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. SUMMIT BOOK & ASCENT ACCOUNT Every climb is booked: your ascent account shows this year and all time, translated into mountains up to Everest. • Stamps in your summit book for altitude, endurance and special tours – retroactively, too • New personal records after every tour • Your mountain year in review, on three cards • The backup takes it all to a new phone – even to Android SHARING • A tour as an image – elevation profile and numbers on one card • Summit photo with your elevation gain on it, in three designs (Logbook, Profile, Stamp) – as a post (4:5) or story (9:16), without the location in the photo data (Pro) • Your mountain year as three story cards (Pro) TRY PRO FREE FOR 7 DAYS For seven days after installing, every Pro feature is unlocked — no purchase, no payment details, no account. After that the free features remain. 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, waypoints, distance, elevation gain 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. 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.

Have you climbed to the top of a mountain and want to know your current elevation? Or are you out and about and wondering how far you still have to go? Altimeter shows you your elevation. It’s also conveniently available on your Apple Watch! What if you want to mark points along your route so you can find them again later? No problem! With Altimeter, you can name and tag locations with an icon and navigate back to them later. This works on your iPhone, iPad, and Apple Watch. Altimeter is free, ad-free, and doesn’t track you in any way. Some features are available only to supporters, but anyone can try them for free for a few days. The basic features are freely available and will remain so. If you have questions or comments, you can submit a support request within the app. Features - Elevation in meters or feet with high accuracy - Locations in multiple coordinate systems (International, Swiss, UTM, MGRS) - Save locations as waypoints for later and organize them into folders. - With Augmented Navigation, you can see exactly where your destination is right in the camera view. - The Radar view shows you all waypoints in your vicinity, even in 3D. - Share your waypoints even without an internet connection. - The combined view shows you elevation and location at a glance. - Light/Dark Mode, color or monochrome - iPhone, iPad, and Apple Watch Altimeter uses your device’s GPS chip to determine your elevation and location. To maximize battery life, the chip is only activated when the app is open on your iPhone, iPad, or Apple Watch. This means there is no background activity, and your location is not stored. Note Accuracy depends on GPS satellite reception. Reception is limited indoors. Continuous use of GPS can significantly reduce battery life.
