Works well

I haven’t used all of the functions, but so far it works well for doing azimuths/aplitudes, star fixes, sun lines, and getting true wind direction. For the price it has been worth it for me.

Save your money

Unfortunately this is a home made app with a barely usable interface. The idea is nice but the cost of purchase is simply not worth it. If it was free I would consider it but since I paid I can only regret having done so.
