If I subscribe on PC, do I have to pay again for the iOS version?

This question comes up quite a bit in the Zwift Riders Facebook group and other forums.

The short answer is No, you do not have to pay again once you're a member of Zwift. Once you've subscribed, you can log into any device at any time with that account, and there are no additional charges.

Your monthly membership fee includes the use of Zwift on any and all devices you wish to use it on, whether they be PC, Mac, iOS or any future device they begin to support.

This is no different than using services like Dropbox, Evernote, Skype and others, where you are interacting with an online suite of services with a locally-installed client on your desktop, laptop or mobile device; you pay for access to the service, but are able to use it with any device where the app is installed, for the same fee.

So subscribe now! Hook onto a ride or Zwift event, and #RideOn!
