Witness Audio

Your personal safety audio recorder. Set it and forget it background audio recording.

Witness Audio runs quietly in the background, keeping the last 12 hours of audio on your device. If something happens, you go back and save it. No fumbling to hit record. No missed moments. The proof is already there.
Everything stays on your phone. No cloud. No account. No one else can access your recordings.

Tamper-Proof Evidence
Every saved recording comes with a cryptographic evidence package: device-bound signatures, file hashes, trusted timestamps, and signed metadata. Each evidence package is designed to let a third party check that the recording hasn't been tampered with. Nothing else on the Play Store offers this.

Built for Real Life
Tap once to start. The app handles the rest.
-Voice detection waits for speech before recording, saving battery
-Safe Zones pause recording automatically when you're somewhere you feel secure
-Scheduled recording lets you automate when it runs
-Saved clips keep accurate timestamps that line up with reality

Privacy by Design
Recordings never leave your device. We don't upload, store, or access your audio. Location is used only on-device for Safe Zones and evidence metadata. No account required. Optional analytics can be turned off in Menu > Privacy.

Responsible Use
Recording laws vary by location. You are responsible for complying with the laws that apply to you and for getting any required consent. Do not use this app for secret recording where consent is required, for surveillance where prohibited, or in sensitive locations (e.g. medical settings, restrooms).
