When you swimmers arrive late, but you still want to track their training, you'll need to add them to an ongoing session, which is easily done. Here's how.
when a swimmer comes on deck with their unit after practice has already started, it's simple to add them into the workout from either a tablet or a phone.
Simply tap on the add athlete icon in the top middle of the tile view you are looking at. Scroll through the list and select the swimmer and tap "add athlete". This will add a new tile for them, and they can hop in and start the workout.
Click thein the upper right corner of the tile screen, and select add athletes. Same as above, simply scroll through the list, select the swimmer, and tap add athlete. This will add a new tile for them and they can hop in and start the workout.
