I&#x27;ve tried Haxe, Racket, TCL&#x2F;tk, MOAI (Lua based), and others, but I am now using 8th, a Forth-like language that compiles to Android, iOS, Windows, OSX and Linux [1]. The only downside is that I still need a Mac to publish iOS apps. For Android, Windows and Linux, I am good to go. It uses the JUCE library for gui implementation. I have made two toy apps for Android so far, and I am still learning. It has a good library so far, but some people find Forth difficult. I find it concise, expressive and still readable after 6 months. The shortness makes code review a breeze.<p><pre><code>  [1] http:&#x2F;&#x2F;8th-dev.com&#x2F;</code></pre>
