PDFS
It is not a PDF-friendly world anymore. PDFs or PDF-derivatives such as flipbooks lack the accessibility, interactivity and social sharing that audiences now expect.
Disadvantages : • Multiple steps to access
• Expensive and time consuming to make 
• Multiple apps required in order to work on different devices • Not available on desktop
Disadvantages : • Poor user experience • Not easily readable across devices • Limited interactivity • Limited analytics
NATIVE APPS
Native apps need multiple steps to access, are expensive and time consuming to make and are not available on desktops.
