Xert EBC 4+

Xert have unique analytics, aimed to optimise training and determine your fitness signature (power vs time, max power available). The fitness signature is continuously updated. I'd say the analytics are geared towards short, high-intensity, above threshold training. The system is very motivating for that kind of work, and recommends workouts to achieve user-specified goals. I do a bit of that, but I'm not sure their analytics work well for longer endurance training, where there is little above-threshold efforts.

I got the app because it could connect to one side of a Favero power meter pedal using Bluetooth. The app works as a pretty decent bike computer. It's missing a lap function, and the average power drops during stops (which may be fine for short high-intensity sessions, but I don't think it's helpful for >5hour rides). The app uses about 15% battery per hour on my iPhone X, so can get a 6 hour ride in pretty easily, and that's with the screen on (using the auto-dim function). If it had a lap function, and configurable screens, for outdoor rides, it'd be close to 5 star for me I reckon

Love that it has all the workouts ready to go and linked with my power meter easily (Garmin Vector). If only they didn’t use colours that can’t be seen in sunlight and chimes that can’t be heard when riding outdoors.

XERT is ahead of the competition when it comes to mixing science and functionality to training on a bike . The signature is unique if not surprising when you review the results , that’s because they are talking a slightly different language that we have been talking in under conventional normal training approaches
