I am mainly looking for apps which help increasing productivity and not the ones like Calculator, Periodic Table etc. Apps which are good for taking notes, taking handwriting input.
There are many apps that have search over the names of the files but not all content in the files. It is very slow to test all apps such as iAnnotate, PDF Expert, Amazing PDF Expert and GoodReader. ...
I am looking for a note taking app with white text on a black background that works with iCloud. Apps for Mac and/or iOS will work. Any recommendation?
