Seems useful but I can't find any way to have it use my phones GPS location - it has to be I put in manually. It's good to be able to override the default, but my phone knows where it is why doesn't an app running on the phone know it? There's a Locate button but it doesn't work on Android 10 (Pixel 4) Also what I really want is sun and moon meridian passage and altitude at MP.

Fantastic app. Every component works. Only annoyance is the time changes to Local instead of UT1 when you enter a new time. But a few clicks and all is OK. Update...Even better now with the April 2020 update. Date and time are UT1. I love it.

Displays a lot of useful info in a clear, easy to read format. Excellent features for celestial navigation. Small size. Well done.
