Altimeter - New App for iOS, Android and the watches
This altimeter either uses GPS or the built in barometer (if available) to determine your current elevation on earth. While GPS provides the absolute altitude as long as you see the sky it is not very accurate. With the help of the barometer we can calculate the altitude indoors and outdoors with a much higher accuracy. But we need a reference altitude to calibrate the barometer altitude. This calibration will degrade over time as the air pressure changes with the weather.
Available for:

iPhone, iPad and Apple Watch

Android phones, tablets and Wear Watches

Free version for Android phones and tablets
Features:
- GPS and barometer based altitude
- set a base altitude as starting point and get the altitude difference (e.g for hiking or biking)
- calibrate the barometer altitude (connect the current air pressure to your current altitude)
- calibrate with the help of GPS, the standard sea level air pressure or to any altitude you want
- time difference to the last calibration
- warning when it is time to calibrate
- switch between metric and imperial units
The Apple Watch App
By running Altimeter on your Apple Watch you have the current altitude always on hand without taking out your phone. You can choose between GPS and barometer altitude. For a quick direction you can use the glance view.The Wear App
By running Altimeter on your Android Wear watch you have the current altitude always on hand without taking out your phone. You can choose between GPS and barometer altitude.By setting Altimeter as your watchface you have the altitude always on hand when you activate your watch (without loosing the ability to read the time). Just flick your wrist.
