Essential application

I have used PDF Expert for almost 3 years and this app is the major reason I will stick with the iOS platform. It allows syncing of annotations and other changes across multiple devices using cloud storage. Supports multiple cloud services; I use Google Drive.

A significant feature is the ability to upload non-PDFs to your cloud storage, which are then synced to your phone or iPad, which you can then run using its "open with" functionality. Cant say enough good things. Readdle makes many good apps, but this is the best of the bunch
