MileCheck
Your mile marker.
Your nearest highway mile marker, shown to a tenth of a mile. The data is stored on your phone, so it works with no signal. All 50 states, plus kilometre markers in 10 Canadian provinces and territories. Always free.
My dad took a seasonal job driving snowplows for ODOT. Before long I realized how much of that job revolves around mile markers — radio calls, crash reports, and closures. They’re how crews track where sand, salt, and brine have been applied, and how dispatchers coordinate a response.
If you call for help on a mountain highway, how do you tell anyone exactly where you are? That’s what mile markers are for. Most drivers pass hundreds of them without a second thought. But the people who keep roads open, respond to emergencies, and help stranded motorists rely on them every day.
There was one app for this, but it only worked on iPhone. My dad uses Android. So I built him a web app that showed his nearest Oregon mile marker from GPS. My mom, my sister, and I spent hours driving highways and back roads, checking numbers, making adjustments. I still remember the first time the number changed at exactly the right moment.
My dad showed it to coworkers. They showed it to others. Feedback came from truck drivers, road crews, first responders, and everyday drivers. Nearly every feature in MileCheck exists because someone on a real road asked for it.
What started as a simple tool for my dad turned out to be useful for a lot of other people, too.
