Description
mu Barometer measures real-time air pressure using your phone’s built-in barometer sensor. Track atmospheric pressure changes, monitor altitude, and analyze pressure trends with precision. Ideal for weather tracking, fishing, weather monitoring, storm awareness, outdoor adventures, and anyone who needs accurate offline pressure data. The goal of μBarometer is to be useful, small and elegant. Features: - Pressure units: mBar, mmHg, inHg, atm - Altitude units: meters, feet - Pressure Graph - Altitude Indicator - App widget with three themes - Pressure value in the status bar
The pressure graph shows the change in pressure in 48 hours. To collect data μBarometer runs a small service which saves the pressure value every hour.
The altitude value are based on the current pressure value. For quick switching between pressure/altitude indicators just tap on the indicator icon. You can measure the relative altitude. Just tap on the altitude indicator and it will show the relative altitude from the current point.

Comments on mu Barometer: Air Pressure for Android
★★★★★
Fun for weather nerds: Works well-used my home's altitude I found with a separate GPS app, plus calibrated phone error offset pressure correction (for go to: Settings>Advanced settings>Pressure calibration and enter the amount that needs to be added to the phone sensor to match local weather stations. Ever since it tracks within .02 inHg of the stations. . We just had a smallish thunderstorm go through, and the graph shows it just bottomed at 29.82 and is starting to go back up. Nerd out.
★★★★★
Nice app, with Many options, and accurate to my home's barometer. Easy to use. A nice feature that's often not in similar apps, is a "marker needle" that gives the option to mark a current reading and to go back at a later time to see what pressure change has occurred...has the pressure increased (nicer weather) or, decreased (possible rain). This free app also provides many customizable options, from weather icons (rain, cloudy, sunny), to overall appearance (provided by the app, or the user).
★★★★★
Best barometer app I've found. Lots of configuration options on free version and ads are not too intrusive. Widget is great! Plan to use it for air travel and managing sinus pressure issues.
★★☆☆☆
Not much of an app. In weather, it ALWAYS sat Improving there is a low pressure off coast coming this way!
★★☆☆☆
Edit: I said RAM, not cache or app data. Around 100 MB RAM (when not in use for days and app closed from overview screen; no widget placed!) occupied by processes?? Too much for just the logging of a sensor value! Also, suspicious! Android 9.
★★☆☆☆
I really enjoy the app, although the time on the X axis is approximately 3 hours behind. Am I missing something like perhaps a time zone setting in the settings?
