I like this app. It makes keeping up with my to do lists easier when I'm on the go. Keep in mind it is a very simple list making app so don't expect a lot of specific dates, etc. It's divided into Today, Tomorrow, Someday, etc. so what you put on your list for tomorrow will automatically move from Tomorrow's list to be on Today's list the next day. I keep my grocery list in the Someday section simply so it will not move up a list and eventually in to my Today section. I've used this app on an iPhone 4S and am currently running it on an iPhone 6.
