Custom timer doesn’t work on Apple Watch


Just installed seconds and upgraded to pro. Created a custom timer which works fine on my iPhone X. The timer appears among the list of timers on my Apple Watch. However it won’t start when I tap it. (The other timers that come with the app work fine on my watch.) Help please.


This is usually an issue related to timers that have intervals with 0 durations. The iOS version of the app handles these by ignoring them, however, the watch app currently thinks it’s invalid and will not start the timer.


Thank you. Changed interval from 0 to 1 sec and that resolved it.
