Your outdoor altitude computer. Offline, no ads, no tracking. Now Altimeter shows your altitude large and instantly — and does more: record tours, read air pressure and weather trend, calibrate your altitude to within a few metres. On your iPhone and on your wrist. This app collects no data about you. No account, no sign-up, no advertising. FREE FEATURES • Live GPS altitude in meters or feet • Coordinates in DMS, Decimal Degrees or UTM format • 6 stunning background photos — mountain, waterfall, forest & more • Home screen widget (small, medium & large) • Record your first 3 tours — with map, elevation profile and GPX export • Accuracy readout: you can see how reliable the altitude currently is NOW ALTIMETER PRO Take your outdoor adventures further with Pro: Barometer & Weather Trend Live air pressure in hPa with a 1-hour history chart. Know whether the weather is improving or deteriorating before you feel it. Trend indicators and a detail view with min/max/delta statistics. Altitude Calibration Tap the altitude and enter a value you know — a summit marker, a trail sign, your own address — or the QNH from a weather report. The app then works barometrically and shows altitude to within a few metres instead of the 10 to 30 of plain GPS. Climb and Descent Rate Vertical speed in m/min or ft/min, right next to the air pressure. The number ski touring, mountaineering and paragliding actually think in. Compass Real-time heading display with a rotating arrow. Always know which direction you're facing.
