Ever wonder when you last changed the air filter? Watered the plants? Cleaned the gutters?

Tasks on Time shows you exactly how long it's been since you last completed recurring tasks — and nudges you when they're overdue.

Unlike to-do lists that focus on what's next, Tasks on Time focuses on what's been waiting. Live timers count up from your last completion. Cards change color so overdue tasks can't hide.

How It Works

Create a task, tap to mark it done, and Tasks on Time starts counting. Set a threshold and the card shifts from green to amber to red as your deadline passes. That's it. No complicated setup, no accounts, no subscriptions.

Features

• Live elapsed timers: see days, hours, or minutes since each task was last completed
• Color-coded urgency: cards shift from green to amber to red as tasks become overdue
• Custom color cards: choose from 10 colors to organize tasks your way
• Sections & categories: group related tasks and collapse sections to stay focused
• Drag to reorder: arrange tasks and sections in the order that matters to you
• Smart reminders: get notified relative to when you last completed a task, not on fixed dates
• Nag mode: repeated reminders until you actually do the thing
• Completion history: see when you did each task and add optional notes

• Import & export: back up your data as JSON or move it to a new device
• Dark mode: full light and dark theme support with Android 12+ dynamic color
