BaroGuard: Pressure trends, altitude and climb rate on Wear OS

I built BaroGuard because the barometer inside many Wear OS watches is capable of much more than most watch apps expose. BaroGuard gives you live atmospheric pressure, local pressure trends, approximate pressure-derived altitude, and foreground-only climb/descent measurements directly from the watch. I also added local history, calibration, CSV export, pressure-change alerts, a Tile, and watch-face complications. A big design goal was keeping it genuinely watch-native. There’s no phone companion, account, location access, cloud backend, ads, or analytics. The measurement features are intended as approximate references rather than certified weather, aviation, or safety instruments. I’d love feedback from Wear OS users: what other useful things would you want to do with the barometer already on your wrist?
