Altimeter Pro GR

Altimeter Pro GR turns your iPhone into a clear, easy-to-read altimeter and companion for outdoor use. See your current altitude, vertical accuracy, latitude and longitude (with degrees/minutes/seconds), and a live compass-style heading. Weather data adds temperature and atmospheric pressure so you can read conditions alongside elevation.

Switch between imperial and metric, pick your preferred language from Settings, and open the Pro dashboard for session-focused metrics (pressure, vertical accuracy, max altitude this session). Pro detail can be unlocked with a short rewarded video for 24 hours.

Share your position when you want to, manage units and language from Settings, and review Terms of Use & Disclaimer in your language. Built for hikers, pilots, travelers, and anyone who wants altitude and context at a glance—not for aviation or safety-critical navigation.
