Ive been using Runtastic for a couple years now. I like a lot of its features. The watch integration was poor to begin with, but it improved quite a bit over time. Unfortunately, the latest version seems to be causing flakiness with the watch app again. Twice now the watch app has crashed. When I relaunch, it doesnt sync with the phone app to pick up the activity in progress, and the heart rate monitor gets stuck on until I reboot the watch. This kind of unreliability has me thinking of trying something else. I would also like more flexibility in what the watch app shows (like average pace instead of current pace).
