How to create a Checklist on your iOS Device
Open the Notes app on your iOS device and compose a new Note, or open one that already exists. Tap anywhere in the compose section and you will see a plus icon appear – tap it.
This will bring up the formatting options where you’ll see the checklist icon on the far-left. Once you tap the icon, a blank checklist button will appear where you can type in your task. You can also move the cursor next to an already listed item and tap the checklist button to create a mark. To mark an item as done, simply tap inside the empty circle.
The Notes app is great on both iOS and Mac OS X. So if you are looking for a checklist app in the App Store, don’t bother. Notes is free, simple to use and comes with additional features that transfer easily from multiple devices.
