Measurements now keep themselves. Stop the meter and the reading is saved — average, maximum, minimum, duration and the full level trace. There's no Save button to forget: it's already in History, behind the clock in the corner. Export any measurement as a CSV to send to a landlord, a contractor or a colleague, with the calibration and weighting it was taken under included, so the numbers mean something to whoever receives them. Four numbers, not one. The level right now, large, with the running average (Leq), maximum and minimum beneath it, and how long you've been measuring. LCpeak, for alarms and impulses. An average describes a room. It doesn't describe a fire alarm or a slammed door. LCpeak is the true peak, measured the way sound level meters measure impulses — and if the input clips, Decibels says so instead of quietly reporting a number that's really a floor. A clearer graph. Ten seconds of history on a fixed timeline, drawn as a smooth curve that never invents a peak the microphone didn't hear. It no longer flattens out above 100 dB. Fixed: the needle sat off its pivot on larger iPhones, and starting the meter without microphone access could close the app — it now explains what's wrong. If Decibels earns its keep, there's a way to buy me a coffee in Settings.
