Dash is an API Documentation Browser and Code Snippet Manager. Dash stores snippets of code and instantly searches offline documentation sets for almost any API you might use. You can even generate your own docsets or request docsets to be included.
Documentation Browser Features:
• 150+ offline documentation sets
• Download docsets from CocoaDocs.org, RubyGems.org, Maven.org (Java and Scala), Packagist.org (PHP) and GoDoc.org.
• Supports docsets generated using popular tools like Appledoc and Doxygen.
• Methods are conveniently shown in a special Table of Contents.
• Highlighted in-page search.
• Save bookmarks of your most used documentation pages.
• Create search profiles to easily switch between docsets.
• Easily search specific docsets by defining keyword filters (e.g. start your query with "python:" to search only the Python documentation).
• Integration plugins for: Xcode, Alfred, Quicksilver, LaunchBar, Coda, Espresso, PopClip, Sublime Text, Atom, Chocolat, Emacs, Vim, BBEdit, TextWrangler, TextMate, Eclipse, AppCode, Android Studio, IntelliJ Idea, RubyMine, WebStorm, PhpStorm, PyCharm, Terminal, AppleScript.
• Easily integrate with any other application using the "dash://" URL scheme or the "Look up in Dash" system service.
• Fuzzy search. Don't let misspells get in your way.
• Built for speed. Searching is almost instant.
Snippet Manager Features:
• Collect snippets of code that you reuse often.
• Sync by saving your library in Dropbox.
• Over 80 syntaxes for code highlighting.
• Variable Placeholders can be edited before pasting.
• Abbreviations are expanded wherever you type them.
Special Snippet Placeholders:
• @clipboard expands into the contents of the clipboard.
• @cursor repositions the cursor after expansion.

Comments and Reviews
super helpful when working with APIs
What options do you have? What is most useful?
So I bought Dash when it came out, and found it very useful. However a year later I discovered DevDocs, which for the past 2 years I've used exclusively and never needed to use Dash again. DevDocs works great, and even has a desktop client. I've also found DevDocs to be a lot more intuitive to use than Dash, which UX seems overly complex.
I just wanted to point out that DevDocs does not support proprietary documentation due to licensing constraints; such as Apple's documentation. Dash also does a pretty good job at centralizing documentations from many sources, giving a much larger library than what's available through DevDocs.
In addition to what lhunath said, DevDocs doesn't give you the context (e.g. module) when there are multiple search results, which means you have to click each result to find the correct one.
