After flight, the recorded altitude data is downloaded to your mobile device, where you can view, annotate, and share with friends. For certain sports it also records acceleration up to 24G in three dimensions so that you can analyze your flights in even greater detail.

App Required

AltimeterThree requires a smartphone or tablet with Bluetooth™ running the AltimeterThree app from the Apple, Amazon, or Google Play app stores.

We suggest you install the app before purchasing the altimeter, to make sure your device is compatible.
