Biopharma R&D by day. Swimmer and indie iOS dev by night. Built SwimLog because my Apple Watch knew more about my swimming than I did.

SwimLog - Fitness shows pace. SwimLog shows how to improve

Stop guessing after every swim. SwimLog turns your Apple Watch workout into clear coaching — SWOLF & stroke efficiency, auto stroke splits, rest intervals, heart-rate recovery, personal bests, open-water GPS, and a gear locker. Free on the App Store: open your last swim and see what Fitness never showed you.
