iPad Usability Best Practices Checklist
Introduction
In 2010, the year the iPad launched, The Nielsen
Norman Group conducted a first usability study
reporting how real users actually used a broad
variety of iPad apps as well as websites accessed on
the iPad. In 2011, they did a second round, fine-
tuning their previous findings. The results are two
+100 pages reports containing their findings,
recommendations and screenshots.
This document synthesizes these recommendations
onto 5 pages for use as a quick reference or
checklist.
The full reports can be downloaded for free from
the Norman Nielsen Group website:
