just purchased the F3B app. incredibly complex to install, activate, pay for, probably simpler to navigate a submarine than use this app. will try it out tomorrow in a lake and post comments on how well it works or does not.
I just finished a swim using the FSB app. It stopped recording after 20 minutes into a 40-45 minute swim. The GPS shows me as having gotten 1/2 around but not back to the parking lot!. This is after spending about two hours trying to get the software activated. This may have happened because the FSB software was still in trial mode. In any event, I do not recommend this complex -to-install and -use software. It does not solve the watch deficiency for open water.
