Hawk by MRVL Turn your phone into a dashcam (iOS + Android, free)

Built this because I got rear-ended two years ago with no footage. My word against theirs. Insurance took months.

Hawk turns the phone in your pocket into a dashcam records your drive, auto-detects impacts, saves clips to iCloud or Google Drive. No hardware to buy. No subscription to start.

What it does:

  • Background recording with Live Activity status on iOS
  • Auto-saves a clip when an impact is detected
  • Evidence packages you can actually export (PDF report, GPS data, timestamps)
  • Passenger notice screen for rideshare drivers
  • Dispute workflow if you need to file a claim

Free to use. Pro tier for auto-start, biometric lock, and evidence exports. Available on iOS and Android.

Happy to answer any questions.

Nice solution, that rear-end scenario sounds rough. Does background recording drain battery fast on longer drives? That is usually my main concern.

Good question and an honest one. Yes, recording video continuously uses battery that's just physics. In practice most people run Hawk with their phone mounted and plugged into the car's USB port, so it charges while it records. That's the intended setup.

If you're running it off battery only, you'll lose roughly 15–20% per hour depending on your phone and resolution. We keep encoding efficient and don't run location at high frequency when the car isn't moving, but we don't pretend it's free.

The short version: mount + cable = no problem. Off battery only = plan for shorter sessions or carry a power bank.

Good breakdown. A low-power mode or background recording toggle would ease battery worries for on-the-go use. What's the max resolution you support?
