TrainerDay Squad
Train together, in one room
TrainerDay Squad puts every rider's smart trainer on one big screen. Made for clubs, classes and teams that sit side by side, with a coach running the session.

How it works
From an empty room to a group ride in a few minutes.
Connect every trainer
Pair the smart trainers over Bluetooth or ANT+, then add heart rate straps if you have them. The app remembers who rides which trainer.
Pick a workout
Choose a built-in kids workout, one of the included TrainerDay workouts, or drop in your own file. Or skip the plan and set the watts by hand.
Ride on one screen
Put it on a TV or projector. Every rider sees their own power, target, heart rate and place in the group.
Built for a coach and a room full of riders
It started with kids aged 8 to 11, so everything is big, bright and easy to read from the bike.
Made for young riders
Big numbers, a colour and an avatar for each rider, points during the ride, medals and awards after it.
The coach is in control
Change the intensity for everyone or for one rider mid-ride, pause the plan, or take over and set the target yourself.
Fair for every level
Give everyone the same watts, or scale the workout to each rider's FTP so the strongest and the newest work equally hard.
Join or leave any time
A late rider joins without stopping the ride. A dropped Bluetooth connection reconnects by itself.
A podium after every ride
Results, group awards, personal bests and fun facts about what the team did together. Every ride is kept in the history.
Six languages
The app runs in English, German, French, Spanish, Italian and Russian.

Free, and your data stays with you
We built Squad to help groups train together better. It is a community project, not a product we are selling.
Free to use
No price, no account and no subscription. Download it and ride.
Everything stays local
Rider profiles, workouts and ride history are stored on your computer. The app does not send them anywhere.
Open source soon
We are preparing to publish the source code so clubs and developers can see how it works and improve it.
We have no plans to charge for the app. Later we may add optional paid cloud features for those who want them.
