Completely random
I have been looking for a reliable swimming app for the Apple Watch for a while and I was hopeful with this one, but unfortunately it is not that good. In a 5x200m free style test work out, not a single one of the sets was reported properly. While distances were accounted for (except first set, which showed 175m), the stroke identified were almost all wrong (backstroke) and the timing was way off (3:30 average pace was reported anywhere between 3:45 and 7:00/100m!!). Very disappointing.
