Google Keep lets you make checklists and it's easy to uncheck everything on the list. I use it to make "leaving the house" lists etc.

I tried Keep a few years ago and I'm pretty sure this option wasn't there and needed to uncheck all items. I gave up at the time.

I just reopened it after reading your comments and found this "uncheck all boxes". It looks like you improved my life, thanks :)
