Mobile Design Pattern Gallery: UI Patterns for Smartphone Apps (2nd edition) (repost)

When you’re under pressure to produce a well-designed, easy-to-navigate mobile app, there’s no time to reinvent the wheel—and no need to. This handy reference provides more than 90 mobile app design patterns, illustrated by 1,000 screenshots from current Android, iOS, and Windows Phone apps.

Much has changed since this book’s first edition. Mobile OSes have become increasingly different, driving their own design conventions and patterns, and many designers have embraced mobile-centric thinking. In this edition, user experience professional Theresa Neil walks product managers, designers, and developers through design patterns in 11 categories:
Navigation: get patterns for primary and secondary navigation
Forms: break industry-wide habits of bad form design
Tables: display only the most important information
Search, sort, and filter: make these functions easy to use
Tools: create the illusion of direct interaction
Charts: learn best practices for basic chart design
Tutorials & Invitations: invite users to get started and discover features
Social: help users connect and become part of the group
Feedback & Accordance: provide users with timely feedback
Help: integrate help pages into a smaller form factor
Anti-Patterns: what not to do when designing a mobile app
