Pressure Altimeter Tracker2.35 - App Store

AltiTracker runs automatically in the background and keeps track of altitude changes in real time. The app's interactive graphs let you see and explore altitude changes and trends over time.

With our Live Activities feature, AltiTracker shows your current altitude even when you phone is locked.

You can select either sea-level operation or a relative altitude mode that tracks your altitude relative to a selected reference altitude (for example, your altitude relative to your base camp).

Optional CSV export/import capabilities let you save your altitude data at ultra-high one-second resolution, and you can explore previously saved CSV altitude data directly in the app.

The included Watch app can run stand-alone on your Watch fully independent of your iPhone. Our Watch app also let you easily adjust all key settings such as reference pressure or relative altitude.

Real-time stats let you track your total climb/descent info, min/max altitude, vertical speed, and direction.

You can set your sea level altitude or pressure manually, or use the GPS feature to obtain a reference altitude automatically.

Our Live Background feature helps ensure that you maximize battery life by automatically turning off operation after the desired background runtime period.

And our climb sensitivity feature helps minimize the classic problem of weather-based altimeter "drift" between active climbs.

For mariners, our app can even estimate wave height and distance between waves.

And for good measure, we included our NOAA/ICAO station-based weather data along with our amazing wind speed analyzer.

As you can see, we set out to build the most advanced pressure-based altimeter app out there and we hope you give it a try!

Version History Fixed bugs with language detection. Added an option to manually select the language used in the app in the options screen. Changed some of the wording to help with translation to other languages, and fixed some UI layout bugs related to translated text. Fixed bug with min/max symbols being swapped for "displayed altitude" values on the altitude screen. 2.35 May 8 Added in-app translation for languages supported by Apple's Translate technology. Updated UI elements where possible to be language-neutral. 2.34 Apr 10 Bug fixes and internal performance improvements. 2.33 Feb 24 Fixed remaining issues with the app's Live Activity feature. Fixed a related issue on the Watch that caused background operation to continue when not desired. Reconfigure the Watch's background operation option to be easier to use and made it distinct from the related Live Activity feature on the iPhone app. Fixed issue with resetting altimeter stats on the iPhone and Watch altimeter screens. 2.32 10/03/2025 Added notification capabilities for NOAA/ICAO weather station conditions and forecasts. Fixed Live Activity compatibility issue with iOS 26. Fixed issue with weather data not being available due to NOAA API changes. 2.31 09/22/2025 Fixed issue with settings screen not initializing correctly. 2.21 02/15/2025 Revised complications and widgets, compass support, and UI enhancements. 2.2 02/08/2025 Added launch screen and fixed issue with Live Actives background updates. 2.11 08/30/2023 Added support for Live activities and mm/mercury pressure units. 2.10 08/24/2023 2.0 08/10/2023
