Noisy neighbors are hard to challenge without a clear record. SilentProof helps renters document each incident with time, duration, reference dB levels, on-device audio, and optional notes and location context—then export a PDF for a landlord, property manager, HOA, or local complaint process. Audio starts automatically with each recording; location requires your permission. It is not just a sound meter. It is a calm documentation workflow for repeated noise issues. HOW IT WORKS 1. CAPTURE THE INCIDENT Open SilentProof when the noise starts and begin an incident record in seconds. 2. ADD THE CONTEXT Keep the details people ask for: - Reference decibel readings - Time and duration - Location context - On-device audio recording - Notes about what happened 3. EXPORT THE RECORD Create a PDF that is easier to send to: - Landlords - Property managers - Building staff - HOAs - Local complaint workflows BUILT FOR RENTERS WITH RECURRING NOISE Track issues such as: - Upstairs neighbors - Loud neighbors, bass, or late-night parties - Barking dogs - Early-morning construction - Repeated disturbances that need a pattern, not a guess WHY SILENTPROOF + Built for complaint records, not one-off readings Turn repeated incidents into a timeline you can review and share. + Privacy-first Your evidence stays on your device by default until you choose to export it. Device backup settings may also back up these files. + Quick to start Open the app and start a record quickly when noise starts suddenly. FREE AND PRO FREE: - Real-time decibel meter - Evidence capture and history - 1 PDF export PRO: - Unlimited PDF exports - Full reporting workflow - One-time purchase, no subscription IMPORTANT SilentProof is a documentation tool for recurring noise issues. It is not legal advice and it is not a certified sound level meter. Audio recording laws vary by location. Check and follow local consent requirements before recording.
