Andrew and Alexa Kaz released Ruler 2.0, a small and good innovation of the ruler concept: instead of make little markings mentally match an object, Ruler is just a matter of aligning a pointer: alas, the exact measure value instantly appears.

Ruler 2.0 has an introductory price of US$ 0.99, € 0.79, and comes as a free update for buyers of version one.

But, this time, just version 2 of version 1 it is not: Andrew and Alexa point out that Ruler 1 was, by their admission, ugly and they rewrote the app from scratch to make it truly better.

To celebrate the launch, Andrew and Alexa are giving away one 64GB iPod touch with Retina display, one 16GB iPod nano, one Apple TV, and one iPod shuffle, all fresh and new from the recent Apple event.
