I’ve been using Flow for a couple of weeks now and loving it. The main reason I love it is it is individual-centered and not company-centered. My wife and I can each have an account and share a project called “home" as well as share other projects with people who I am working with.
There are many little details throughout the app, but this one made me smile. You can enter “today", “tomorrow", “1 week", “3 days" as the due date and it will automatically figure out the due date.
