TrailTimer: UTV Trails & Laps

No account, no sign-up, no ads. Trade a code and your crew is timed together. Drive your loop once and race it in minutes, on your own land, with live gauges on screen.

Time race days on your own land, with your own crew, in the woods behind the house. Drive your loop once, slowly, and TrailTimer places the checkpoints for you. Tap START and race it the same afternoon. Every run is logged, and the leaderboard updates before your helmet is off.

No account. No sign-up. No email, no password, no ads. Trade a short code with your buddies and your whole crew is on the same clock, on the same leaderboard.

NEW WITH APPLE INTELLIGENCE AND iOS 27 Finish a run and your debrief is waiting: what happened on each leg and one thing to try next time. It's free, and your phone writes it even with no signal. Ask your results in plain words, like "what's my best lap here this month?" Every fault code gets a plain-words line saying what it means. Organizers get a day recap to send the crew. When you have signal it uses Apple's Private Cloud Compute, and nothing comes to us. On iOS 27 your crew's times also fit an extra-large home screen widget.

SEE WHAT YOUR MACHINE IS DOING Plug an inexpensive Bluetooth adapter into your machine's diagnostic connector and your speed, RPM, and engine vitals show up right on the timing screen. Most side-by-sides don't have the 16-pin car-style OBD port, and they don't need one: TrailTimer reads Polaris, Honda, Can-Am, Yamaha, John Deere, Kawasaki and other powersports machines off the connector they do have. Some machines need a pigtail cable to reach it, and some can't be read at all. Our site lists which machines work and which never will.

FIND A LOOP NEAR YOU Search public trails and published courses around you, preview the terrain in 3D, and import one in a tap. In national forests you'll see which machines the Forest Service allows on a route, and when. Public trails come from OpenStreetMap, so check land access before you race.

BUILT FOR RACE DAY WITH YOUR CREW You're the one who organizes it AND the one trying to win it. Line up the running order, watch riders on a live map while you wait your turn, and see times land on the leaderboard the moment they finish.

BUILT FOR THE TREES Trees, canyons, and jacket pockets make other GPS apps struggle. TrailTimer shows you honest signal health before you launch, and if the signal blinks mid-run it recovers the missed checkpoints in order when it comes back, instead of throwing the run away.

GLANCE WITHOUT UNLOCKING Your running time, checkpoint count, and gap to your personal best stay live on the Lock Screen, and in the Dynamic Island on iPhones that have one.

RELIVE EVERY RUN IN 3D Watch a flyover of your run over real terrain, with the actual line you drove and an elevation profile of the climb.

RESULTS THAT SETTLE IT Leaderboards, split times, personal bests, and head-to-head comparisons, with like-for-like class filters so a 250 two-stroke isn't racing a 450.

FOR THE BUILDERS: DIY CHECKPOINT TIMING Build the TrailTimer reader for about $250-350 in parts: one USB-powered unit that rides on your machine, with an antenna on the side. Then mark the course with cheap waterproof RFID tags. Every tag you pass is clocked automatically, out of sight of the start line: transponder timing like the big races run. Nothing to buy off the shelf yet; the build guide is on our site.

WORKS WAY OUT THERE No cell signal needed. Everything works offline in the dirt and syncs when you're back in range.

WHAT YOU NEED • An iPhone. That's it: GPS timing works with no extra hardware. • Optional: a Bluetooth OBD adapter for live gauges and fault codes

Free to time, score, and share. Your last 30 days of results are free.
