I LOVE the Doo app. I got it when it first came out & I really appreciate it being both Mac-iphone and the simplicity carries across the too platforms seamlessly. I actually use Doo as a companion app to a heavier GTD app. I manage the big picture of my life in those apps but I use DOO app for the things I need to do for a single day only. Doo is so helpful because its so easy to swipe through and not get overwhelmed by the heaviness of the bigger apps. Its light, simple, beautiful and ridiculously inexpensive for keeping a person sane. Thanks to the developer for making this so easy to use and for continuing to develop it. Its a beautiful app and it’s simplicty is why I use it to actually get things done.
