Very little competition…
Well it works with a Kickr and a Polar HR, you can build workouts within the app - this is quite well executed and it is one of the few apps within this price range without unnecessery features (it’s quite cheap). There is room for improvement, though: you should be able to raise or lower the power within a training or skip an interval for example. The graphical display would profit from a line- and barchart of the training. But overall, it one of the best options if you are looking for a cheap app where you can build workouts and train without the overhead of for example Zwift.
