Xert

For riders who enjoy the numbers more than the scenery. Xert models your fitness from your power data and picks workouts to match, and its EBC app runs them on a smart trainer. That makes it a cheaper alternative to TrainerRoad for data-driven training, at $14.99 a month or $99.95 a year after a 30-day free trial. Xert has no virtual world of its own, though it can send its workouts to Zwift, Rouvy and MyWhoosh when you want scenery or company. It suits riders willing to learn its own fitness terms rather than those who want an app to simply tell them what to ride tonight.
