Design is simple and clean, also flexible with ability to move different items around on list as well as organize various items into separate lists. Layout allows me to quickly jot down new reminders and checklists while Im out and about. Google sync ability makes it that much better, too.
Ive been a loyal user for +4 yrs, but the only reason Ive given 3 stars and not 5 is because the app has not fixed this annoying bug for well over 2 years-- Every time I launch the app, it freezes and I have to quit out and relaunch it EACH TIME I want to use the app in order for it to work. (iPhone 6S, this bug has occurred from iOS 9 to current iOS 10.3.2)
