## What is DeciCheck?

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.
