DecibelKit vs Visual Timer

DecibelKit turns your iPhone into a precision sound-level meter — built for the moments when "that seems loud" isn't good enough. A true analog dB dial sweeps with the room in real time, backed by a clean digital readout of current, minimum, maximum, and average levels. Tap into the detail the way a pro field meter would: MEASURE LIKE AN INSTRUMENT • Live analog SPL dial with peak-hold and a decaying needle • A and C frequency weighting (dBA / dBC) • Fast and Slow time response, just like a hardware meter • Min / max / average and peak capture for every reading UNDERSTAND YOUR EXPOSURE • Built-in NIOSH noise-dose dosimeter tracks your daily sound exposure • See at a glance when a space crosses into hearing-risk territory KEEP A RECORD (Pro) • Save measurement sessions with full dB-over-time history charts • Review any past session in detail • Export any session to CSV for analysis, reports, or compliance records DIAL IT IN • Calibrate readings against a reference meter for greater accuracy PRIVACY FIRST Audio is analyzed live, on-device, to compute sound levels. It is never recorded, saved, or sent anywhere. DECIBELKIT PRO — ONE-TIME UNLOCK Recording history, the exposure dosimeter, calibration, and CSV export unlock with DecibelKit Pro: a single one-time purchase, yours forever. No subscription. A quick note on accuracy: iPhone microphones are designed for voice, not laboratory-grade acoustic measurement. DecibelKit is excellent for relative readings, monitoring, and awareness, and calibration brings it closer to a reference — but it is not a substitute for a certified Type 1/Type 2 sound-level meter for regulatory or safety-critical use.
