excellent app to put order in any kind of documents you use. I personally like to work with hard copy papers or notes – the notes are just never where I am. Before I got to know this app I used take photos of the notes, resulting in a chaos in my media library. This app saves each document as a PDF, you can quickly give the file a name with the help of tags and store them in folders. All on your mobile phone. Also you can put more than one page in one PDF if you want.
