GPS Altimeter & Barometer

Altimeter gives you a large, live altitude readout from GPS or your device barometer, so you can check where you are at a glance and keep moving.

Whether you are hiking a ridge, driving through mountain passes, riding a lift, or just curious about the floor you are on, elevation is easier when the number is big, clear, and ready when you need it. Altimeter keeps the important details close: current altitude, session min and max, change rate, signal strength, and the source of your reading.
