Adding other types of timers and the ability to use them during a workout. Currently, there is the rest timer and the exercise timer if the exercise is done for time.
Would be nice to have timer options like EMOM, AMRAP, TABATA, HIIT, etc.
Although the mentioned timers are mainly used in CrossFit, they can be useful for hybrid athletes as well. For example, sometimes I like to do EMOM for pull ups and/or dips at the beginning of an upper body workout.
