Helping out to the Wikimedia mobile efforts is simple and fun. Below you will see that no matter if you're a reader, editor, or developer... there are numerous ways to participate and make mobile more successful.

- Become a Wikimedia Beta tester and try out new features.
- Help us expand our currently set of tested browsers.
- Test the Wikimedia mobile projects in the languages you know and report any issues.
- Help translate the mobile user interface and apps by volunteering at translatewiki.
- Promote the Wikimedia Mobile Projects among your friends and Wikimedia fellows through Twitter, Facebook and other social networking tools.

Mobile development for the Wikimedia projects centers around two main focal points: Mobile Web & Apps. Mobile Web refers to any of the tools that are used to power m.wikipedia.org while Apps refer to the applications that are currently available on iOS and Android.
Key resources 
- MobileFrontend extension for MediaWiki (the code that powers Wikimedia's mobile sites)
- MobileFrontend API
- MediaWiki core API
Please use bug reports to track progress and make comments.
Mobile Web 
The main mobile browsing experience on all the Wikimedia projects is controlled by an extension named MobileFrontend. It's written in PHP and is currently responsible for all the device detection, rendering, and custom content delivered to mobile devices. It's currently in very active development as the main piece of WMF mobile infrastructure.
Some of our users prefer the simplicity of having an app on their smart phone to quickly access Wikipedia. To support these users we've developed both a native iOS app and a Android app using phonegap.

Third party Apps 
Identifying your App 
We recommend and encourage third party applications to properly ID themselves by setting a distinct user agent when sending requests. This allows us to identify your app traffic distinctly from anyone else in case any problems arise. To do this easily please set your UA consistent with your app. The supported format is
App name / App version
ex. 'WikipediaMobile' ~ 'Wikipedia Mobile/2.0'
Mobile companies 
Professional mobile developers can get involved individually in any of the tasks listed above, and here is more:
- If you maintain a mobile app using the Wikimedia content or API, you can make sure that it is listed and updated at the Catalog of Mobile Apps.
- If you maintain a mobile browser or a mobile platform, you can include Wikimedia web pages to your test rounds and we are looking forward to get your feedback and bug reports. You can also keep your information up to date in the Table of Browsers Supported and the Table of Languages Supported.
- Consider the contribution of developer resources to Wikimedia projects fitting in your roadmap. The Wikimedia Foundation can help your developers getting involved efficiently in the community work.
- Are your mobile customers happier thanks to the fantastic work of the Wikimedia community? Please consider a donation or becoming a Benefactor or the Wikimedia Foundation. Funds for specific projects fitting in our mobile strategy are welcome too.
