Zwift
Never run alone Free (subscription required)
Whether you love to run, ride a bike, or both, Zwift turns your real-life activity at home into a global gaming experience. Connect with other exercise enthusiasts from around the world and never run or ride alone again!
Best of all, the action can now take place on your television screen, thanks to Apple TV support. Connect a trainer, power meter, or other sensor hardware and turn your riding, racing, and training into a virtual game that takes place at exotic locales any time of day.
Using the free Zwift Mobile Link companion app, Bluetooth-connected devices including Apple Watch become a game controller capable of capturing and displaying real-time heart rate.
The tvOS app updates you on what riders nearby are up to, as well as how many calories are being burned and how long you’ll need to work out per mile. There’s a seven-day free trial, then it’s $14.99 per month.
