Decibel Meter Sound : QUIETLOG

Most decibel meters are built to chase noise. QuietLog is built to hunt quiet. Measure any room in 30 seconds, log the calm places you find, and try to beat your own record. WHY QUIETLOG IS DIFFERENT - The scale runs 28 to 70 dBA, not 0 to 130. Other meters squash the quiet end into a few pixels. This one gives it the whole screen. - Lower is better. Every reading is scored against the quietest you have ever found. - Made for light sleepers, apartment hunters, remote workers, podcasters and anyone who values calm. MEASURE WITH CONFIDENCE - A weighted sound level measurement using the built in microphone - LAeq energy average, the number published acoustic guidelines actually use - Minimum and maximum level for every reading - Live validity checks for movement, a blocked microphone and wind - An honest instrument floor. When a room is quieter than the phone can hear, the app says so instead of inventing a number. - Single point calibration against any reference meter you own BUILD A RECORD BOOK - Every reading kept forever, searchable and filterable - Quiet bands from LOUD down to VOID, with FLOOR the hardest to earn - Records for all time, indoors, outdoors and this month - Milestones that show the exact gap left to the next one - Streaks that only count real readings SEE YOUR PATTERNS - A quiet calendar showing your best reading every day - Quietest per week, band distribution and best hour of the day - Places ranked by your own best reading, with a typical range to compare against - A rolling view of your last 30 days COMPARE AGAINST REAL GUIDELINES - Bedroom readings compared to the World Health Organization sleep target of 30 dBA - Typical ranges for bedrooms, offices, libraries, cafes, parks, trails, hotels and studios AI ANALYSIS - A plain language verdict on any reading, written from your own measurement - Explains what is likely making the sound and what would genuinely reduce it SHARE WHAT YOU FIND - Export a clean share card from any reading - Full backup and restore of everything you have logged PRIVACY AND QUALITY - No audio is ever recorded, saved or transmitted. There is no recording code in this app. - No ads. No analytics. No trackers. No account. No sign in. - Every reading, place and record stays on your device - Location is optional, and never leaves your phone - Built as a focused tool, not a feed. It opens fast, does one thing, and gets out of the way. HONEST LIMITS QuietLog uses the built in microphone and is not a certified sound level meter. It must not be used for occupational safety, legal, regulatory or medical purposes. Accuracy depends on your device and on calibration.
