Between starting the book in September of 2010, a lot of mobile pattern collections have emerged.

I actually disagree with the principles behind most of them. Not all, but many. I've talked about this in some presentations, so for the record:

• Screenshot focused.
• Few or no explanations.
• Interface focused, with few nods to interaction.
• Too focused on one OS. Mostly, iOS.
• Mostly, really, iPhone. Far too often mobile means handsets.
• One tier of organization, and no cross-referencing. If you don't get their method of organization or referencing, you may not understand what options are available.

Of course, you may disagree. The presence of these is another key reason I am not worried about having too many screenshots in my patterns. There are plenty of others that do this. Enjoy.

Codified Pattern Libraries

• Android Patterns - One of my favorites, each pattern is drawn, has a lot of explanations and describes the interaction, and there's a really snazzy organization to help you drill down to the options available for your design problem.

• Mobile Design Pattern Gallery - Also an O'Reilly author, Theresa Neil has published this supporting website with the patterns from the book. They are abstracted at the top level, then explained as screenshots.

Screenshot- & Review-Oriented Pattern Collections

• Mobile UI Patterns - Mari Sheibley's quite large, regularly updated, and somewhat organized collection.

• Lovely UI - A collection of mobile UI elements, tagged so all the similar items can be found.

• Mobile Patterns - Ryan Sims' collection of patterns, with the opportunity for you to contribute your own to the collection.

• Pttrns - By By Robin Raszka & Chemix, seems to be more focused on interfaces (screen design) than even the others.

• Tappgala: The best in mobile interface design Organized by verticals (e.g. Healthcare) and about the whole app experience, not individual screenshots. Curated but allows contribution. Heavy iOS representation, but not officially restricted to that.

• Make Better Apps German-language only site, with long reviews of entire applications, including many screenshots.

iOS-only Patterns

• iOS Inspires Me A selection of items, broken down by icons, apps, web, etc. Some notes, review and other minor information attached to each item.

• Well Placed Pixels With no organization at all I can see, includes iPhone and iPad only.

• Landing Pad - A showcase of beautiful iPad applications again as a Tumblr blog-like, organization-free list.

• iOS Design Inspiration Grouped by icon, iPhone, iPad, web, and other top categories. Supports user star ratings by category, but little else.

• Tapfancy Grouped by verticals, with multiple screenshots (use left/right arrows) for each application.

Web-only Patterns

• Mobile Awesome All screenshots, no obvious organization, web-only maybe. Has attached blog and some other resources.

• Refined Mobile Mobile web-oriented. Organized by categories, and by color schemes, so very useful when looking for interface screenshots to crib from.

• AppSites A showcase of beautiful iPhone, iPad & Mac app websites. No actual items collected past the grid view. Clicks go to the actual site.

Screenshots From Designing Mobile Interfaces

• Screenshots for Designing Mobile Interfaces - This is just a collection on Flickr, of all the screenshots (or often, photos) of the various devices I own. Not organized into a library, but if you were looking for an old device especially, it might be here. Enjoy.

Anti-Patterns & Worst Practices

What would our jobs be without making fun of others? But really, it's important to recognize bad solutions, and know why they are bad so we can all improve. Here's a couple places that collect bad mobile solutions.

• WTF Mobile Web also on twitter @WTFMobileWeb. This also explains real well the point of sharing antipatterns.

• We have a mobile site!

Discuss & Add

Please do not change content above this line, as it's a perfect match with the printed book. Everything else you want to add goes down here.

Examples

If you want to add examples (and we occasionally do also) add them here.

Make a new section

Just like this. If, for example, you want to argue about the differences between, say, Tidwell's Vertical Stack, and our general concept of the List, then add a section to discuss. If we're successful, we'll get to make a new edition and will take all these discussions into account.
