at all on my Samsung S20. Luckily the standard Synscan app works fine.
★☆☆☆☆ Jeff Jones · May 28, 2023
Polar Scope no longer lights up, so makes it awkward to polar align on star adventurer gti
