You're only notified when your driver is far over the limit — 20% or more — or stops suddenly. No noise, no nagging over a mile or two.
Every alert shows the road, time, and speed. Speeding alerts add the limit, so you know what happened. Safety, not surveillance.
No subscription, no in-app purchase. Anyone can be one: a parent, a partner, an adult child watching over an aging parent. Download, connect, done.
Only the driver can invite a guardian, with a 6-digit code. Nobody can add themselves or look in on someone uninvited.
A driver can add or remove guardians at any time, with up to 3 at once.
Routes, destinations, or live location. You see only the alerts they trigger.
Set it and forget it
Alerts arrive as push notifications, whether the app is open, in your pocket, or fully shut. Nothing to launch, nothing to keep running.
Someone you trust sends you a 6-digit code by text or email.
No subscription needed to receive alerts. Sign in and you're set up in under a minute.
It links you to your driver. That's the entire setup — nothing else to configure.
From then on, alerts arrive on their own when it matters. Each one stays saved for a week so you can look back.
"My son just started driving. I get a heads-up if he's really speeding — no live map, no tracking his every move. It's the only thing he actually agreed to."
"My dad's 78 and still loves to drive. I didn't want to take that from him — I just wanted to know if something looked off. This is exactly that, and nothing more."
"Every other app wanted to track location around the clock. SpeedMark just tells me if there's a real problem. That's why I trust it on my phone."
