Time Settings Won’t Keep

This is a great app! But I lowered my approval because the time settings won’t retain my chosen setting (I tried to mark a countdown of 1 minute 20 seconds, and it keeps revertting to the previous setting, despite saving by clicking the OK button) and also because new interface is not as intuitive as I would desire.
Fix the settings and I will give it four stars, and update the interface and it will be 5 stars.
