I dont often rate apps, but this is a really great one. It has helped me add several new habits into my daily and weekly life, things I dont want to clutter my task manager with (i.e. Take pill, floss etc.)
the interface is simple and intuitive and it lets you track your "unbroken chain" and how many days/month you have done something.
Its really great, thank you!
