Aside from bills, maybe also consider some kind of personal renting app? For example, if my neighbor wants to borrow my lawnmower, your app could help set up the due date, automate the reminders, and maybe even take care of compensation?

Along the same train of thought, if someone owes you money, maybe have this handle the amount, terms, and reminders for the borrower (small amounts)?

Personally, I'm not the type of person to hound someone for either of the aforementioned items. I think that'd be a neat service.
