TimePage needs access to the default Calendar app and the Reminders app (at least in my case). However, I want to use the app independent of either app. My intention is to have a planner for a work day, school day, and free day. Therefore when I know my calendar, I can set each day to a particular planner. A bit hard to explain, but I can definitely see more people use this app for that, AND I’ll be willing to pay for a subscription.
