Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Measure sound levels with a clean live dB meter, A/C/Z weighting, Fast/Slow response, Leq and C Peak. Save sessions and export clear reports or CSV. Measure sound levels clearly with MnmlDB, a clean and focused decibel meter for iPhone. View real-time dB levels, follow changes over time, and inspect the measurements that matter without a cluttered interface. Whether you're checking the noise in a room, comparing sound levels, monitoring music or equipment, or simply curious about how loud your surroundings are, MnmlDB gives you an easy way to measure and document sound. LIVE SOUND MEASUREMENT • Real-time decibel level • Live sound level graph • Minimum and maximum levels • Leq average sound level • C Peak measurement • Measurement duration A, C & Z FREQUENCY WEIGHTING Choose between A, C and Z weighting depending on the type of sound measurement you need. FAST & SLOW TIME WEIGHTING Switch between Fast and Slow response modes to control how quickly the displayed sound level reacts to changes. CALIBRATION Adjust the calibration offset to better match a reference sound level meter or account for differences between devices. SAVE YOUR MEASUREMENTS Keep measurement sessions for later and review their level history, minimum, maximum, average and peak values. EXPORT RESULTS Create a clear measurement report or export session data as CSV when you need to keep, share or analyze your results elsewhere. PRIVATE BY DESIGN Microphone audio is analyzed on your device for sound-level measurement and is not recorded. BUILT TO STAY OUT OF THE WAY MnmlDB focuses on the measurement itself: clear readings, useful controls and a minimal interface without unnecessary distractions. Please note that measurements made using an iPhone microphone can vary between devices and environments. MnmlDB is intended as a practical sound-level measurement tool and should not replace a certified sound level meter where formally calibrated measurements are required.
