Are you tired of paying for each and every API separately? Are you annoyed waiting for updates of already available content? Just use JDoc Reader and simply import any Javadoc API you need. JDoc Reader is a tool to read API's, which have been create with the Javadoc Tool, like

- Apache Ant
- Apache Solr
- Hibernate
- Java SE
- Google Guice
- Google Gson
- Ext GWT
- ...

You can also import your own API's generated by yourself with Javadoc. Just compress your API as a ZIP file and synchronize it with iTunes File Sharing or use the "Open in…" dialog (e.g. in Mail) to open it with JDoc Reader. If an API is included within an SDK, you can also synchronize the complete SDK. JDoc Reader will extract the API automatically and clean up unnecessary parts.

Of course you can use JDoc Reader on you iPad and iPhone without any extra cost.
