This app is primarily used to measure atmospheric pressure. It could also collect weather information such as temperature, humidity, wind speed, wind direction, precipitation and cloudiness from adjacent weather stations. This app contains the following features:

1) Plot the measured data in real time.

2) Measurement duration and measurement frequency are customizable.

3) Multiple units supported: kPa, hPa, mbar, mmHg, Torr, at, kgf/cm^2, atm, inHg, psi.

4) Users could set alert value to some level (Ex. 800 hPa). When the measured pressure is lower than the alert value, it will alert users.

5) The location information of the measurement points could also be obtained, and all the measurement results could be shown in map.

6) All measured data could be exported as a csv format file for post process.

7) In addition, users could also add photos, videos and voice notes to the measured data, and the photos, videos and voice notes could be downloaded via iTunes.

Accuracy STINKS!!

I had purchased this app because it is one of the few apps that records barometric pressures and allows me to track them over time. I have migraines that are very sensitive to changes in barometric pressure. I prefer to track in inches Hg but every reading I've gotten has been between 27.3 & 27.9. Readings that low would indicate I might be in the midst of a tropical storm or hurricane not the beautiful clear skies we've been experiencing.
