Real fantastic piece of Software

Paulo Cunha

Mendeley is just a fantastic software which helped me immensely in my academic life. It has saved me from a huge amount of work by helping organise books and article references, as well as its PDF files. The feature of automatic referencing in several international references standards do also help me being more productive and concentrate my energy in thinking and writing than in managing the chaos of files and folders in a file system of any computer. And there is the cloud availability, and free space in this cloud, and is a must have for academic life at any level.

Great app but needs better keyboard functionality


I use this app a lot, but one feature that needs to be added is some way to scroll down the page using a keyboard on iPad. There appears to only be the option to scroll down an entire page with both up/left and down/right arrows. It would be great if it could be changed to left/right being full page scroll and for down/up to scroll bit by bit down the page. Add this and it’s an easy five star app for me.

Needs Apple Pencil annotations and zoom out in landscape mode


The app really needs the ability to draw annotations with the Apple Pencil in addition to just highlighting. PDF Viewer and PDF Expert both have much better annotation features. Additionally, you need the ability to zoom out when in landscape mode. The PDF defaults to the width of the screen and that is too zoomed in to see a lot of the pdf you’re trying to work with.
