ToDo is a minimalist task and list manager and reminder for you who wants to know what and when you have to do something. You can create a list of tasks for a specific category, like University or House tasks with deadlines, notifications and importance indicated by color. You can also create a list with simple items as a Wish list or groceries.
This app has a Dropbox integration option, so if you have 2 or more devices you can sync all your lists between them!
