About Quietmarks
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.
