I'm a longtime user of the pc version and the predecessor of this app. While this app is really great, I am missing one option: It would be great if it was possible to switch off the labels entirely. While the labels are nice I would like to switch them off at times, for example to display the 4 big Jupiter moons as they appear in my binocular: without labels. Also I am missing the many pamorama views from the previous version as well as the acoustic background options.

Edit: actually the "Follow Sky mode" keeps turning itself back on constantly, often very stubbornly. Its very annoying and is making the app pretty much unusable now. Its pretty good. Although its not all as intuitive as the old computer version was. Plus it seems to randomly unlock a target and using the accelerometers on the phone. Might just be me misusing it, though

It's 5 star when it works. It takes spells where it doesn't recognize my phone having a digital compass therefore not allowing me to use the follow Sky feature. Developers please fix this issue. I guess I'm going to have to uninstall it again and go back to Mobile Observatory until this issue is fixed period paid $10 for this and it keeps breaking itself
