CheckOne
Run a checklist step by step
Free · In-App Purchases · Designed for iPhone. Not verified for macOS.
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.
