content: I have ADHD and this app really helps me to organize and structure tasks i regularly forget. I havent run into a situation where i would need to upgrade to the premium service. You can schedule things to happen every set amount of time i have one to remind me to clean my pets cage every 2 weeks. You can make different categories so I have work school groceries home. You can also schedule something for a specific time or date Very useful when i think of something i need to do later.
