This app freezes and crashes on me regularly. It’s frustrating when you are trying to image or when you’re just observing. Press the arrow to slew and it lights up and freezes. Then after it freezes it just crashes and I see my home screen. It crashed on my multiple times tonight in a matter of minutes. I wanted to scream!
The other thing I don’t like, idk if this is normal behavior for a go to, when I center a target I see some of the arrows blinking in the opposite direction I just moved to center my target. The blinking arrow is then effectively moving the mount and taking me off target. Is this a function that the computer believes it is keeping the target centered? Why wouldn’t it just stay and sidereal track from where I positioned it?
I’m running this on an iPhone 11 Pro. This is a recent model and shouldn’t have trouble running such an app.

Nice layout but crashes!

When using the down arrow for slewing, the app often crashes and you have to start all over which often loses the target in the eyepiece. Come on devs…..two years? This hobby is growing quickly so don’t get left behind by poor functionality.

Great concept - needs more work

I recently bought the Skywatcher AZ-Gti mount which is exactly what I needed Foran easy travel mount.

This app works well with the mount but the position of the moon is always incorrect. The app shows the moon below the horizon when it is high in the sky.

If you fix this I will happily give the App 5 stars.
