Volume Zone vs MeterWorks Sound Meter

Volume Zone automatically adjusts your media volume based on where you are. Set it up once, and your phone takes care of itself. How it works Create a zone for any location — home, work, the gym, a library. Assign a volume level and notification tone to each zone. When you arrive, Volume Zone silently applies your settings. When you leave, it restores your defaults. Why you'll love it No more blasting music when you walk into the office. No more missing calls because you forgot to turn the volume back up at home. Volume Zone handles all of it in the background, without you lifting a finger. Features Set a custom media volume for any location Choose a notification sound per zone Visual map picker with address search, just tap to place a pin Adjustable geofence radius (50–500m) to suit each location Instant status on the home screen showing your active zone Runs silently in the background using iOS location services Unlock unlimited zones with a one-time Pro upgrade Free tier includes Home and Work zones — the two locations most people need most. Pro unlock Add as many zones as you like with a single one-time purchase. No subscription.

When noise becomes a problem, the loudest number doesn't win — the complete log does. MeterWorks Sound Meter is a sound level meter and noise log in one: measure, document incidents, export the log PDF. No ads, no subscription, no account. NOISE LOG — THE HEART OF IT • Every incident with start, duration, type, and measured level — turn any recording into a diary entry with one tap • Tag events with one tap: bass/music, footsteps, dog, drilling, traffic … • Pro: automatic events — when the level crosses your threshold, the entry creates itself with start, duration, Leq, and max level • Export a log PDF in the tabular form landlords and mediators expect: date, time, duration, type, measured levels, notes — with a methodology footer • Fair by design: the app stores NO audio — only level values. No secret recordings, no legal gray zone MEASURE • Live readout with a big dB(A) value, Fast/Slow weighting, smooth real-time graph • Leq, LAFmax, LAFmin — the numbers that belong in real reports • Pro: dB(C)/dB(Z) weighting and L10/L50/L90/L95 percentiles (background vs. events) • Offset calibration against a reference meter — wide ±25 dB range, because devices drift YOUR DATA IS YOURS • Free: PNG export of any measurement • Pro: CSV of the full per-second series (LAeq/LAFmax/LAFmin) — spreadsheet-ready, shared in seconds • Pro: multi-page PDF report with statistics, level history, and the event table FREE VS. PRO — NO SURPRISES Free is a real instrument: unlimited live measurement, three recordings of 10 seconds each, 3 manual diary entries per day, PNG export. Pro is a single one-time purchase: recordings without time or count limits, auto events, CSV, log PDF, percentiles, dB(C)/(Z) — all future Pro features included. No subscription, ever. WHAT THIS APP CANNOT DO — HONESTLY iPhone microphones measure reliably from roughly 30 to 100 dB(A), within ±2–3 dB after calibration. Certified, court-grade measurements are beyond any smartphone — apps promising that are bluffing. The log serves documentation; the in-app page "Limits of this measurement" explains exactly what works. TYPICAL USES Document neighbor noise · back up a complaint with timestamped data · level a home theater or rehearsal room · compare machine and fan noise NO SUBSCRIPTION. NO ADS. NO TRACKERS. All measurement data stays on your device. MeterWorks is a family of honest measurement apps: Vibrometer for vibration, Teslameter for magnetic fields — just as honest, just as subscription-free.
