Deadline Guardian

Deadline Guardian is your hub for everything that recurs in life – inspections, services, insurance, vaccinations, contracts. Create a device (car, home, pet), add a deadline, and the app warns you in advance – up to 30 days ahead on legal templates. You set the lead time per item, even on the due date itself. After completing it, log the supplier, cost and a photo of the receipt – the app calculates the next due date.
