Couple recommendations

This is easily the best altimeter app but I’m not sure it is being supported. It would be nice to see an updated version (no updates in 3+ years)

Would like to be able to use it in iOS live activity so I can see it when my iPhone locks.

I love the app when I can read it (which is most of the time) when it is bright outside it is difficult to read. The dark background is the only option. that allows you to change from black to white.

Nice app.

Needs to self calibrate using gps automatically. The watch app asks me to enter the correct elevation every 24 hours. That's why I opened the app! I want to know the elevation not tell some app what the elevation is! As it stands I have to use another app to tell this app what it's elevation is. :( also PLEASE support inches of mercury for US customers. Consider changing the calibration to known mmHg/inches since we can gain this data locally. Thanks for the great app!

Most accurate altimeter I've found

Been using my Watch for altitude information when flying my ultralight aircraft and found other GPS altitude apps to be completely inaccurate and not precise at altitude. Using the barometric function with Altimeter+ has been incredibly accurate. I used it for a flight this morning and 15 hours later at a known elevation, I'm basically right on with the baro altimeter.
