SpeedMark

See the speed limit in real time and get warned the moment you go over. Invite people you trust to get alerts — no continuous location tracking. Private by design.

Know the limit. Stay ahead of it.

A few miles over is all it takes — a ticket, a higher premium, or worse. SpeedMark helps you catch it before it happens, protecting every drive.

Real-Time Speed Limits & Alerts SpeedMark displays the current speed limit while you drive and alerts you the moment you exceed it — the speedometer turns red, with an optional sound. You choose how early it warns you: at the limit, 10% over, or 20% over.

Guardian Alerts — Optional Invite up to 3 people you trust. They get a simple alert if you drive well over the limit — no continuous location sharing, no tracking, no stats. Safety, not surveillance.

Every Drive, Auto-Recorded SpeedMark runs in the background and records every drive automatically — GPS-verified speed, route, and timing. Replay any session on a map, or export it as a report with a speed graph. Recordings are cryptographically signed on your device, so they can be verified as unaltered.

Private by Design Your driving data stays on your phone — we never see it, and your drives are never uploaded. No account needed to track, record, or export — only Guardian Alerts use Sign in with Apple, to connect you with the people you invite. Sessions auto-delete after 24 hours unless you save them. You decide what to keep.

Need Proof? It's Already There Fighting a questionable ticket, sorting out an accident, or filing an insurance claim? Because SpeedMark already saved the drive, your record is right there — no dashcam footage to dig through, no relying on memory.
