Structured indoor training sessions at home. Winter base miles without a virtual world. Tracking power and cadence on an iPad mounted to the bars.

"Not a virtual world" is a good pitch. Most of the big apps assume everyone wants Zwift, but plenty of people just want the numbers and a workout they can follow. As an iOS dev I'm curious how painful the FTMS resistance control was across different trainer brands, Bluetooth implementations tend to drift from the spec. Did you have to special-case many models?
