## scientific calculator

NHN-1 is a free advanced engineering and scientific calculator with a transparent widget that has fractions and percentage:

•A resizeable widget with arithmetic, percentage button, and fractions.

•Expression (formula) based input.

•Fraction input and output with conversion to proper fraction, mixed fraction and decimal. Even the quadratic or cubic root functions, for instance, will return fractions when the answer can be written as a fraction.

•Full history with buttons that load old results, in case you need to start over from a previous point.

•Unlimited memory slots that can be named and are always displayed on screen.

•Multiple input fields except on small phones. This let's you do short side calculations without losing your place.

•Pre-packaged functions for quadratic equations as well as many geometric formulae.

•Buttons that store user defined functions that are created by binding an argument to a binary operator.

•Visualization of multivalued complex functions (roots, inverse trigonometric, logarithm)

•Visualization of quadratic and cubic functions

•Visualization of angles returned from inverse trigonometric functions.

•Complex numbers are very easy to work with, and all functions work with complex numbers where they are defined (inverse hyperbolic cosine, for instance).

•There is a fourth layout for small phones that is not shown in the screen shots.

•A unit conversion utility that lets you build arbitrary composite units. Conversion factors are written to the history, so you can bind the factor with multiplication to do the same conversion many times.

The layouts are designed to be ergonomic for each of four device sizes in portrait and landscape. Here are some examples of what we've done to make the calculator easy and speedy to work with:

•On small tablets in landscape, the keys are split so you can operate the calculator with two thumbs.

•On small phones, the numeric keypad is right under your thumb when holding the device with one hand.

•Square root, square, inverse and negation are all close to the numeric keypad.

•On small tablets, the long "NHN-1" button is a gesture recognizer that lets you scroll the six input fields with your left thumb. That way you don't have to let go of the device with your right hand to click an input field.

## Notes' Rainbow Free

Can you guess all the notes?

Test yourself with Notes' Rainbow, the new music game of BisMag dev. A small piano made up of two octaves

where you have to recognize the sequence of notes played.

Some lifes and some replay will help you climb the seven levels. Moreover, in the Test Piano there is a piano, not professional, but it will help you to train your ear in order to face better the game.

Finally a CheckPoint, obtained after the third level, usable only once, you will allow to restart from the fourth, once lost all lives; In the case you will reach the seventh and last, come back to sixth.

Have fun with Notes' Rainbow!

Wifi File Explorer

- This utility can connect Android phones with another smartphone or a PC without data cable. Once the app will be installed, users will reach a connection on FTP protocol. User can copy or eliminate files like a normal USB connection. The FTP connection is not complicated. You should insert the address returned from the app in the address bar of any Windows/MAC window, or any other Chrome, Internet Explorer, Firefox browser. To link two smartphones users can use a simple file manager like ES File Explorer, exploiting its features in order to interface each other through a FTP connection. Wifi File Explorer works with any FTP client i.e. FileZilla.

## Auto Reply/Block

This application allows you to automatically answer or block a call after receiving an incoming telephone call.

This is very useful when it is not possible to be distracted, to answer or block call.

Features description:

- Selective call answer or block:

-- answer or black all calls

-- answer or block calls from a list

-- answer or block calls from hidden number

- Notification for display application and quick access to the settings

A further feature of this application is the ability to add exceptions, function very useful when we need, for example, to answer or not answer all incoming calls except a few.

For example, if you select to block all incoming calls by adding the exceptions of a few numbers, the phone will block all incoming calls except those received from the numbers in the exception list.

The application provides the ability to add numbers to the lists in several ways:

- Directly from the contact list of our rubric

- Or manually: here being able to choose whether to enter the entire phone number or the first digits or middle digits or the last digits.

## Sliding Puzzle

The 15-puzzle (also called Gem Puzzle, Boss Puzzle, Game of Fifteen, Mystic Square and many others) is a sliding puzzle that consists of a frame of numbered square tiles in random order with one tile missing. The object of the puzzle is to place the tiles in order ,by making sliding moves that use the empty space.

The puzzle also exists in other sizes, particularly the smaller 8-puzzle. If the size is 3×3 tiles, the puzzle is called the 8-puzzle or 9-puzzle, and if 4×4 tiles, the puzzle is called the 15-puzzle or 16-puzzle named, respectively, for the number of tiles and the number of spaces.

Features:

## Inverse Matrix

This app allows the calculation of the inverse of square matrix. The app is simple and intuitive, just size the matrix and insert the values, the app will do the rest.

The application can calculate matrices up to 15x15. To avoid crashes derived from the hardware limitations of a smartphone.

When you enter a value in a matrix, you can use the following

Operations: * / - + ^

Functions:

sqrt(x) Calculates the square root of x

exp(x) Calculates e^x (e = Euler’s number)

ln(x) Calculates the natural logarithm (base e) of x

log(x) Calculates the logarithm (base 10) of x

sin(x) Calculates the sine of x

cos(x) Calculates the cosine of x

tan(x) Calculates the tangent of x

asin(x) Calculates the arcsine of x

acos(x) Calculates the arccosine of x

atan(x) Calculates the arctangent of x

The argument x can be a function. Example: log(sin(pi))

The argument x of the trigonometric functions is in radians

Costants:

pi 3.14159… Example: sin(2*pi)

e Euler number 2.71828… Example: 6e-5
