Engineered for Group Analysis

Reconstruct race tactics and club rides with geographic truth.

Unified Geographic Replay

Watch all riders move in real time across a unified course. Dynamic time gaps and distance deltas reveal exactly when the split happened.

Second-by-Second Telemetry Sync

Overlay power, heart rate, cadence, and speed curves. Uncover the physiological cost behind every attack, bridge, and counter-move.

Segment & Climb Breakdown

Automatically detect decisive climbs and sprint segments. Compare sector times, elevation gradients, and pacing strategies side-by-side.

Simple Workflow

Three steps to truth

01 • Setup

Create an Event Room

Generate a private event room with a custom route. Share the invite link with your ride group or race field.

02 • Ingestion

Sync Your Activity

Connect your Strava account for 1-click imports, or drag and drop raw .FIT and .GPX files from Garmin or Wahoo.

03 • Analysis

Relive the Race

Timelines align to the start line. Scrub the timeline, inspect telemetry at key attacks, and export highlight clips.
