LärmLog: Noise Documentation

Document neighbor noise & measure decibels. PDF for landlord. Offline.

Your neighbor blasts music until 2 AM. You complain to the landlord. Response: "Prove it." Without consistent noise documentation, tenant disputes fail—rent reduction claims collapse due to lack of evidence.

LärmLog is a digital noise diary for tenants. You document every disturbance with date, time, duration, category, and notes—structured, chronological, without secret recordings (compliant with wiretapping laws).

WHAT LÄRMLOG DOES (FREE):
✓ Live noise measurement – captures decibels in real-time via your phone's microphone. No audio is recorded or stored. Only dB values go into your log.
✓ Manual entry – when measuring isn't practical: start time, end time, category, notes—done.
✓ 6 noise categories – covers the most common sources: Music / Parties, Construction, Footsteps / Stomping, Dog Barking, TV / Radio, Other.
✓ Chronological entry list – all incidents at a glance, filterable by date.
✓ Notes field – free-form text for context ("bass through bedroom wall", "child can't sleep").
✓ Unlimited entries – no artificial limits or paywalls.
✓ 24 EU languages – the app runs in every official EU language.

100% OFFLINE & PRIVATE:
All data stays on your device. No cloud, no server, no login, no account. We measure only sound levels (decibel values)—we don't record audio, store voice, or transmit anything online. LärmLog operates outside the scope of wiretapping laws.

FOR WHOM:
Tenants with loud neighbors. Families whose children lose sleep to construction or barking. Shift workers denied rest hours. Anyone who needs written proof of noise disturbance before speaking to landlord, property manager, or lawyer.

PREMIUM (one-time lifetime purchase):
✓ PDF export – your complete noise log as a court-ready document. Table with date, time, duration, category, decibel reading, and notes—can serve as evidence and strengthen your case with landlord and attorney.
✓ Ad-free – all ads removed.

No subscription. No hidden purchases. Pay once, use forever.

At your next landlord meeting, you'll have the answer to every question—date, time, duration, sound level—documented in writing before it's asked.
