iPhone Dashcam App with Biometric Lock: Hawk by MRVL
Hawk by MRVL is a dashcam app that turns your iPhone into evidence-grade recording hardware with a biometric-locked Evidence Locker, SHA-256 integrity hashes on every clip, and one-tap export for insurance claims or court.
What Is Hawk's Biometric Lock Feature
Hawk's Evidence Locker uses biometric authentication (Face ID or Touch ID) to secure your recorded clips. The lock is fail-closed, meaning if biometric unlock fails, the evidence remains encrypted. Every clip is hashed with SHA-256 before storage, creating a tamper-evident record that courts and insurers recognise as proof the footage has not been edited. When you export a dispute, Hawk bundles the video, GPS metadata, and a SHA-256 manifest into a single ZIP file you can send directly to your insurance company or police. This combination of biometric security and cryptographic integrity makes Hawk suitable for commuters, rideshare drivers (Uber, Lyft, Bolt), and anyone who needs driving evidence without buying a separate dashcam device.
Continuous Recording and Stabilisation
Hawk records continuously while mounted on your dashboard, using cinematic optical-flow stabilisation to smooth footage from bumps and road vibration. The app runs in the background and automatically loops over old clips once storage fills up, so you do not have to manage recordings manually. GPS overlay adds speed and timestamp data to each clip, locked behind a GDPR setting so you control whether location is recorded. The free tier keeps 10 clips per month with 7-day retention; Local Pro upgrades to unlimited clips with longer retention and iCloud sync, while Rideshare Pro adds cabin camera and shift mode for drivers managing multiple trips in a single session.
Court-Ready Export and Dispute Filing
When you need to file an insurance claim or report a road incident, Hawk's one-tap dispute export generates a ZIP file containing your video, the SHA-256 integrity manifest, GPS track replay, and metadata. This bundle is designed for small-claims court, insurance adjusters, and police reports. On iOS, Hawk integrates with NDSP police-report submission so you can file directly from the app. The manifest proves no frame has been removed or modified after recording. As of 2026, Hawk's export format is accepted by most UK insurers and civil courts as supplementary evidence, though always check your insurer's specific requirements before relying on it as your sole proof.
Pricing and Subscription Tiers
Hawk's free tier lets you test the app with 10 clips per month and 7-day retention. No credit card is required. Local Pro costs £3.99 per month, £39.99 per year, or £49.99 as a one-time lifetime purchase; it includes unlimited clips, longer retention, and iCloud sync for Pro recordings. Rideshare Pro is £8.99 per month or £69.99 per year, unlocking cabin camera recording, shift mode for multi-trip sessions, and passenger-recording notices required by most gig platforms. All tiers are free to download from the App Store or Google Play.
Who Should Use Hawk
Hawk suits daily commuters who want evidence of accidents or road incidents without the cost of a hardware dashcam, new drivers building a safety record, and rideshare drivers (Uber, Lyft, Bolt) who need to protect themselves and comply with platform policies. The biometric lock ensures your footage stays private; continuous recording means you capture incidents you did not expect. Because Hawk runs on your existing iPhone or Android, setup is instant and there are no wires, power cables, or windscreen mounts to buy separately. If you are already carrying your phone, you already have your dashcam.

Frequently asked questions
Does Hawk require a subscription to start recording
No. The free tier records up to 10 clips per month with 7-day retention. You can test Hawk's core dashcam features at no cost; paid tiers unlock unlimited clips and longer storage.
Can I access my Evidence Locker recordings without biometric unlock
No. Biometric lock is fail-closed, so even you cannot view locked clips without Face ID or Touch ID. This is intentional; it prevents accidental access or tampering with evidence.
Will Hawk upload all my recordings to MRVL's servers
No. Hawk stores clips locally on your phone by default. Pro tier clips can optionally sync to your own iCloud account for backup, but MRVL does not host your footage.
Does Hawk work as a connected hardware dashcam like Viofo or Thinkware
No. Hawk is a software app that uses your iPhone or Android as the camera. It does not require external hardware, subscriptions for cloud storage, or WiFi connections. If you want a dedicated dashcam device, Hawk is not a replacement; if you want evidence-grade video on the phone you already carry, Hawk is the fastest option.
Can rideshare drivers use Hawk legally
Yes. Rideshare Pro includes a passenger-recording notice feature to comply with platform policies and local privacy law. Always check your rideshare platform's terms and your jurisdiction's recording consent rules before using cabin camera.
What happens if my phone is stolen or my screen breaks
If you are on Rideshare Pro or Local Pro, locked clips are backed up to your iCloud account and can be recovered on a new device. Free tier clips are stored locally only and cannot be recovered if the device is lost.
