iPhone

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. TrailTimer Pro keeps your full history forever, publishes unlimited tracks, and adds gauge notes to your debrief, a season review for each course, and the post-run deep dive. Subscribe (with a free month) or buy it once to support a fellow side-by-sider.

THE DEBRIEF IS FREE NOW All of it. The story of your run, the note on each leg, and the tip for next time, for everyone. Finish a run with no signal and your phone writes it. Once you're back in signal it gets a better write-up, and your times and PBs stay exactly what you heard at the line. ASK YOUR RESULTS "What was my best lap at the loop this month?" Tap the sparkle on Results and ask in plain words. It answers from your own runs. GAUGES & CODES, ONE SCREEN Adapter setup and the Code Reader are now one screen, Gauges & Codes, and it tells you up front what your machine can give: gauges, codes, or both. When you've got signal, each code gets a line under it saying what it actually means. It still won't tell you what to replace. That's your dealer's call. A BETTER CALL AT THE START LINE The start-line call is ready before you lose signal at the trailhead, it knows which direction you're running, and if a friend holds the fastest lap in your class it tells you the time to beat. DAY RECAP FOR ORGANIZERS Close out a group day and you can send the crew a recap: every course, the fastest times, and who set their first time. Free. FOR PRO Plug in your adapter and the debrief adds a line per leg from your gauges: where you were flat out, how high the RPM went, how hot it ran. And once you have five runs on a course over three days, Results offers a season review: which legs are getting quicker, which aren't, and how you stack up against your friends on each one. FOREST SERVICE RULES, RIGHT ON THE COURSE Import a trail or open one of your courses in a national forest, and if it follows a Forest Service road or trail you'll see which machines are allowed on it and when, straight from the Forest Service's own map. Riding outside the season? You'll see that before you hit START. STUCK ON "ACQUIRING GPS"? If GPS sits there at the trailhead, the app now tells you the thing that usually fixes it: Airplane Mode on and off in Control Center. Plus: an extra-large Friends' Runs widget on iOS 27, the rider dot on the map uses the app's own GPS so it can't get pulled onto the nearest road, guided gauge setup stops offering you a signal you already said was wrong, the first callout no longer freezes the countdown for a beat, the 3D flyover isn't too dark anymore (forests were coming out black), and Discover keeps trying when the trail server is busy instead of coming up empty. Ask, the recap, the Pro write-ups and the code lines need an iPhone with Apple Intelligence turned on. Keep the field reports coming. Setup › Send Feedback goes straight to me.
