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).
AltiTracker runs automatically in the background and keeps track of altitude changes in real time.
Our Watch app also let you easily adjust all key settings such as reference pressure or relative altitude.
With our Live Activities feature, AltiTracker shows your current altitude even when you phone is locked.
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.
