Altimeter vs Altitude Measure

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 — 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 — then start tracking your next climb.

Know exactly how high you are. Altitude Measure turns your iPhone into a precision altimeter. It combines GPS with your device barometer to show your height above sea level, accurate to a few metres and steady enough to trust. WHY TWO SENSORS GPS knows where sea level is, but its altitude reading drifts by ten metres or more while you stand perfectly still. A barometer is precise to the centimetre for changes in height, but it has no idea where sea level is and wanders with the weather. Altitude Measure anchors one to the other. You get the absolute reference of GPS with the steadiness of the barometer, so the number stops jumping around when you are not moving. WHAT YOU SEE - Your elevation above sea level, in feet or metres - A live elevation trace as you climb or descend - Vertical speed, air pressure and raw GPS altitude - Oxygen level, standard temperature and the boiling point of water at your current altitude - Altitude sickness advisories above 2,500 m SEE WHAT YOUR NUMBER ACTUALLY MEANS A number on its own does not tell you much. Altitude Measure places you on a scale against the clouds, the Eiffel Tower, the Burj Khalifa, Mont Blanc, Aconcagua, Everest and a cruising airliner. You will know at a glance whether you are standing higher than the tallest building on earth, and how far you still are from the top of the world. EXPLORE 115 PLACES, WITH NO SIGNAL Browse the highest cities on the planet, famous summits and the lowest places on land. Find which of them sits at your exact height right now. Every place is bundled inside the app, so search works on a ridge with no bars. SAVE WHERE YOU HAVE BEEN Keep any reading together with its coordinates, air pressure, place name and the last few minutes of your climb. Review your records, your highest and lowest points, and how your elevation has trended over time. CALIBRATE FOR REAL ACCURACY Standing at a trailhead sign, an airport or a summit marker with a published elevation? Enter it and the barometer locks on for sub-metre precision. You can also set the local sea level pressure (QNH) by hand, the same figure airports publish every hour. BUILT FOR Hiking and trail running. Mountaineering and climbing. Flying, gliding and paragliding. Cycling and skiing. Road trips over mountain passes. Scuba divers checking altitude before a dive. Anyone who simply wants to know how high they are right now. PRIVATE BY DESIGN Your saved measurements and your location history stay on your iPhone. There are no accounts, no analytics and no advertising. REQUIREMENTS Location access is required. A barometer gives full precision and is present on iPhone 6 and later. Without one, the app falls back to GPS only and the reading is less stable. ALTITUDE PRO Pro unlocks unlimited saved measurements, precision calibration and export. Altitude Pro is offered as a weekly auto renewing subscription or as a one time lifetime purchase. Payment is charged to your Apple Account at confirmation of purchase. A weekly subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period. Manage or cancel your subscription in your Apple Account settings at any time.
