Sure. Well every to-do app has most of the functionality you need (Wunderlist is the one I like the best). They have annual reminders so you can put a checklist for taxes or something. BJ Novak has https://li.st/bjnovak/ https://li.st/bjnovak/ which is a general list sharing app. It has the social component that I think would be very useful applied to to-do lists. Finally, there are ready made list apps which help you maintain your home, health, car, kids, wealth etc. I wish there was a social market place like li.st for apps like Wunderlist with multiple lists to choose from.
