Ranked in these QuestionsQuestion Ranking
Pros
Pro Easy docsets download
Download docsets from CocoaDocs.org, RubyGems.org, Maven.org (Java and Scala), Packagist.org (PHP) and GoDoc.org.
Pro Supports docsets generated using Doxygen
Pro Great fast documentation lookup
Has a handy sublime plugin. Press CTRL-H and it jumps straight to the docs for that object.
Pro Integrates well with a good selection of apps
They provide very useful integration with apps that are very fitting with using Dash's features. Once integrated, you can really get the feel for being a must have part of the app its integrating with.
Pro Great utility app to use for snippets
Snippet apps come in various forms, such as basic snippet (text) containers and added features with text / keyboard utilities to name a couple. This app not only includes this feature, but takes it a bit further than most by adding unique ways to further customize this practice to your own preference.
Pro Easy to create new docsets in case there isn't one that exits already
Gives plenty of guides and information on how to generate a docset.
Pro Free and open source
Source code is available on Github.
Pro Supports a lot of languages
C, C++, C#, CSS, HTML, Java, JavaScript, Lua, LaTex, Python, Ruby, SQL and more.
Pro Easy to setup
Codeit is really quick to load and pretty simple in terms of UI, so setup is a minute max. It's a web app, so it weighs nothing on your phone too.
Pro Live view
If you're editing a site and want to see how it looks, you can swipe up from the bottom edge and see it live, without any hosting, you can share these previews as well.
Pro Consistency
Codeit is available on Windows and macOS/iOS as well as Linux and Android, and looks the same on all platforms. The editor is pretty simple and you don't have to get used to new code editors every time you swap platforms.
Pro Supports 200 languages
Cons
Con Forced wait time to view docs
If you use the free version you are very often forced to wait 10 seconds to view something you've chosen to look at. If you change apps or lose focus of Dash, it'll start that 10 second timer over again. A real crappy thing to do to your users in order to get them to buy it. Forcing you to waste your time.
Con No multiple accounts
It would be useful to add more than one Git host account to Codeit.
