ChronoCheckPro

ChronoCheckPro is a GPS-powered segment and lap timer for mountain bikers, mx riders, trail runners, and anyone who wants precise, repeatable timing. Define gate lines on the trail, ride or run through them, and get accurate split times — automatically. Time point-to-point segments, or set up a loop track with lap and split timing. --- How It Works Instead of relying on a single GPS waypoint (which can miss you entirely at speed), ChronoCheckPro uses gate lines — virtual lines drawn across the trail. You define each gate by walking to the left and right edges of the trail and pressing SET. When your GPS path crosses that line, the timer triggers with sub-second precision thanks to time interpolation between GPS ticks. --- Key Features 1. Gate Line Detection - Define start and finish lines by walking two points across the trail - Line-crossing detection is far more reliable than point-proximity at speed - Time interpolation gives you millisecond-level accuracy even at 1 Hz GPS 2. Speed Gating - Automatic rejection of implausible GPS jumps that would cause false triggers 3. Multi-Segment Sessions - Create up to 10 named segments on your device - Select any combination for a timed session - Auto-advance: when you cross the finish line of one segment, the app automatically moves to the next — no button presses needed mid-ride 4. Track & Loop Mode - Define a track as an ordered sequence of gates forming a loop - Single gate = lap timing: cross the gate to start, cross it again to record the lap - Multiple gates = split timing: each gate-to-gate interval is timed independently - The finish gate of one split is the start gate of the next — no wasted gates - Crossing the start/finish gate closes the lap and immediately starts the next one — zero dead time - Up to 5 tracks with up to 10 gates each - Best times tracked per split and per full lap 5. Times History & Best Time Tracking - Every run is recorded (up to 50 per segment or track) - Best time tracked and displayed - Browse your full times history from the detail menu, including per-split bests for tracks 6. Haptic Feedback - Short vibration at start line or split gate, long vibration at finish or lap completion - Know exactly when the timer triggers without looking at your wrist 7. Live Display - Real-time elapsed timer during your run (updated every 200ms) - Distance to the next gate line shown in meters - Session progress indicator (e.g., "2/5") during multi-segment sessions - Split timer and split counter during track mode 8. Built-In Help - Scrollable Info section with setup instructions, session tips, and usage guidance — right on your wrist --- Setup in 60 Seconds Segments (point-to-point): 1. Open Segments → create a new segment 2. Walk to the left edge of your start line → press SET 3. Walk to the right edge → press SET 4. Repeat for the finish line 5. Start a session and ride! Tracks (lap/loop): 1. Open Tracks → create a new track 2. Walk to the left edge of the start/finish gate → press SET 3. Walk to the right edge → press SET 4. Choose "Add Split Gate" to add more gates, or "Done" to finish 5. Start the track and ride! All data — coordinates, names, and times — is saved to your device and persists across app restarts. --- Designed For - Downhill and enduro mountain biking - Motocross and enduro - Trail running segment timing --- Tips for Best Results - Set gate lines across the full width of the trail for reliable detection - Wait for a solid GPS fix (green indicator) before setting points - Use multi-segment sessions to time an entire course in one run - Use track mode with a single gate for simple lap timing on a circuit - Add split gates along a loop to identify where you're gaining or losing time --- Developed by Mauro Cocco.

What's New Track & Loop Mode (New) Track Mode — Continuous Lap & Split Timing Define a track as an ordered sequence of gates that form a loop. Place a single gate for simple lap timing, or add split gates along the course for detailed per-split breakdowns. The finish gate of one split is the start gate of the next, and crossing the start/finish gate closes the loop and immediately begins the next lap — zero dead time between laps. Single-Gate Tracks (Lap Mode) Place one gate anywhere on a circuit. Cross it to start the timer, cross it again to record your lap. The next lap begins automatically on the same crossing — just keep riding. Multi-Gate Tracks (Split Mode) Add up to 10 gates along a loop to break your course into splits. Each gate-to-gate interval is timed independently, and a total lap time is recorded when you cross the start/finish gate. Best times are tracked for each individual split and for the full lap. Reorganized Main Menu The main menu is now organized into three sections: Segments (point-to-point timing with sessions), Tracks (loop/lap timing), and Info. Everything is accessible in fewer taps. --- Initial Release Gate Line Detection System ChronoCheckPro introduces a precision timing approach purpose-built for high-speed GPS segments. Instead of the traditional "get within X meters of a point" method, the app uses gate lines — virtual finish lines drawn across the trail. Your GPS path is tested for intersection with each gate line on every update, and the exact crossing time is interpolated between GPS ticks for sub-second accuracy. Two-Point Walk Setup Each gate line (start and finish) is defined by walking to both edges of the trail and pressing SET. This creates a line segment that spans the full trail width, ensuring reliable detection whether you ride through the center or hug the edge. Speed Gating Built-in protection against GPS teleports: any GPS reading that implies movement faster than 180 km/h is automatically rejected, preventing false triggers from satellite signal errors. Multi-Segment Sessions with Auto-Advance Select multiple segments and time them in sequence. The app automatically transitions to the next segment when you cross the current finish line — no mid-ride button presses required. A session progress indicator keeps you informed of where you are. Complete Times History Every run is saved (up to 50 per segment). View your full history from the segment detail menu, with your best time clearly marked. After each run, see an instant comparison to your personal best. Haptic Feedback Distinct vibration patterns for start (short pulse) and finish (long pulse) so you always know when the timer triggers, even when you can't look at the screen. Persistent Storage All segments, gate coordinates, and recorded times survive app restarts. Pick up right where you left off. In-App Help A built-in scrollable Info section walks you through setup, running sessions, and tips for getting the most accurate results.
