So I've got the Pro version of this app so that I can run without taking my phone. Things I've noticed. 1. The start running/walking indicators seem to be a few seconds late compared to the actual time on the watch. The beeps are always a few seconds late - anyone else found this? 2. How can I get the half way marker to play on my watch? I haven't tried running the app on my phone but I understand that it beeps when half way. How can I get the watch to do this? Thanks!
