Sound Level Meter

See how loud it is around you. A big dial shows the level, live, in A-weighted decibels, the way real sound level meters read, with a few words under the number that say what that level is like: a whisper, a quiet room, a normal conversation, heavy traffic. No ads, no accounts, and nothing watching what you do.

Tap Record to capture a clip while you measure. Recordings are saved on your device, where you can play them back, see the waveform, and find the loudest moments. One limit up front: phone microphones aren't calibrated, so the meter gives you a relative reading, not a certified SPL measurement. If you have a real meter, an offset in Settings lines the two up.

NEW IN 1.2

• A-weighted readings (dBA), with a Flat option for the unweighted number
• A 60-second graph of the level, with the 85 dB hearing-risk line across it
• A spectrum view: ten octave bands, 31 Hz to 16 kHz, with peak-hold lines
• Plain-words captions under the number
• A Log tab: save a reading with a note, or take a timed 1-minute measurement; share as text or CSV
• Colour zones and a peak tick on the dial
• A calibration offset and keep-screen-on in Settings
• Meter, Log and Recordings as tabs, and a back button that returns to the previous screen
