About this app

The pressure or barometer sensor in your device is continually monitored and when the detection level is crossed, the counter is increased by one.

Can be used to count each time a pressure changing event occurs such as elevation changes, a room door closing or a gust of wind.

• Select between Pascals, bar, mbar, psi, Torr, atmospheres or inches of mercury for the displayed pressure unit.

• Detect on rising or falling past the detection level.

• Reduce double counts with optional no-count wait after detection.

• Graph to show pressure values versus time.

• Counts indicated on graph and with optional 'click' sound.


Pressure sensors will vary in sampling speed, resolution and accuracy from one device to the next. For indication only.
