A fast, private decibel meter for everyday noise checks
HowLoud turns your phone's microphone into a live decibel meter for everyday noise checks. It shows real-time A-weighted sound levels and tracks minimum, maximum, average and Leq values as you measure.
Save measurement sessions on your device, add notes for context, and tag readings with location. Export a clean A4 PDF report with a chart, stats and map to document and share what you found.
It's privacy-focused with no account, cloud sync or tracking. Useful for checking neighbors, appliances, traffic, events or renovations. Note that it is not a certified Class 1 or Class 2 sound level meter. It runs on iOS and Android and pairs with the browser sound meter on PickHeadphones.
