Get the best out of your smart trainer. Ride structured workouts or re-live your outdoor rides from a recorded GPX file. Improve your fitness and measure your success.

With The Surge you can train with your indoor smart trainer starting at any level. Perform a test to determine your fitness and start working out based on your physical condition.

With structured workouts you can:
- Choose a training plan to reach a personal goal, to prepare for races, or to stay fit during the cold season.
- Ride your favorite workouts in a specific category whenever you want

When you want to have fun you can
- Ride at awesome places like Roubaix, Alpe d'Huez on Apple Maps – often in 3D
- Add your own routes from Services like STRAVA or from GPX files

When you have no idea you can
- Ride in target mode just as easy or hard as you want

All your trainings are recorded and can be shared to well-known services or exported as FIT.

The Surge uses HealthKit to export your workouts to the Health app and to read biometric data.

The Surge subscription is available as a monthly or annual subscription. Sign up and pay using your App Store account. Membership will automatically renew unless cancelled at least 24 hours before the current membership expires.
