Description
This is an engineering calculator, with equation solvers, interpolations, matrices, wolfram alpha, converter, complex numbers, custom functions, variables... and more in the future!
This is an application designed for engineers but can be used by anyone. Once you open the app you'll see a simple calculator with a swipe keyboard but there's much more behind.
NOTE: SWIPE THE KEYBOARD TO SEE ALL THE FEATURES
Landscape mode plays nicely with your tablet. Most of the features are just a tap away now.
This is a powerful application which has the following features:
 Equation Solver: You can solve almost any equation. It supports:
> Nonlinear equations: Any type of equation, such as: 5*x+sin(x^3+2)=8 (up to 10 equations and variables, you can see 2 equations solved in the screenshots)
> Linear equations: Like 2*x+3*y=8, 3*x+6*y=3 (up to 10)
> Polynomials: Up to grade 20 (complex and noncomplex solutions)
 Interpolation
> Simple: Perfect for thermodynamic tables with only one variable (for example Temperature)
> Double: 2 variables interpolation. See screenshots for a preview
 Curve fitting
> You can get the closest curve given a set of points. You can choose between: linear, parabola, 3degree polynomial, power, exponential, logarithmic or even create your own curve. The tool will calculate square R too.
 Matrices: Since version 1.3 you can use matrices. Matrices are made of complex and real numbers and contain most common operations. Functions and operators currently supported: +, , *, /, determinant, transpose, ^,.^,.*,./, ^1 (Inverse), get, set, eyes (Identity matrix), ones. You can sum a number to a matrix similarly to Matlab, power each element individually...
 Vectors: Complex/real vectors with dot and cross multiplication (besides the applicable methods found in matrices)
 Function editor: Create as many functions as you want and save them under different categories. Using custom functions is extremely easy and very helpful. You can describe the functions and variables. Furthermore, you can take a photo that may help you understand and use the function correctly. Functions can be used in the calculator as well as in the equation solver.
 2D function plotter (Still in beta)
 Converter: It's useful to have a converter inside the app. It's got 19 conversions: length, area, volume, angle, time, speed, acceleration, flow, mass, force, torque, energy, density, pressure, dynamic viscosity, kinematic viscosity, temperature and currency.
 Wolfram Alpha search: Just touch the search button
 Complex numbers: The calculator supports complex numbers in both rectangular and polar notation. Polar notation us useful for phasors in Circuit Analysis.
 Variables: Just save any number as a variable and use it later.
 Constants: 6, more in next updates.
 Radians/degrees
 Easier decimal notation: 1.000000 is 1, 99999999 is 9.999E7 (depending of the decimal precision)...
 And probably more features in the future!
Permissions explained:
 INTERNET: To browse WolframAlpha
 WRITE_EXTERNAL_STORAGE: To store custom function photos in the SD card if available
This application can be moved to the SD card so it only takes about 1.3MB of Internal Storage.

A superb calculator This is a superb calculator. It has all the math and graphing features of a first class calculator, and it also supports vectors and matrices. Userdefined functions and variables are also supported, and a very useful implementation of a history list enables one to reuse previous expressions and results. It has a 3 swipe panel UI that sometimes makes it cumbersome to enter data (especially arrays) but an undocumented feature (swiping the input panel upwards) brings up the native keyboard that makes data en

LyricsPlayer

LyricsPlayer is not a Music Player. This app displays the lyrics of the song you're listening to. Instead of having to download a new music player or browse in google for the lyrics, this app gets the current track and searches for the them automatically. When you open the app the lyrics just appear and are saved so the next time you don't have to download them again. You can browse your downloaded lyrics in "Saved lyrics".
When listening to a song you want to see the lyrics of just open this app and the lyrics will appear automatically. When changing a song a notification will appear for 30 seconds and if you click it you can also see the lyrics. (This is enabled by default so you can test it and can be disabled in Settings. It's useful if you often wanna check the lyrics).
You can also pick a song from your music library or type the song name.
The app has 5 different themes (blue, green, pink, holo and holo dark) so you can customize it a little!
By the way, if the lyrics of the song are wrong you can always change the source.
The app searches in (at the moment) 6 different websites for lyrics.
This app is intended to work with as many music players as possible. It works in:
 Google Music
 SonyEricsson / Sony Music Player
 Winamp (Needs to be fixed)
 HTC
 Miui
 Apollo
 PowerAmp
 Samsung
 UberMusic
 Cubed
It may work in (added but not tested yet):
 Rdio
 Amazon
 LastFM
This program is still in Beta, things I want to add/improve:
 Add support for more players
 Add more websites for lyrics (for french and german songs basically).
 Change the icon
 [DONE] Fix problem with tildes
 Bugs/improvements
 [DONE] Appear in the notification bar for ~30 seconds after changing the track (This could be disabled in Settings)
NOTE: This app needs to create a service that it's triggered when the song is changed. This service is only about 3MB of RAM (and the cpu usage is almost zero). The service only does work when the song changes and the only thing it does is saving the artist and track name.
Permissions explained:
App:
 INTERNET: To search for the lyrics
 RECEIVE_BOOT_COMPLETED: To be able to listen to new songs intents (it's a really small service)
Ads (Required by TapForTap):
 ACCESS_NETWORK_STATE: To know if there's internet
 ACCESS_WIFI_STATE: To know if you're on WiFi
 WRITE_EXTERNAL_STORAGE: To save thumbnails
 READ_PHONE_STATE: To know if there's connection
I'm trying a new platform called TapForTap where ads are "free" and used just as a way to share applications. Everytime somebody clicks in an ad in this app I get a point that will be used to display the LyricsPlayer ad in another app. You can disable them in settings but since they're not annoying (I've even disabled them on landscape mode to gain vertical space) you should leave them on.

You have the chance to play as a little expressionless ball in its adventure trough the world.
You will need to solve puzzles using different objects. Use portals to get teleported and play with the momentum to reach the farthest places! Kill those enemies for extra points and try to get all the stars! Some of them are challenging! Jump from platform to platform avoiding getting shot by turrets or using objects as shields. There are different ways to pass the levels, discover your own!
In this first chapter you will have the chance to play the first 10 levels and soon many more will come!
The game is designed both for phones and tablets with a different set of controllers and you can also play in tilting mode (should it be called Hard Mode?) if you feel adventurous.
If you like the game don't hesitate to review it and share it with friends as that will help me to create new levels and add new fun objects to the game. Feel free to post your suggestions and comments. The game has been tested and should be stable but if you encounter any problem please email me first before putting a bad review!

 Function editor: Create as many functions as you want and save them under different categories. Using custom functions is extremely easy and very helpful. You can describe the functions and variables. Furthermore, you can take a photo that may help you understand and use the function correctly. Functions can be used in the calculator as well as in the equation solver.
 Converter: It's useful to have a converter inside the app. It's got 19 conversions: length, area, volume, angle, time, speed, acceleration, flow, mass, force, torque, energy, density, pressure, dynamic viscosity, kinematic viscosity, temperature and currency.
 Wolfram Alpha search: Just touch the search button
 Complex numbers: The calculator supports complex numbers in both rectangular and polar notation. Polar notation us useful for phasors in Circuit Analysis.
 Variables: Just save any number as a variable and use it later.
 Constants: 6, more in next updates.
 Radians/degrees
 Easier decimal notation: 1.000000 is 1, 99999999 is 9.999E7 (depending of the decimal precision)...
 And probably more features in the future!
