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.
• Display barometric pressure (sensor value) or mean sea level pressure (MSLP - value used in weather forecast services or stations).
• 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" (paid feature) enabled.
• "My Area" allows you to define your frequent stay places, and the app tracks air pressure with location data.
• Export history to CSV format and Today widget (paid features).
• This app is the digital version compared with an aneroid or mercury barometer and can be adjusted to MSLP with additional features.

You can change your barometer/altimeter appearance with:
• Seven different housing colors.
• Black, white or blue disk background.
• Four different app backgrounds.
• Three different types of needles.
• Marker needle for easily monitor.
• Dark or light Today widget theme.

• App only works on devices with a barometer sensor, such as iPhone 6/6s/7/8/X/11/12/13 (including Plus models), iPad Mini 4/Air 2/Pro, or later.
• Weather icons on the dial: This only shows the air pressure trend like in an analog barometer.
• Each time your device reboots, open the app for tracking with the "Exact update interval" feature work.
• You may take the phone/tablet far away from computers, cables, and other magnetic sources to get accurate results.

Developer Response ,

Thank you for the feedback.

Mr.hernandez sir ,

Excellent app, despite poor documentation

It has ads.
It's difficult to understand some of the features...

But it does exactly what it needs to do.

Nothing fancy or distracting,

Well done.

PS. I really REALLY wish I could contact someone to clarify some features:

History Graph

The history graph records the wrong readings when the barometer is not on completely open to the front of the list of things you have open. Other then that I truly love the app.

Developer Response ,
