About this app
Sound Pressure Level Meter. This app uses the microphone to detect sound and convert it into an SPL value. FOR INDICATION ONLY. Results depend on your device and its hardware. The range between the noise floor and saturation may be only 20 dB on the worst devices, but could exceed 100 dB on the best devices.
Features of this SPL meter include:
Analogue Dial with Max and Min indicators.
Weighting – A, C or None . (A weighting filters the high and low frequencies according to how the ear perceives sound loudness). Results are in dB, dBA or dBC depending on weighting.
Averaging of SPL, Clear and Pause buttons.
Octaves and third octaves - Frequency spectrum of the sound.
Graph – Shows the time depedence of the sound.
Autoscale or manual (pinch & pan) Y-Axis.
Relative button – if looking for differences, tapping REL will remove the current averaged value from the reading.
Calibrate option – If you have a calibrated SPL meter or known loudness source, you can use this option to calibrate the meter. (However its still for Indication Only).
More technical details can be found on the website.

Simple and dead accurate after calibration. I use it to quick-check our speech test setup. This app actually was accurate enough to notice a slow drift in the calibrated sound level of a few dB over a period of weeks. It tuned out to be a faulty transmitter device in the setup.

Has A and C weighting and a smooth refresh rate which makes it very useful for SPL calibrations with home studio setup. Has a handful of useful features without the fuss of other apps that pretend to charge a subscription for no reason. Thanks to the devs.

Not up to date. "Built for an older version of Android". Numbers totally wrong out of the gate, says 90dB from A/C noise and normal 'inside voice' conversation when other apps more accurately start at around 62dB before calibration. Interface is also kind of old-looking and sluggish.
