I use EZchecklist™ on my laptop most of the time, but it sure comes in handy on my iPhone too. However, it's a lot of poking around to open the Drive app, then go looking for my EZchecklist™ file and then open it.
So I finally got around to adding a "shortcut" to it on my home screen.
It's much easier now! And it's easier, then I'll use it more, and if I use it more then I'll build good habits faster.
