Advance barometer app with pressure tracking, custom notification when pressure change.

Barometer Plus app measures air pressure and altitude using your device's built-in barometric pressure sensor.
Because air pressure changes usually indicate a weather change, you can use this app to monitor and predict short-term weather variations.
People suffering from migraine, headaches, or joint pain can monitor how barometric pressure impacts their mood.
Fishermen can monitor the atmospheric pressure for right-time fishing.

• The app contains a barometer and altimeter with a personalization graphic in classic analog style. It also displays the current temperature and humidity.

• Units support for pressure: mb, inHg, kPa, atm, Torr, psi, hPa, mmHg. Units for altitude: meter, feet.
• Calibrate the barometer using altitude/location from the GPS. Calibrate the altimeter using the nearest airport information/METAR, or manually enter the QNH of the nearest airport. Offset sensor output value.
• Measure the height (building/mountain/hiked/climbed) using the "Relative Altitude" feature (can be enabled in the app's Settings).
• Notification about pressure change. "Notification custom rule" for you to define how and when the app sends notifications.
Notify when air pressure changes indicate that extreme or worse weather may occur.
• "Pressure Tracking" and "History Graph" require "Background App Refresh" or "Always Location Service" with "Exact update interval" enabled.
• "My Area" allows you to define your frequent stay places, and the app tracks air pressure with location data.

Pain advanced warning

I too find that my chronic joint pain seems to be mirrored by the Barometric Pressure and I use the 14 day chart to get a hint as to when I need to wait it out on meds and in bed. Just not worth bothering doing anything important!? The heads up let’s me prepare accordingly.

The entire program is terrific.

Only wish there was an explanation on how all the data is collected like Altitude...

Information and Weather

Understanding weather for me, call me average person, is elusive. Barometric pressure is a venerable and valuable tool in this pursuit. Barometer Plus is a step in the right direction. There are deficiencies and problems in the app, but none fatal. Hopefully it will be improved or there is a better app, I’m open to both.
