About
Your comma device records the road. Annex B makes those drive videos easy to use on iPhone and iPad.
Connect directly to a compatible comma device on your local network. Browse recent drives, preview road-camera footage, download full drives or individual one-minute segments, and prepare standard MP4 videos for playback or Photos.
Choose Original Quality to preserve the camera’s HEVC stream without re-encoding, or Compatibility to convert it to H.264 for easier sharing.
Designed to stay local:
• No account needed
• No analytics or cloud relay
• Read-only SSH/SFTP access to your comma device
• Pinned SSH host keys
• Private keys stored only in this device’s Keychain
• Photos add-only permission
Requirements:
• A compatible comma device on the same local network
• SSH enabled on the device
• A GitHub account configured on the comma device for SSH keys
Annex B includes four clearly labeled Sample Drives so you can explore the app before connecting hardware.
