When you have a question, you don't always google it immediately. Remember, how many times you've been telling yourself: "I need to look it up later"? In many cases, when finding an answer to your question takes some effort on your part, you tell yourself you are going to do it later. And then you forget about it. Maybe you need to read a particular book or watch some instructional video and you don't have time for it right now. Or maybe right now you just don't feel like doing anything about the question that bothers you. But you don't want to forget the question!This app allows you to keep a list of things you want to learn in the near future. Whenever you find an answer to a question you can 'Check!' the question, which will send it to another list called 'Things I Know'. That's how you monitor your progress. You can delete or edit any of the questions in both lists.
