Moov now coach for run/walk, cycling, swimming, cardio boxing. Pairs with app. Can be worn on ankle for running, tracks motion and gait. Coaches on how you run, including pace, stride length and impact. Swimming tracks laps in pool and strokes. Cardio boxing gives a tough cardio workout, can be paired with a second for better tracking of workouts. Battery life is up to 6 months and it's fully waterproof. Just added a new battery. Comes with 2 bands one for wrist the other for ankle. I have a second which I'll thrown in but unfortunately one of the battery contacts snapped when changing battery. Maybe able to get a replacement or can be used for spares. I really enjoyed using this tracker but I'm no longer running and swimming now. I mainly wore the black (broken) one so this one is like new.
