I made the mistake of scanning the QR code that was on the left which failed. Then I noticed the silver QR code which I scanned and activated. You can only activate on 5 devices. So because of this limiy, I am removing a star. The app itself with the AR is nice. BTW using Samsung Note 20 Ultra. Will update after the sky clears up and put this to the test.
★★★★★
When trying to open the app it goes black with a music in the background and nothing happens
★★★★★
Got it to work! I couldn't get the original activation code to work, so I reached out to the Developer. They sent me a new code that worked. The app itself uses the phones compass and GPS. It is handy for orienting in unfamiliar places. I plan on using this app for my other telescope for finding north. This is infact a very simple app, but it seems very stable. I've experimented with other planetariums and compass apps that drift so bad they're worthless. I would give this 10 stars if I could.
★★☆☆☆
This app does not work after pressing start seeking it shows Bluetooth search option and after pressing that it just stuck showing searching the only thing I like is that we can learn constellation from it.
★★☆☆☆
Says that the activation QR code in the manual is invalid. No way to use the app without it. What a joke of an app.
★★☆☆☆
Qr doesn't work. Neither does trying contacting through email. The telescope is nice / app sucks

Trust & Safety: AR Telescope-3L requests location (foreground and background), network, Bluetooth, camera, and storage permissions typical for AR apps. These enable sky-based AR features but raise privacy considerations; the presence of a leak_location dev-flag suggests monitoring data handling and clear privacy disclosures are recommended.
