About this app

Simple calculator with its live browseable Java source code exposed in the background. Calculate and learn Java and Android programming. Or just use it...

Flaki - guts of apps.

Are You curious how things work? Do You open toys to see what's inside? Do You unscrew covers of everything you use to discover how it's made? Maybe You wear a watch with transparent dial for this hypnotic view of a clock mechanism at work... or just... you know... because it's cool (and somewhat geeky). This app is for You and is already unscrewed and open. Play and look at working Java source code, explore it, scroll, tap on some words.

Features:
- simple calculator (with memory!) in half transparent view;
- live Java source code in the background, shows executed lines, autoscrolls to hotspots;
- hide app view (menu option) to see the code on full screen;
- switch off autoscroll (menu option) and scroll it by yourself;
- double tap or pinch to change font size;
- tap on word to scroll to its definition in code or to go to its reference page on Android developers site.
