EDIT 2021-10-31: I believe there's been a misunderstanding about the bug I was reporting: The prep timer starts at 60 (not 600) sec. no matter what time I set. This is why I couldn't even figure out it was counting down seconds, it starts with the wrong time no matter what you set. (That said I would be very interested in a config option for displaying the time in minutes and seconds. If the timer bug was fixed too.) - I would love the concept and features of this app... if it actually worked!

Hi, Update 2021-11-04: I would really like to figure out why it's not working for you. Can you please contact me via mail interval-timer@allworkouts.app. Thank you! The feature we were talking about will be available on the beta channel of the app soon. Best, Tobi
