Overdue helps you stay on top of the recurring tasks that quietly slip through the cracks, from replacing water filters and mowing the lawn to seasonal maintenance and one-off chores you know you’ll need to revisit. Instead of juggling reminders in your head, scattered notes, or generic to-do lists, Overdue keeps a simple history of when things were last done, shows what’s overdue or coming up next, and makes it easy to organize everything by tags like Household, Yard, or different properties. - Track recurring household, maintenance, and personal tasks in one simple app - See at a glance what’s overdue, due soon, or recently completed - Record completion history so you always know when something was last done - Add reminders for scheduled tasks so important jobs don’t get missed - Search, sort, and filter tasks to focus on exactly what matters - View detailed item history, notes, status, and next due date - Manage and rename tags as your system evolves - Use Home Screen Widgets to keep an eye on the most important tasks
