OhSnap BMX: Gate Trainer
Start Reaction Timer & Sprints
Only for iPhone
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
iPhone
Your gate start is decided in the first 200 milliseconds. Train that moment anywhere with your phone, then take structured sprint sessions on the bike.
Practice BMX gate reactions off the bike, then take guided sprint sessions onto it. Reaction training needs no gate, no track time and no bike. Just your phone.
REACT TO THE REAL CADENCE
The full four-light tree with the authentic BMX cadence and an unpredictable wait every single time. The first red light and beep start the clock. React by tapping the screen or by moving the phone, and see your time the instant you move.
FIVE GATES. ONE SNAP SCORE.
The 5-Gate Challenge puts five starts together and scores them as one run. Snap Score weighs your speed, your consistency, how clean your gates were and how you handled the last one, so one lucky snap and two jumped gates does not beat five solid starts.
TAKE IT ONTO THE BIKE
Sprint Training builds structured ground and roller sessions out of sprints, rest and recovery. Starting lights, spoken coaching in four voices, hands-free intervals, saved workouts and full session history. Pair a Bluetooth speed or cadence sensor for wheel speed, leg speed and distance, or mount the phone for estimated force. Phone-derived force and speed are training estimates for comparing your own sessions, not laboratory or power-meter measurements. Sensors and mounts sold separately.
WATCH YOUR FIRST MOVE IN SLOW MOTION
Every start records an animated slow-motion replay. Run it against your personal record, your session best, your previous start or a target ghost, and see exactly where the time went.
PRIVATE BOARDS WITH YOUR CREW
Create a friend board, share one link, and race the people you ride with over a seven-day round. Fastest Time, Snap Score, or both. Everyone on the board reads the full standings, with no paywall between friends. Invite by link, QR code, or private rider code.
A NEW RACE EVERY WEEK
Five qualifying challenges put you on the public board, and it resets every week so the race stays live. Rank on Fastest Time or on Snap Score. Tap and Shake rank separately so the timing stays fair, and every ranked result shows the platforms behind it. Chase the rider directly ahead of you, not the one 700 places up.
SHOW UP EVERY DAY
Bank your Daily Five, build a Snap Streak, and earn Rain Checks that cover you when life gets in the way. Milestones at 3, 7, 14, 30, 60, 100 and 365 days.
A TROPHY ROOM TO FILL
Speed, control, mastery and milestones, plus secrets you have to find and bloopers you would rather not earn.
KNOW WHAT IS ACTUALLY IMPROVING
Personal bests, current form, tier breakdowns, consistency and your full attempt history. Every number traces back to a real start you took.
STARTS FREE, WORKS OFFLINE
Unlimited single gates, Daily Five, streaks, trophies and three 5-Gate Challenges a day are free, and reaction training runs with no account and no signal. Reaction+ adds unlimited challenges, full stats and history, leaderboard visibility and friend-board creation. Sprint Pro adds the complete on-bike training suite.
Listen. Watch. Snap.

Timing fairness
Shake reaction times on iPhones with 60 Hz displays now include a small timing adjustment so they compare fairly with 120 Hz phones.
