# Description

The application is essentially a presentation of code optimizations. The example used is a presentation of moving electrical particles in 2D space. Pure JAVA code is not always the best choice, for example, Super NEON code runs almost 100 times faster then Java code.

Five different types of code are implemented in the application:

- JAVA -> Pure java code

- Super JAVA -> Optimized java code

- C++ -> C++ code in native library

- NEON -> use NEON vector instructions in native library

- Super NEON -> use NEON vector instruction in assembly language in native library

In the menu bar you can run performance tests or get information about your phone's processor.

Excellent Really nice view of different programming skills

Fred Garvin

Does all that it says including the Perform"acne" Test (funny typo on the popup window...not that your app is funny, seems very useful...but that's gotta make you smile just a little? "Performacne Test", that just kills me...eh? (nudge nudge) )

Useful app to solve those electrostatic problems that many of us find when studying physic courses at school/college. With this app you will be able to know the electrostatic force between charges or among multiple of them, the electric field created by one (or more) point charge, the electrostatic potential, the energy between charges or the work needed to move a point charge. And all that for two or more point charges!

Besides, you will find the explanation of vectors that you may need to succeed in solving this type of problems and, of course, a detailed exposition of measure units, with its names and symbols, and powers of ten.

All you need to deal successfully with this interesting subject.

We would like to hear your opinions and suggestions to improve it!

If you are interested in having a calculator that covers all topics in physics and not only Electricity and Magnetism, Physics Formula Calculator is also available. It contains all of the formulas included in this app and formulas ranging from newtonian mechanics, waves and optics, fluid mechanics, thermal physics, and atomic and nuclear physics!

## Field Visualizer

This app allows you to measure and visualize the strengths of any magnetic or WiFi fields, within any rectangular region you chose, without the need for any special devices!

Field Visualizer allows you to "see" the otherwise invisible magnetic/WiFi fields by plotting the strengths at each point in space on a 3D mesh. This 3D mesh is overlaid on a real-time camera preview, which gives the user a near Augmented Reality experience.

Various 'Viewport' and 'Graphics' controls allow the user to tweak the rendered 3D mesh to their liking, and then align it with the measured region as seen by the camera. Save the final image and share it with your friends.

Detailed instructions on how to use the app are given in the app's "Help" page.

Tested on:

- Samsung Galaxy S4 (Android 4.2.2)

- Samsung Galaxy SII (Android 4.0.3)

- Asus Transformer Pad TF300T (Android 4.1.1)

- Samsung Galaxy Ace (Android 2.3.6)

Enjoy seeing the invisible! ;)
