A documentation tool, not a calibrated sound meter. No account, no cloud — everything stays on your device. ### 1.2 — 2026-06-15 Version 1.2 adds three substantive improvements: Formal Complaint Letter Generator - The Share tab now includes a "Generate Complaint Letter" button that produces a ready-to-send formal noise complaint letter from your logged entries. The letter is structured the way housing attorneys recommend: date header, opening paragraph, a factual summary table (total events, peak and energy-averaged dB, consecutive-day streak, busiest hour), an ordinance context section when you have a jurisdiction selected, an impact statement citing WHO noise health guidelines, a detailed incident log of up to 15 entries, and formal demands. You can preview the full letter in-app, copy it to clipboard in one tap, or share it as a plain-text file via Mail, Messages, or any share extension. Pair it with the PDF evidence log for maximum effect. Expanded Noise Ordinance Database - 20 jurisdictions - The offline ordinance reference now covers 20 jurisdictions, up from 11. New additions: Houston TX (65 dBA day / 58 dBA night), Miami FL (60/55 dBA, quiet hours 11 PM), Philadelphia PA (65/55 dBA, quiet hours 9 PM), Minneapolis MN (65/55 dBA L10 limits), Nashville TN (60/50 dBA), Atlanta GA (60/50 dBA), Las Vegas NV (60/50 dBA), San Diego CA (55/50 dBA), and Phoenix AZ (65/55 dBA). Sources cited for each profile; all clearly labelled as reference only. Entry Search - The Entries tab now has a search bar. Type any word from a headline, your notes, or a dB value to filter your log instantly. Useful when you have a long history and need to find a specific event quickly. ## Apps similar to Quietmarks | App | Rating | Price | Category | | --- | --- | --- | --- | | [Auto Reload Page](https://appshunter.io/ios/app/auto-reload-page/id6785991132) | — | $0.99 | Utilities | | [Safe Message Shield](https://appshunter.io/ios/app/safe-message-shield/id6755031025) | — | $1.99 | Utilities | | [Sleep Fighters: Alarm Clock](https://appshunter.io/ios/app/sleep-fighters-alarm-clock/id6779346628) | — | Free | Utilities | | [PIN VAULT - Secure Passwords](https://appshunter.io/ios/app/pin-vault-secure-passwords/id397333272) | 4.2 (11) | Free | Utilities | | [ShopList simple](https://appshunter.io/ios/app/shoplist-simple/id6450104156) | 2.0 (1) | $2.99 | Utilities | | [SaveCrystal](https://appshunter.io/ios/app/savecrystal/id6780217908) | 5.0 (3) | Free | Utilities | ## More apps by Robert Corbin - [Daily Word Journey](https://appshunter.io/ios/app/daily-word-journey/id6761548266) - [Hush Secret Text: Encryption](https://appshunter.io/ios/app/hush-secret-text-encryption/id6761658175) - [Renew Guard](https://appshunter.io/ios/app/renew-guard/id6761755447) - [Receipt to PDF: Expense Report](https://appshunter.io/ios/app/receipt-to-pdf-expense-report/id6761782025) - [Route Your Pay](https://appshunter.io/ios/app/route-your-pay/id6761783719) - [Tip Arbiter](https://appshunter.io/ios/app/tip-arbiter/id6761786879) All apps by Robert Corbin: https://appshunter.io/developer/1890247992 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
