Just ordered the FitBit Flex 2. I'll give a shot. If provides me the basic swimming info (laps/distance/time/calories) accurately, that will be enough for me to pass the AW2. For $100 sounds great and I can keep using my Omega Seamaster.Either one should do great for that, but I would read the reviews carefully. Most swim trackers seem to do freestyle well. But, breast stroke has given some trouble.
