What Noise Log does

One-tap incident log

Live sound-level meter (approximate, the phone microphone is not calibrated), automatic timestamp and a duration timer, with a clear recording indicator.

Noise types and impact

Music and bass, stomping, shouting and parties, dog barking, construction, machinery and street noise, plus impact tags like could not sleep and child woken.

Quiet-hours flagging

Incidents during your quiet hours (default 22:00 to 07:00) are marked as night-time disturbances.

Calendar heatmap

See every incident on a calendar, plus a weekday-by-hour heatmap and a per-week trend.

PDF incident report

Incident table with approximate sound levels and durations, summary stats, charts and an integrity page with device details and a fingerprint per entry.

Complaint letter templates

Prefilled, editable letters for your landlord, council or building manager, tailored to your country. Review before sending.

How it works

  1. Log the incident. When the noise starts, tap Log incident now to capture the time, an estimated level and the duration. Missed one? Add a past incident by hand.
  2. Tag the impact. Pick the category and how it affected you, add notes and where it came from.
  3. See the pattern. The calendar and analytics show how often and when it happens.
  4. Share your record. Generate a PDF report, a complaint letter or a CSV, and send it to whoever can help.

Record noise, not conversations

Recording laws differ between countries. Audio clips are optional and are for noise only. In some places, such as Germany (StGB section 201), recording private speech is illegal. Recording only ever runs in the foreground with a visible indicator. There is no background or hidden recording, and everything stays on your device.

Questions

Do I need a council or subscription service?

No. Many noise apps only work in the areas that pay for them. Noise Log is yours: keep your own record and decide who to send it to.

Can I record audio of the noise?

Audio clips are optional and are for noise only. Recording laws differ between countries, and recording private conversations is restricted or illegal in some places. Check the rules where you live. Noise Log leads with the written log and approximate levels and keeps audio optional.

Where is my data stored?

On your device. There is no account, no backend and no analytics. Data only leaves your device when you share an export yourself.

Is the sound level an official measurement?

No. A phone microphone is not a calibrated sound-level meter, so the figure is an approximate estimate that adds context to your written log. It is not a professional measurement.
