Pressure Altimeter Tracker

Continuous real-time altitude tracking with a Watch app, Live Activities, altitude alerts, vertical speed, data export, aviation weather, and interactive altitude graphs.

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!
