Altimeter
Read full descriptionHide full description
See exactly how high you are. AltiMeter reads your live altitude, barometric pressure and oxygen level straight from your iPhone's built-in barometer and GPS โ an instant, accurate elevation gauge in your pocket. Most altitude apps stop at a single number. AltiMeter turns your phone into a full climb companion: record a hike or ascent, watch your gain and peak build in real time, then review the elevation profile of every trip. And because the barometric sensor needs no signal, your altitude keeps reading even deep in the backcountry with no cell service. WHAT YOU GET - Live altitude from GPS and the built-in barometer, updated as you move - Real-time air pressure in hPa with a plain-language conditions band - Oxygen level estimate so you can gauge thin air at high elevation - Record any climb and capture gain, peak, ascent, descent and range - Compare your height to Everest, K2, Mont Blanc, Fuji and more famous peaks - Atmosphere reference chart: pressure and oxygen at every elevation, meters or feet PERFECT FOR - Hikers and mountaineers tracking elevation on the trail - Cyclists and trail runners logging total ascent - Drone pilots and skiers checking altitude before takeoff or a run - Anyone curious how high their town, hotel or lookout really sits WHY NOT JUST CHECK THE BUILT-IN COMPASS? The Compass app shows one static altitude and nothing else. AltiMeter reads live pressure, estimates oxygen, records your whole climb as a chart you can revisit and export, and works offline through the barometer when GPS drops out. PRIVACY Every reading stays on your device. No account, no ads, no tracking. FULL ACCESS AltiMeter is free to see your live altitude, pressure and oxygen. Go Premium to record unlimited climbs, keep your full session history with detailed stats, and export any track to share or log. Premium is offered as a weekly or yearly subscription, or a one-time lifetime purchase, unlocking every feature the moment you upgrade. Open AltiMeter and read your altitude in one tap โ then start tracking your next climb.

Verdict
The clearest difference is in-app purchases: MAI Smart at none against Altimeter's 3. Altimeter's advantage is update cadence (every 4 weeks vs every 3 months). On price, ads, device support and iOS requirement there is nothing between them.
