Double Check is a reusable checklist app for Android and Wear OS. It is built for lists you run through again and again: groceries, travel packing, morning routines, event prep, lab steps, or any task where a standard to-do list disappears too quickly.

Instead of rebuilding the same list every time, check items off, reset the list with one tap, and use it again. Your lists stay local by default, and sharing or Explore features are only used when you choose them.

Key Benefits

• Reusable lists: reset all checkmarks and run through the same checklist again.
• Wear OS access: check items from your wrist when your phone is not convenient.
• Home-screen widget: mark items directly from your phone home screen.
• Simple sharing: send a list by URL so another person can import it without logging in.
• Offline first: lists are stored on your device unless you share or browse Explore.

Manage Lists Simply

Create lists for repeatable tasks and keep each item visible after it is checked. Double Check keeps the workflow focused on preparation, verification, and reuse.

Reset and Reuse

When you are ready to use the list again, tap Reset to clear every checkmark at once. This makes Double Check a better fit for recurring checklists than one-time task managers.

Wear OS and Sharing

Use Double Check where the checklist is most useful. Check items from your watch while shopping or packing, then share a list by URL when someone else needs the same checklist.

Restore Deleted Lists

If you delete something by mistake, the trash bin helps you recover it. This keeps reusable checklists safer while still letting you clean up old lists.

Best For

• Shopping: reuse the same grocery list and check items from your watch.
• Travel: reset your packing checklist for every trip.
• Daily routines: track morning, workout, medication, or shutdown routines.
• Shared prep: send a ready-made list to family, friends, or teammates.

How to Get Started

1. Create a checklist for a repeatable task.
2. Add the items you want to verify each time.
3. Check items on your phone, widget, or Wear OS watch.
4. Tap Reset when you want to use the list again.

Double Check keeps the workflow simple: create a list once, check it often, and reuse it whenever the same situation comes back.
