Your altitude — accurate to the meter

Altitude combines GPS with the barometric pressure sensor of your iPhone and merges both values through intelligent sensor fusion. This keeps the altitude significantly more stable and accurate than pure GPS measurement, even in changing conditions.

Yes. In GPS mode, Altitude measures your altitude even without an internet connection — no signal, on a mountain, or in airplane mode. An active connection only improves automatic calibration, but is not required.

Altitude is free on the App Store and is supported by ads. If you want to measure without ads, you can upgrade to Altitude Premium — for a focused, distraction-free experience.

With Premium, you use Altitude completely ad-free. You get the same precise altitude measurement experience — just without ads and without distraction.

Yes. Altitude automatically adapts to your system language and currently supports German, English, French, Spanish and Portuguese.

For anyone who needs reliable altitude readings: hiking, mountaineering, cycling, drone flights or travel by air. Wherever precise altitude above sea level matters — even without signal.
