LärmLog: Noise Documentation

LärmLog: Noise Documentation is a compact digital noise diary designed to help tenants, families and shift workers record disturbances and build clear evidence before speaking to a landlord or lawyer. The app lets you log each incident with date, time, duration, category and free-form notes and can show live decibel readings from your phone microphone without recording or storing any audio.

Key Features

Live decibel measurement: LärmLog: Noise Documentation displays sound levels in real time and stores only dB values so no audio files are kept.

Manual entries: Add start and end times, duration, category and contextual notes when measurement isn’t practical or available.

Predefined categories: Six common categories (Music/Parties, Construction, Footsteps/Stomping, Dog Barking, TV/Radio and Other) make logging faster and more consistent.

Chronological log with filters: See incidents in order and filter by date to prepare a clear timeline of disturbances.

Notes field: Include details such as “bass through bedroom wall” or “child couldn’t sleep” to provide context for each entry.

Optional PDF export (premium): Produce a table-style PDF with date, time, duration, decibel readings, category and notes for meetings with landlords or legal advisors.

Advantages

Local-first privacy: LärmLog: Noise Documentation keeps data on your device only; there are no accounts, servers or cloud backups unless you choose to export.

Privacy-focused measurement: The app records sound levels but does not record voices or raw audio, helping to avoid legal issues related to audio recording.

Unlimited local entries and a one-time premium purchase remove ads and enable PDF export without recurring subscription fees.

Disadvantages

No cloud sync or remote backup, so if the device is lost the local log may be unrecoverable unless you exported the data beforehand.

PDF export and ad removal require the one-time premium purchase rather than being available in the free tier.

The app does not record audio, so documentation relies on decibel readings and written notes rather than playable recordings.
