m-ARTp (aka Polyhedra 3D) is a mathematical tool to represent and manipulate polyhedrons using Conway notation. You can apply Conway transformations to a seed polyhedron chosen from Platonic solids, prisms, anti-prisms and pyramids. No mathematics knowledge is actually required to use the application.
m-ARTz (aka Z-functions) is a mathematical tool to represent complex functions (imaginary functions) on a 2D plane using a colored approach, resulting in fantastic and suggesting drawings. Heike, phase portrait, HSV, and uniform color schemes are supported. White-bars, contour density, and hue ranges allow for enhancing the drawings to achieve some quite artistic results.
Though the heavily use of mathematics, you don't actually need much knowledge to obtain great drawings. The application comes with a comprehensive set of functions you can customize such you never feel lost. Still, if you don't know where to start from, some of the best results are usually obtained applying the log and pow functions randomly...

Simple yet powerful
calculator for programmers
BaseCalc is a programmer's calculator with a clean and minimalist interface for iOS7. It supports direct input and output in bases 2, 10, 16, and special IPv4 format. On top of the classical 4 operations, you can execute common bitwise operations (AND, OR, XOR, NOR, ROTATE, SHIFT, ARITHMETIC SHIFT).
Preference settings allow selecting internal word size (8, 16, 32, or 64 bits), signed/unsigned operations, representation mode (padding, IPv4, ...).
the French revolution
Prairial is a calendar tool that converts between the standard calendar and the short-lived Revolution calendar that was adopted in France during the 1789 French revolution. Use as a reference, it can also be used in genealogy to convert dates between the 2 calendars.
The Windows version also includes a converter between the 24h time and the 10-based clock (day of 10 hours of 100 minutes of 100 seconds) that was introduced too by the French Revolution.
Cyclodraw is the tablet version of the spirograph/mandala geometrical drawing toy. It mostly produces mathematical curves technically known as hypotrochoids and epitrochoids, along with gears, ellipses and rectangles. Curves can be laid together to produce fantastic drawings. The application has been designed for creativity (especially children creativity) without any mathematical knowledge ever required.

for basketball games
Basketball buzzer, is a 5x7 LED countdown chronometer as we usually see around sport arenas, especially with basketball games. When it reaches zero, it plays a buzzer sound. Both the countdown time and the buzzer may be tuned through the options dialog.
A typical usage is basketball, where one touches the screen whenever the ball is in play or the referee whistles, and the player icon is pressed when the ball changes hand. Bbuzz also supports the 14 seconds rule where the countdown may be reset to 14 seconds if a foul is made within 14 seconds of the end of the 24 seconds.
with a strong French accent
Here's a talking four-operation calculator with a strong French accent. It's useful in itself as a calculator, as it offers the common operations found on small calculators (+, -, /, x, %, 1/x) along with a single memory register.
It is, however unique, when the voice option is turned on (default), as it also speaks, reading/spelling the computed values or describing the executed functions. It will speak to you in English or Italian, either one with a French accent, or it will speak in French--with a French accent of course.
And be sure to enable the "Oh la la" mode.
for the office and school
It says it all
A most useful application displaying Thank You. A good match to the classical Hello World application though this one tries to display the Thank You text in as big letters as possible.
Did you know it actually displays Merci on French devices and Grazie on Italian ones? Definitely the "must have" application in the category of the useless ones!
