This is an updated listed (Sept. 8, 2016) with some I know (evernote) and some I don’t know. (Forest) What intrigued me about Forest is that it is an app to help you stay off your phone, while you are supposed to be studying. You set the task and the time. Then if you try to use your phone, your tree dies! But if you complete your task without getting tempted to use your phone, then you get badges and your can build your forest!!!!
OK, you can also try RefMe, which lets you scan the barcode of the book you are using for your research paper and choose the citation format, like APA and it will put it in the correct format for you, without having to type all the info in!
