Description by Mishima Design Written by the developer, not by AppBrain. Click to read.
CheckOne shows checklist items one at a time so you can confirm everything without missing anything.

Create checklists for things you want to confirm in order, such as before going out, travel prep, leaving a hotel, before a meeting, gym items, morning routines, or bedtime routines.

Instead of looking at a long checklist all at once, CheckOne shows the current item clearly and lets you move forward as you check each one. It helps you focus on the next thing to confirm.

CheckOne also supports Apple Watch. You can view checklists, start a run, check items, and keep the run state in sync with iPhone.

Templates are included so you can start quickly, and you can also create your own checklists from scratch.

Features

- Create and edit checklists
- Create from templates
- Run a checklist one item at a time
- Move items later and optionally save the new order
- Choose checklist colors
- Sync run state with Apple Watch
- Haptic feedback while checking items
- Double Tap support on Apple Watch

CheckOne Plus

CheckOne Plus unlocks every feature with one purchase, including creating multiple checklists, choosing any color, and moving items later.

Note: Double Tap is available on supported Apple Watch devices with watchOS 11 or later.
