Altimeter: at a glance

• Altitude information as desired — Displays elevation in meters, feet, meters+feet, or feet+meters, including measurement accuracy (for those who want to know exactly).
• Versatile coordinate systems — Location display in WGS, Swiss coordinates, UTM, and MGRS (because mountains don't stick to one system).
• Save waypoints — Save your current location as a waypoint with a name, icon, and color (personalized treasure map).
• Set waypoints manually — Place points directly on the map or add them by entering coordinates (for planners and spontaneous explorers).
• Navigate to waypoints — Get reliably guided back — even when your sense of direction takes a break.

Altimeter: on your Apple Watch

• Synchronization — sync your waypoints with your iPhone
