Timer, stop and start buttons are too small when doing exercises.. Also get rid of the message ikon during exercises it's only in the way..

The app needs to have bigger buttons for starting the workout, ability to make the timer a larger portion of the screen, and just overall bigger font without compromising on the experience. I have decent eyesight but struggle to see things well at a glance on the app so I can only imagine that others are struggling with this same issue. And a lot of the buttons are difficult to press unless you have teeny fingers

Make the time clock for countdowns and stop watch larger. It is sometimes difficult to see unless I prop it really close by.

I shouldn't have to keep trying to select the slider button to rewind the video or hit the timer button again and again. They are too small. Make them larger or more sensitive.

Bigger buttons for start and stops. I'm wearing gloves, this isn't easy.

Make the timer larger so it is visible from a distance. Then you can see it while doing your exercise without having the phone next to you.

A large countdown clock that allows you to change the duration while you are in the workout schedule
