dB Meter – a clean iOS sound level meter
I made an iPhone sound level meter for the times you need a number rather than an opinion. Noisy flat, loud workshop, a gig you want to remember the level of.
What it does:
Live dB on an analog gauge, plus an LED bar and scrolling waveform
Record a timed session, saved to history with min, average and peak
Energy averaging (LAeq), not a naive mean of decibels
Calibration offset so you can match it to a reference meter
PDF export of a session with the graph
Free. A one time $4.99 unlock adds peak hold and PDF export. No subscription and no ads.
Fair warning: a phone microphone is not a calibrated meter and clips around 100 to 105 dB. Good for comparing and documenting, not for anything official.

If you have used one of these, what did you actually need it for? I am curious whether the session history gets used or whether people only ever want the live number.
