What it does

• Build your own ridesSet the length, resistance, position and cadence of every interval, and see the whole ride as a colored chart, from easy green to hard red.
• Ride with cuesA big countdown for each interval, your total time elapsed and remaining, and a “Change resistance to 45” warning with beeps before every change.
• Plan your weekPick a ride for each day. The app opens on today’s ride with a big Start button, and shows what’s coming up.
• Adjust on the flyToo easy or too hard? On a tablet or phone, drag the resistance up or down mid-ride and the app saves an adjusted copy.
• Works offlineAdd it to your home screen and it runs like an app, with or without an internet connection.
• Free, no accountYour workouts stay on your device. Optional sync keeps them the same on all your own devices.

It runs in your web browser on a phone, tablet or computer, so there's nothing to install. Openspin.paulgeorge.com, and on an iPhone or iPad useShare → Add to Home Screen to keep it one tap away.
