found this at just the right time ??? – Reminder & Countdown Pro Review

Love this app! Never been too much into reminders, but really need them at the moment. This app is lovely and fun, with lots of creative choices, which is my favorite part (although you don’t have to use those possibilities if you don’t want to). I made a couple of dozen reminders right away, and will be adding more. One small problem: I was sorting in “customizable” mode, and several times, after moving a reminder up or down, the reminders became untappable for editing. Fully exiting the app solved it each time and no reminders were lost. I’m on a semi-old iPhone, which may be why it happened. Still worth all five stars to me.
