SilentProof Support

SilentProof uses your iPhone's built-in microphone calibrated with A-weighting standards used by professional sound meters. While smartphone microphones have limitations compared to dedicated sound level meters, they provide consistently accurate relative measurements suitable for documenting noise complaints.

For the most accurate results:

• Remove any phone case during recording
• Hold the phone steady with microphone facing the noise source
• Avoid wind or air conditioning that might affect the microphone

Yes! SilentProof is designed to continue monitoring in the background even when your phone is locked or you switch to other apps. This is essential for documenting intermittent noise disturbances that may occur over several hours.

The app will continue recording audio samples and decibel measurements until you manually stop the recording or the maximum recording time is reached.

The Pro version ($6.99 one-time purchase) allows unlimited recording length, perfect for documenting extended disturbances or overnight noise issues.

Recording length is primarily limited by your phone's available storage space and battery life. The app is optimized for efficient battery usage during extended recordings.

Each SilentProof report includes:

• Precise GPS coordinates and address of the recording location
• Start and end timestamps with timezone information
• Minimum, maximum, and average decibel levels
• Visual decibel timeline chart showing noise patterns
• Comparison to relevant noise ordinances and health standards
• Time periods where noise exceeded local regulations
• Verification hash for report authenticity
• Professional formatting suitable for official complaints

Yes, but only when you start a recording session and only to document where the noise disturbance occurred. This location data is essential for official complaints as it proves the incident happened at your residence or workplace.

Location data is:

• Only captured at the moment you start recording
• Stored locally on your device
• Never transmitted to external servers
• Included in generated reports to verify incident location

All your recordings and evidence are stored locally on your iPhone using Apple's secure SwiftData framework. Nothing is transmitted to external servers by default.

Pro users can optionally enable iCloud sync, which backs up evidence to their personal Apple iCloud account using end-to-end encryption. This allows access to your evidence from other devices signed into the same Apple ID.

BorealBit never has access to your recordings or personal data.

SilentProof reports are designed to provide professional documentation that supports your noise complaints. While we cannot provide legal advice, the reports include verification features and professional formatting commonly accepted by property managers and housing authorities.

For formal legal proceedings, consult with an attorney about evidence requirements in your jurisdiction. The detailed timestamp and location data in SilentProof reports can support your case.

SilentProof Pro ($6.99 one-time purchase) includes:

• Unlimited recording length (vs 2-minute limit in free version)
• Professional PDF report generation
• iCloud sync and backup across devices
• Background recording capability
• No advertisements or interruptions
• Priority customer support

The free version allows you to test the decibel meter functionality before purchasing.

• GPS timestamping proves when and where incidents occurred
• Background recording for overnight or extended monitoring
• One-time purchase - no expensive subscriptions
