I've got a side project that is a long-term reminders app. It has a long list of reminders included like changing the oil, test the smoke detectors, flipping the mattress, getting your prostate checked, etc. You could just go down the list and enable everything that applied to you. I kinda lost interest in it but one of these days I should dust it off and get in the app stores.

That sounds great! I plan to build such a reminder service for myself with additional infos like the subscription costs. How did you managed to show different categories/calendars and how did you do the repeating scheduling of events?

I just create a single calendar specifically for my app, then add things to it directly. Calendar events already support all of the repeated scheduling I needed. I didn't setup anything for categorization directly, but could be pretty easily done by prepending an emoji to the event name.

Right now I just set a calendar event (in Google Calendar) for the future. What's the repeating part? Typically I don't have to re-cancel my eg Netflix subscription once I've canceled it until I sign up again, at which point I set a reminder then.

What I'm really missing is the quick add by string that Google calendar used to have. Eg type in "next thursday at 8pm" and it would do just that, instead of laboriously having to scroll to next Thursday, then create an event and set it to start at 8pm.
