Serpin
See your whole squad, live on the road.
Athletes stream live power, heart rate and GPS from their own sensors. Coaches watch every rider on one map — and send a nudge the moment someone drops or redlines.
Built for cycling teams, run squads, tri groups & training camps.
One app for the athlete and the coach
Existing tools are indoor-virtual, solo-outdoor, or async. Serpin does live outdoor multi-athlete monitoring — with intervention.
Power-first metrics
Serious training runs on watts. Serpin leads with power and %FTP, with heart rate and cadence as backup — because HR lags real effort by 20–30 seconds.
The whole squad on one map
Every rider's position and effort, updating live. Spot who's off the back, who's in the red, and who has stopped — at a glance, from the team car.
Any standard sensor
Connects to standard Bluetooth HR straps, power meters and speed/cadence sensors — Polar, Garmin, Wahoo, Coospo and more. Bring the kit you already own.
Coach-to-athlete nudges
Send a short suggestion to a single rider — "ease up", "bridge across", "you're dropping" — delivered straight to their screen mid-session.
Works in dead zones
Rural and mountain roads drop signal. Serpin buffers telemetry on the device and syncs when coverage returns — nothing is lost, everything replays in order.
All-day sessions
Engineered for 2–4 hour rides. A background service keeps streaming with the screen off while sipping battery, so it's still alive at the finish.
Made for athletes and coaches
The defining scenario: a moving, spread-out group with a following coach.
Ride. Stream. Focus on the effort.
Pair your sensors once and they reconnect automatically. Start a session and your live data flows to the coach — hands-free.
- Auto-reconnect to your HR strap, power meter & cadence sensor
- Live dashboard: HR, power, cadence, speed, distance, laps
- Join your squad's coach with one tap
- Receive suggestions without breaking rhythm
Watch everyone. Act on the right rider.
Follow the whole group live from the team car — position plus effort for each athlete, with alerts when it matters.
- Live squad map with per-rider position & intensity
- Alerts: rider off the back, in the red, stopped or dropped
- Last-known state & staleness when a rider goes offline
- Push short suggestions to any individual athlete
From strap to team car in three steps
Pair your sensors
Each athlete's phone reads its own Bluetooth sensors locally. Pair once — they reconnect every time you start a ride.
Start the session
Hit start and your power, HR and GPS stream live to the squad — buffered on-device through any dead zones.
Coach watches & guides
The coach sees the whole squad on a live map, gets alerts, and sends targeted suggestions in real time.
