Useful for finding your stellar bearings

This app helps me to find at a glance both planetary bodies and the names of visible stars in my area. It works very well to help me get my bearings. My vision isn’t as good as it once was and having this tool makes it enjoyable to view the stars and planets, many like Mars, Jupiter, Saturn, and Venus can be seen with the naked eye.

Super fun! :DSuper fun! :D

Compass spins around - no support

The compass doesn’t point in the right direction. There is no way to contact the developer. Total waste of money.
