In Swimmo firmware v1.2.4 and 1.3.0 and above what has changed is method to pause/end your workout. Since these version Swimmo watch is expecting double tap without arm motion to pause/end workout.
This was introduced to prevent accidential pauses during swim reported by small but significant number of users (approx. 5-10% before). Please read on to understand how it works.
Pausing your training
To pause your training with Swimmo, quickly double tap the screen to see Pause Screen with workout summary.
Please remeber not to move your arm when pausing the workout as we've implemented a motion lock to eliminate unintentional pausing during the swim.
If your watch doesn't respond at first, hold your arm steady for 2-3 seconds and then try to double tap.
Ending your training
Once you are in Pause Screen with workout summary, tap the screen again. Then rotate to the option "END", please tap the screen to select it and it should stop your training.
