**Currently only supports airports in the United States as well as typical USA units (pressure in inHg, altitude in feet)**

Fast, simple, works

Works as advertised with no backend exploitation of location data!!


Altimeter setting is always wrong

This app works, but the altimeter setting is rarely correct which makes the altitude information incorrect. Checking the current METAR for the closest airport often shows altimeter settings vastly different than what the app claims, even if you repeatedly refresh. The data it uses is hours old at newest, and it will not let you manually input the altimeter setting of the closest airport. Don’t get this app until it’s fixed!
