Status, one of the 2 winners of the Blockchain Startup Contest 2016, is a mobile Ethereum browser / OS.
It's inspired by WeChat and similar messaging focused applications. The rationale behind that decision is that nowadays most time on mobile devices is spent with messaging, as is well explained in this blog post by founder Carl Bennetts or in this presentation held on devcon2.

The current Developer's Guide is focused on OSX, but I managed to build a working Android APK with this instructions.
The UI already looks quite slick and polished, performance feels good.
They seem to have a good sense for UX including wording (with fun not missing).

A wiki is being built.
Their Slack channel is very supportive.

Nightly builds (for iOS, a Testflight request can be made).

Technically, Status is quite a interesting project.
The code is open source, with the central piece being the status-react repository. Most of it is written in Clojure (more precisely, ClojureScript which compiles Clojure code to Javascript), the UI is implemented with React Native (Javascript framework producing native code).
Further used:
Re-Natal for bootstrapping.
Leiningen (lein command) is a *tool for working with Clojure projects).
figwheel enabled hot loading of code into the browser.
re-frame is a ClojureScript framework for building SPA Apps.
