The last 2 minutes of every tracked drive are saved. Replay on a map, or export a report if you need it.
SpeedMark shows the posted speed limit as you drive and warns you when you go over it by the amount you set, from 0 to 20%. The speedometer turns from white to orange to red, with an optional sound.
Invite people you trust to be alerted if you drive far over the limit or stop suddenly. Speed alerts show your speed, the limit, the street, and the time. No live map and no continuous location sharing. Safety, not surveillance.
Your driving sessions stay on your phone and are never uploaded. We don't keep your routes on our servers, and we never sell your data. Delete them anytime, or uninstall to remove everything. No account needed to track.
Whenever you need it, the last 2 minutes of every tracked drive stay on your phone for 24 hours. Save it, replay it on a map, or export a signed, time-stamped report as a PDF. Anyone can check it hasn't been tampered with at speedmark.app/verify.
"I had no idea how often I accidentally went over the limit until SpeedMark started alerting me. I am more aware now, and drive much calmer."
"Knowing I always have a record of my drive gives me real peace of mind. If anything happens, it's not just my word against someone else's."
"Most other driving apps wanted my location around the clock. SpeedMark keeps it all on my phone. That's exactly why I trust it."
Intelligent Speed Assistance (ISA)
Intelligent Speed Assistance reads the posted speed limit and warns you when you go over. It's required in every new car sold in the European Union. Some U.S. states are evaluating ISA laws. Highway-safety regulators call it a promising tool against speeding, which still kills more than 11,000 Americans every year.
In-car ISA only comes in new vehicles and managed fleets. The hundreds of millions of cars already on the road have none. SpeedMark puts ISA-style speed awareness on your phone — real-time limits and warnings — so the car you already drive gets it too.
1 Governors Highway Safety Association, 2026. 2 EU General Safety Regulation. 3 NYC DCAS and U.S. DOT Volpe Center, 2024. SpeedMark is an independent app that provides advisory speed-limit alerts; it is not a certified in-vehicle ISA system.
