1. Gps location teardrop icon upon touching it will display a message that it's locating but no further location info appears on main screen.
2. Pulls other weather data on 2nd screen from a service, but does not share what is the source of that data.
3. App will read the barometer built into your phone if you go to settings and select internal sensor.
4. + and Pro buttons will take you to Google Play.
5. This app could get another star if it was clearer what the GPS location teardrop icon does.App won't allow me to Enter Locations; but, instead, Demands to Utilize "Location"; WHICH, Uses Battery Power that I Cannot Afford to Use.Pretty basic - mostly an ad for other apps.Not working with this devices internal.
