Altimeter for Wear OS Android is a precise barometric altimeter app and watchface for Wear OS smartwatches. The app can run as a normal app, watchface, or complication in other watchfaces. It allows you to view your current altitude and vertical speed on your watch, and share altitude recordings. The app also features automatic altitude recording, graph view, minimum and maximum altitude recording, precise recording of rise and decline, and automatic calibration using current weather data.

The full version of the app includes additional features such as graph display on the watch, open recent altitude recordings from history, and full customization options. The app is compatible with all Wear OS smartwatches, including Sony SmartWatch 3, Fossil Q, Ticwatch, Michael Kors, Huawei Watch, LG Watch, ASUS ZenWatch, Samsung Gear Live, TAG Heuer, and many more. If your watch doesn't have a barometer, the app can use your phone's barometer as well. If your smartwatch is not listed, please check if it runs on Wear OS (former Android Wear).

Overall, Altimeter for Wear OS Android is a useful and accurate app for anyone who needs to keep track of their altitude and vertical speed while on the go.
