In reply to Nevis-the-cat:
I've just signed up to the 30 day free trial, if you decide to keep after that period they invoice you monthly, which makes it more affordable too.
Premium subscription is free with the pro model and the software is pretty good, data can be exported and imported i.e. Garmin files from Outdoor rides, to include in your plan.
During my session yesterday the app went "offline" but when I'd finished the ride, the data was there and hadn't been lost.
Premium subscription also offers "all you can eat" and you can upload your own video/gps rides, unlike the Tacx were you have to buy a PC link, individual videos etc. I sent my Bushido Smart back, it was impossible to pair / calibrate and crashed frequently.
