Tripper GPS

Telemetry that knows your bike, not just your phone. Calibrate to your mount, then log route, lean, grade and g-force at 100 Hz. All on-device.

Tripper turns your iPhone into a proper telemetry logger for motorcycles, bicycles, and cars. Mount it, tap Start, and ride. Everything else is recorded for you.

CALIBRATED TO YOUR BIKE, NOT YOUR PHONE

Most apps measure motion in the phone's frame, which is meaningless when the phone is clamped to your bars at an angle. Tripper measures it in your vehicle's frame. Tap Reset Angle once and the current orientation becomes zero, so slope, lean, and g-force are read along the axes that actually matter: forward, sideways, and up. Level ground reads 0 degrees no matter how the phone sits in its mount.

WHAT IT RECORDS

• GPS route, speed, distance, and heading • Barometric elevation, fused with GPS - far smoother than GPS altitude alone, so real hills survive and noise does not • Road grade, as a rolling window rather than jittery point-to-point noise • Lean angle and slope in your vehicle's frame • G-force: braking, acceleration, and cornering, measured in the horizontal plane the way motorsport telemetry does, with the vertical jolts from potholes filtered out instead of inflating your numbers • Up to 100 Hz motion sampling, logged at the rate you choose

BUILT TO BE USED AT SPEED

The dashboard floats over a fullscreen map: big numbers, high contrast, readable at a glance with gloves on. The controls are deliberately hard to get wrong - a stray tap can never end your ride, because finishing is only possible from a paused state.

It keeps recording with the screen locked, and you can pause, resume, or drop a marker straight from the Dynamic Island and Lock Screen. Or from your wrist: the Apple Watch app shows duration, speed, altitude, and your position on the map, and lets you start, pause, and mark a ride without ever touching the phone.

FOR VIDEO OVERLAYS

Drop a marker at any moment - a clap, a landmark, a starting gun - and it is written into the data with an exact timestamp, so you can line the telemetry up against your action-cam footage frame for frame. Exported CSV is shaped for overlay tools like DashWare and Telemetry Overlay.

AFTER THE RIDE

• Replay any ride full-screen: scrub through it, or play it back and watch the dashboard come alive over the map exactly as it was • Speed and elevation charts, with distance, moving time, average and top speed, elevation gain, and peak g • Overlay past tracks on the live map and go and chase them • Import rides from .trip, GPX, KML, or CSV • Export full-telemetry CSV, GPX with telemetry extensions, or a compact .trip archive

ENTIRELY YOURS

No account. No cloud. No analytics, no advertising, no third-party SDKs. Every ride is processed and stored on your device, and nothing leaves it unless you explicitly export or share it.
