Barometer HD shows you the current barometric pressure in different units, including inHg, mmHg, hPa, atm, millibars. It also shows your altitude at STP.
This app only runs on devices with the barometric sensor, such as the Motorola Xoom and Galaxy Nexus.
Planned upcoming features include:
- Barometer Widget for the Android Desktop.
- More calibration options.
- Triggerable sound effects on major pressure changes (storm warning mode).
There are currently some issues with phone-sized screens being too small to read all of the pressure values.
