This app starts from an example in this tutorial, http://www.raywenderlich.com/77974/making-a-gesture-driven-to-do-list-app-like-clear-in-swift-part-1
then I will continue to integrate Promodoro technique to this to-do list
I hope this app can help you to plan your to-dos in a Promodoro ways, so I named this app as "toPromodo"
