Got Time

With got time you don't have to worry about remembering things you cannot do at the moment. If there is something you have to do whenever you have time, you can just add it into the app with an estimated duration. Once you have some free time you let the app know and you will see all the tasks you could accomplish in that free time. It is not just another to-do list app. Got Time targets specifically those tasks that it seems that you never have time for them.
