Bar-o-Meter reads the pressure from the barometer sensor and it uses it to calculate your altitude. It also gives you weather forecast and it shows the pressure in different measure units.
On old devices not equipped with a barometric sensor, the app uses accurate internet services to also display pressure and altitude.


▪ Find your altitude from the pressure measured from your device, thank's to the Barometric Formula, and from your location
▪ Widget, to always keep an eye on pressure
▪ Pressure and altitude charts
▪ Relative Altitude, to get how up and down did you hiked, based on the pressure measure of your device
▪ Multiple measure units
▪ Amazing animations and Flat Design graphic!

… and much more!

Absolute Pressure

How do I get the app to display actual pressure in inches of mercury instead of absolute pressure? Thanks.

Needs Apple Watch support

Needs to run in background.

Needs to show the last 24 hours of pressure data.

Add sun and rain icons to barometer to quickly indicate predicted weather.

Needs ability to zoom out on the graph to see more hours at once without side scrolling.

It would be cool if you could rotate the iPhone sideways so the graphs would be bigger and show more data at once.

Needs Apple Watch support
