Accurate Altimeter Free

About Accurate Altimeter Free Android App

This altimeter works online or offline. It estimates your elevation with three different methods:
- Using GPS satellites triangulation. No internet connection required, quite accurate with clean sky but works only outdoors and it's slow.
- Using the ground elevation at your current position. Accurate but require internet connection and works only if you are at ground level.
- Using the pressure sensor of your device (if available). If it's available internet connection it calibrates itself on the nearest weather station pressure to improve accuracy.

Detect an elevation with marker on Google Map then collect and save it.
