Reminders don't pop up if the app isn't open such as clearing all open tabs or if you haven't opened it at all in a day. I think that's why the app should be for, remind you because you may not have the time to. It's a good app but pls I'd like that this be worked on. I would also be nice if you can permit the option to pick alternating days or weeks as frequency of a task may not fall under weekly or daily. (e.g Tuesday, Thursdays and Saturdays).
