Read full description

A sound level meter that uses the microphone your iPhone or iPad already has. Free to download. FREE • Live dB with a gauge, a 60-second chart, a held peak and MIN / AVG (LAeq) / MAX while you record. • Frequency weighting A, C or Z and Fast or Slow response, like a hand-held meter. • Noise dose mode: NIOSH or OSHA dose, TWA, projected 8-hour dose and time left, always on the A scale. • Recordings saved to History with notes, tags, place and search. • Noise alert at 85 dB, a table of everyday sounds and a hearing-safety guide. • PDF report in your language, CSV, image card and text summary. NEIGHBOUR AND WORKPLACE NOISE LOGS Record a session, add a note and the place, then export a PDF with date, duration, weighting, minimum, average, maximum, time above 85 dB and the level chart. It is a personal record, not legal evidence. PREMIUM Weekly, monthly, yearly or a one-time Lifetime purchase. Removes ads and adds a year of statistics, session comparison, the noise map, longer video with dB overlay, a custom alert threshold, background monitoring and extra themes. Free users can watch an optional ad to unlock a single export. HONEST ABOUT THE LIMITS A phone microphone is made for voice, differs between models and squashes very loud sound, so the loudest readings come out low. The app adds a built-in correction; calibrate against a reference meter for better numbers. It is not a certified Class 1 or Class 2 meter, a dosimeter or a hearing test. PRIVACY No account. Sound is analysed in memory and not stored; the Video tab records audio only inside videos you choose to record. The free version shows Google ads and may ask for tracking permission; location is used only to tag a recording, if you allow it.
