Measure real-world noise levels instantly - one-time purchase, no subscription, no ads, 100% offline. DeciCheck is the no-nonsense decibel meter for anyone who needs to measure, document, and prove noise levels. Whether you're building a case against a noisy neighbor, checking workplace machinery for safety compliance, or simply curious how loud a venue is, DeciCheck gives you accurate, exportable readings from your iPhone. THREE WEIGHTING MODES - ALL FREE dBA (human-hearing weighted), dBC (low-frequency weighted), dBZ (raw unweighted). Unlike competitors who lock dBA behind a subscription, DeciCheck gives you all three from day one. LIVE HISTORY CHART Watch noise levels trend in real time with a scrolling dB chart. Min, Max, and Leq (equivalent continuous sound level) statistics update live during every session. CALIBRATION OFFSET Adjust the +/- 30 dB offset to match a professional reference meter, compensating for your iPhone model's microphone sensitivity. SESSION RECORDING Start a session, give it a name and note (e.g. "Upstairs neighbor at 11 PM"), then save it. Browse your full history in the Sessions tab. CSV AND PDF FORENSIC EXPORT Export any session as a timestamped CSV or a formatted PDF report with stats and chart. Share directly with landlords, property managers, HOA boards, or HR - the report is designed for real disputes. SOUND LEVEL REFERENCE TABLE A built-in guide from 10 dB (rustling leaves) to 140 dB (explosion) helps you understand what your readings actually mean. WHY DECICHECK? - $2.99 one-time purchase, no recurring fees, ever - All audio processed on-device; never recorded, stored, or transmitted - No ads, no analytics, no third-party SDKs - Works in airplane mode - Supports iPhone and iPad (iOS 17+) Disclaimer: DeciCheck provides reference measurements and is not a certified or professional sound level meter (IEC 61672). For legal or occupational certification, use a calibrated instrument.
