Quietmark is a local-first noise documentation tool for apartment, neighborhood, construction, and late-night disturbance logs. Capture a short microphone meter sample, add notes and optional photos, review recurring patterns, and export clean PDF, CSV, or plain-text documentation packets. QUIETMARK IS BUILT FOR ONE THING People who need a dated, organized record of repeated noise events. Sound-meter apps show a number. Notes apps store text. Quietmark combines short approximate dB readings, written context, optional photo attachments, pattern summaries, and shareable exports in one private workflow. CAPTURE THE EVENT - Tap the big button. Quietmark opens the microphone for 3 / 5 / 10 / 30 seconds (your choice in Settings). - It samples the audio meters at 10 Hz to estimate peak and average loudness. - Quietmark is not a calibrated sound level meter. Readings are approximate and intended for personal documentation only. - The microphone is used only for short captures you start yourself. Temporary audio is deleted after metering and nothing is uploaded. LOG THE DETAILS - A one-line headline + multi-line notes. - Optional structured fields for source, room affected, duration, impact, and witnesses. - Optional photo attachment from your photo library. - Day-grouped reverse-chronological list with "Today" / "Yesterday" / weekday / date headers. - Search your log by headline, notes, or dB value. EXPORT CLEAN PACKETS - PDF log: Letter-size packet with dates, approximate dB summaries, notes, source context, and optional photo thumbnails. - CSV spreadsheet: Opens in Numbers, Excel, or any spreadsheet app for sorting and filtering. - Plain-text summary letter: Generate a concise documentation summary from selected entries, then copy or share it through the iOS share sheet. - Evidence-readiness checklist: A 0-100 completeness score that highlights missing basics such as contact block, repeated dates, notes, source context, and calibration disclosure. OFFLINE REFERENCE LIBRARY - 20 US and international jurisdictions: NYC, LA, Chicago, Boston, Seattle, San Francisco, Portland, Denver, Houston, Miami, Philadelphia, Minneapolis, Nashville, Atlanta, Las Vegas, San Diego, Phoenix, WHO guidelines, EPA Levels Document, and a typical US residential composite. - Each profile shows daytime/nighttime reference values, quiet hours, and citation text. - The Sources screen includes public references such as WHO environmental noise guidelines, the U.S. EPA Levels Document, CDC/NIOSH measurement guidance, and selected public ordinance pages. - Reference data may become outdated. Always verify current local rules before relying on a specific threshold. PRIVACY-FIRST - Everything stays on this device. No cloud sync. No accounts. No analytics. - The microphone is only used during a deliberate capture; there is no background listening. - The photo library is read only when you choose to attach an image - and again, that image stays local. ABOUT THE DECIBEL NUMBERS Apple does not expose a calibrated sound level meter through standard app APIs. Quietmark uses AVAudioRecorder's standard metering APIs and converts them to an approximate loudness reading. The number is useful for personal documentation and relative comparisons; it is not professional measurement data. Settings includes a full calibration note in plain English. WHO IT'S FOR - Renters and homeowners tracking recurring noise events. - Apartment and HOA residents organizing dates, notes, and attachments before a conversation or written complaint. - Anyone who wants a private, dated noise log with polished export tools. Quietmark is not a medical device, legal service, or professional sound level meter. ## Version history (last 5 releases) ### 2.1 — 2026-06-30 Version 2.1 adds a pro documentation pass: **Evidence-readiness checklist** - The Share tab now scores whether a packet includes enough basic context before export: repeated dates, written notes, source details, property/contact fields, selected reference profile, and calibration disclosure. **Sources & Citations** - Settings now includes a Sources screen with public reference links for environmental noise context, measurement caveats, and selected local ordinance pages. **Cleaner exports and copy** - PDF and plain-text exports now include clearer calibration language, source citations, and safer reference-only wording. ### 2.0 — 2026-06-21 Quietmarks 2.0 — a pro upgrade that turns samples into a credible case file, still 100% offline. • Structured incident log: category, source, room, impact, witnesses, and whether police were called. • Recurrence engine: a weekday × hour heatmap and a 0–100 credibility score that turns scattered events into "noise typically Fri–Sat, 11 PM–1 AM." • Quiet-hours flagging (with correct past-midnight math) and disturbance-minute analytics. • A calibration offset so you can match a reference and improve your readings — always shown honestly as an approximation. • Upgraded evidence-package PDF with a Pattern Analysis & Methodology page, plus a complaint-letter generator that includes the recurrence summary. 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. ### 1.1 — 2026-06-14 Version 1.1 adds four substantive improvements: CSV Export — Share your noise log as a spreadsheet-compatible CSV from the Share tab. Every column a lawyer or property manager needs: peak dB, avg dB, duration, notes, photo flag, and timestamp in ISO 8601. Opens in Numbers, Excel, or Google Sheets. Statistics View — Tap the chart icon on the Entries tab for a real analytics panel: total events, events per active day, longest consecutive streak, overall peak and energy-averaged dB, level distribution (how many events hit 70 dB and 85 dB), an hour-of-day sparkline, and a day-of-week breakdown. Noise Ordinance Reference — An offline database of noise ordinance limits for 11 jurisdictions (NYC, Los Angeles, Chicago, Boston, Seattle, San Francisco, Portland, Denver, plus WHO guidelines and the US EPA reference). Choose your city in Settings; each entry's detail view then shows a badge — comfortably below, near, or above the applicable limit for that time of day. Sources cited throughout; clearly labelled as reference only. Live Ordinance Context on Entry Details — With a jurisdiction selected, every entry detail view shows the applicable daytime or quiet-hours limit for that timestamp and whether the peak reading exceeded it. ### 1.0 — 2026-06-10 No release notes. ## More apps by Robert Corbin - [Daily Word Journey](https://appshunter.io/ios/app/daily-word-journey/id6761548266) - [Hush Secret Text](https://appshunter.io/ios/app/hush-secret-text/id6761658175) - [Renew Guard](https://appshunter.io/ios/app/renew-guard/id6761755447) - [Receipt to PDF](https://appshunter.io/ios/app/receipt-to-pdf/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/).
