Great and ease to use
Tried out several apps to improve the running cadence. This is one definitly the best: saves the cadence over different sessions and, best of all, runs in the background. You can use a running app simultanously and switch of the screen, choose between different sound and control volume. Great cadence range up 180 bpm. All in all: to be highly recommended
