Press the (i) button at any time to switch between the computation screen and the help screen for a given task.
Select desired task by tapping on the blue arrows or the text between them (selecting the text opens a dropdown menu).
Having selected a task you can press the EX button to set an example set of values into the displayed cells.
Use the (+/) button on the last line to change the sign of a currently edited cell value (edited cells are highlighted with a larger font in white color).
Within the first 2 tasks the program computes cell values (after pressing the GO button) at certain positions within the table which cannot be edited.
Use the CL button to clear the table and enter new values at any desired position (if necessary).
Several tasks display intermediate results when you press the GO button , the final result appears after hitting the button 2 or more times.

Pressing at a computed value (11.667 in the example above)
shows in a blue frame the factor + operator that led to the selected value
from the previous value one line higher (in this case "7 / 0.6 = 11.667" )
See help text of the "Rule of Proportion" task (sometimes called
"Rule of Three" when only three lines are used) by pressing the
(i) button inside the program.
Enter the system of equations as matrix (2 lines * 3 columns , 3*4 or 4*5)
and press GO for each step of the solution.
Enter the factors a,b and c of a given equation
of type
f(x) = a*x^{2} + b*x + c = 0
or
f(x) = a * (x + b)^{2} + c = 0
Switching tabs automatically converts the factors a,b and c
(possible if parameter a is not equal to 0)
Press the [GO] button to compute possible intersections of f(x) with the xaxis
or press the blue "...draw graph" buttton in the middle of the screen to display
the function graph of f(x) :
Pinching with 2 fingers  center should be the axis intersection (00)  allows to zoom in and out.
implemented in version 1.2:
Optional a set of f_{i}(x) curves (where a selectable variable  a,b or c  goes through the values
i=5 to 5 in steps of 1) can be displayed.
Selection of a variable for parametrization is done by moving the finger vertically over the
numeric field for the desired variable.
Closing the box that appears or selecting another variable deselects the first choice.
Enter the 3 components of each vector above the yellow printed symbol (o,u,v,o2,w)
and press GO
Enter values as requested on screen (several coordinate layouts and value combinations
can be set by pressing buttons in the midsection of the screen) and press GO
Entering the requested start values and pressing the GO button
displays the annuity table (if possible for the given values)
Pyramid and cube have been implemented since version 1.2 ; Cuboid is new in version 1.3 ; unit conversion new in 1.5 (coming soon)
Clicking at a letter of the triangle , pyramid or cube image in the middle or the variable list in the upper part of the screen
selects entry of that value.
2 values are required to compute the complete right triangle, 2 suitably selected values are necessary for the pyramid,
1 for the cube and 2 for the cuboid ; select associated S.I. unit by pressing the [unit] key several times.
Computation is started with the GO button with automatic conversion of all units to one suitable common unit
and symbolic printout of the steps that are necessary for the solution.
(display of 'area','surface' and 'volume' in version 1.5)
note: display of "sqrt(...)" means "square root of ..."  e,g sqrt(2) = 1.414...
and display of "NaN" = "not a number" shows that no solution is possible for the given value(s).
The images of pyramid, cube and cuboid can be rotated with one finger.
The cube can be changed to a cuboid (with the parameters a,b,d and e)
using a 2 finger 'pinch' operation.
The application counts your steps (and the calories burned) based on the movement of the iPhone or iPod Touch when you carry it (wristwatchstyle , at a belt , stabilized in a pocket or tied to your legs  latter position at your own risk of course). Acceleration values for the x and yaxis of the device and the computed velocity values (actual, average and maximum velocity) are displayed on a timeline. The length of your steps can be set individually as well as the combination of axistypes (x,y or both axis) that are used to determine the number of steps. The value of burned calories (the program takes into consideration the speed of your movement when computing the value for each 5 seconds time interval) is displayed on the bottom of the main screen above the toolbar. 

Values for calories and distance can be stored in a table together with the current date. Single day entries in that table can be combined to entries for individually chosen timeintervals (e.g. weeks,months or the duration of a holiday trip). 



Das Programm zählt Ihre Schritte (und dabei verbrannte Kalorien) basierend auf der Bewegung des iPhone oder iPod Touch , wenn man das Gerät am Armgelenk, Gürtel, in der Tasche oder am Bein trägt  letztere Trageposition natürlich auf eigenes Risiko. Beschleunigungswrte für die x und yAchse des Geräts und die berechneten Geschwindigkeitswerte (aktuelle, Durchschnitts und Maximalgeschwindigkeit) werden in einem Koordinatensystem graphisch dargestellt. Die Schrittlänge sowie die Kombination der Achsen (x,y oder beide Achsen), die für die Zählung der Schritte genutzt werden kann individuell eingestellt werden. Der Wert der verbrannten Kalorien (berechnet unter Beachtung der Bewegungsgeschwindigkeit) wird unten auf dem Hauptbildschirm (über der Werkzeugleiste) dargestellt. 

Die Werte für Kalorien und zurückgelegte km können zusammen mit dem aktuellen Datum in einer Tabelle abgespeichert werden. Einträge für einzelne Tage in der Tabelle können zu Einträgen eines individuell bestimmbaren Zeitintervalls (z.B. Wochen, Monate oder die Dauer eines Urlaubsausfluges) zusammengefasst werden.
