Altimeter: Height & GPS

See your altitude and barometric pressure from the device sensors.

See exactly how high you are — live altitude, barometric pressure and oxygen level, straight from your iPhone's sensors and GPS.

This app turns your phone into a precise elevation gauge for hiking, cycling, flying a drone or just checking the height of where you stand. No signal? No problem — the barometer works fully offline.

WHAT YOU GET

• Live altitude from GPS and the built-in barometer
• Real-time air pressure in hPa with a clear conditions band
• Oxygen level estimate for high-altitude awareness
• Record a climb and see gain, peak and every point on the way up
• Compare your height to Everest, Ben Nevis, Mont Blanc and more famous peaks
• Atmosphere reference: pressure and oxygen at every elevation
• Switch between metres and feet in one tap

HOW IT WORKS

1. Open the app to see your altitude instantly
2. Tap Start Tracking before a hike or climb
3. Stop to save the track and review it any time

UNLOCK EVERYTHING Track unlimited climbs, keep your full history and export your data with Pro — available as a weekly or yearly plan, or a one-time lifetime purchase.
