Messwerk

Messwerk — the measurement toolbox in your pocket. Six precise tools in one app — led by a full dB noise meter. No subscriptions, no ads, no clutter. SOUND LEVEL / NOISE METER Measure ambient noise and loudness in decibels dB(A) with professional A-weighting, min/max and average (Leq). Pause runs, save them with names, browse your history and export everything as CSV. SPIRIT LEVEL Precise 2D bubble level with degree readout and haptic feedback when level. COMPASS A clean compass rose showing magnetic heading. BAROMETER Air pressure, altitude changes with a reference point, and absolute altitude above sea level. SPEEDOMETER GPS speed with maximum, average and trip distance. STOPWATCH & TIMER A drift-free stopwatch with lap times and a countdown timer up to 24 hours. Every tool is honest about its accuracy and limits. All measurements stay on your device — no data collection, no accounts, no trackers.
