A black box for your car.

Tamper-evident incident evidence, assembled and signed entirely on your phone.

Tessera records the road continuously, detects incidents, and seals each one into a cryptographically signed dossier — video, motion, and GPS — that never leaves your device. No account. No cloud. No subscription, ever.

Now at version 1.4 — with CarPlay support built in: recording arms automatically when you connect, and you can check status or mark an incident right from your car’s screen.

Every incident is sealed with a hardware-backed signature and a C2PA content credential — verifiable by anyone, with no trust in us required.

What you get

• Continuous loop recording with automatic storage management.
• Automatic incident detection, plus one-tap and “Hey Siri” marking.
• CarPlay: recording arms automatically when you connect, with live status and a mark button on the car’s screen.
• Hardware-backed signatures and C2PA content credentials on every dossier.
• An on-device AI narrative that only states what the signed telemetry shows.
• Court-ready export: video, telemetry, signature, and a one-page PDF report.

What you don’t get

• A server. There isn’t one — the app works in airplane mode.
• An account, a login, or any data collection. Ever.
• A subscription.

Free, with a one-time unlock

Continuous recording, the loop buffer, and manual clip saving are free. A one-time $9.99 unlock adds the Incident Engine: automatic detection, signed dossiers, the AI narrative, and verifiable export. No subscription, ever.
