This application is a funny way for your children to practice calculating. Especially the mental arithmetic is supported.
"Calculation King" is a collection of different games for primary school children. In various games the arithmetic operations can be trained.
- Currently 5 different games for practicing the basic arithmetic operations (e. g. arithmetic triangle, calculation wall, computing house, etc.)
- Different difficulty levels (from very easy to difficult)
- Maximum value for calculating (e. g. level to 10, 20, 100, 1000)
- Arithmetic operations depending on the level of difficulty
- No advertising
- No external links
In arithmetic triangles a number is located in each corner of the triangle. At each side of the triangle the sum of its two numbers of the must be entered in the box.
In a computing wall each field contains the sum of the two numbers below it. Depending on the difficulty level, 3 or 4 basic stones are placed.
In a computing house the calculation rule is given in the roof. Then the number in the left or in the right hand side must be calculated.
In a computing circle the arithmetical operations are given in the circle segments. The results have to be calculated clockwise and must be entered in the box next to the circle segment.
The calculation flower contains a number in the flower stamp. Each petal contains an arithmetic operation that must be applied to that number. The result must be entered into the box next to the petal.

To use the strobe tuner, select the desired note and observe the pattern created when playing. Rotation indicates that the note is sharp (clockwise) or flat (anticlockwise). The faster the rotation, the more out-of-tune. This rotation is very precise and gives a much more accurate result when compared to ordinary electronic tuners. Each ring on the disc corresponds to a partial above the fundamental (the two inner rings are below the fundamental) and can be used to tune instruments with many partials.
* Note and octave selection
* A4 = 440Hz (adjustable in fractions of a Hz)
* Mask aperture size (to adjust the pattern clarity)
* Noise threshold (to block out background noise)
* Frequency Calibration (adjusts in 0.1c increments to a specific device or instrument)
* Auto-detect note
This strobe tuner is not like some others around that "emulate" a "strobe display". This tuner has an internal model of virtual wheels and flash lamps that actually perform the same process that a real strobe tuner would do.
This free app is ad supported, so internet access is required. An unlock key is available on the market to remove ads, enable colour picking, and enable selecting of temperament (e.g. Equal, Just, Kirnberger, Werckmeister, Young). The free version must also be installed. Get it at http://market.android.com/details?id=net.adamfoster.android.strobe.key
Please contact me at firstname.lastname@example.org if you have any questions or find any bugs.
Currently this will remove all ads and enable gestures and colour picker.
Please download the free Stroboscopic Tuner app first, and if you like it, purchase this application to remove all ads. You must have the free version installed.
Thank you for your support.
Currently includes Flute and Clarinet (Bohem only). More instruments to come. Please request your favourites and report bugs to email@example.com
How to use:
Press menu to change instruments.
Swipe up or down to change notes.
Swipe left or right to change fingering.
The drop-downs at the bottom of the screen can be used to change note types (single notes, trills, tremolos, etc) notes and fingerings.
Red marks are keys to press down, green marks are keys to trill.
Drag left and right in the title bar to see longer note descriptions if available.
By default, there is one juggler in portrait mode and two in landscape, but this can be customized if you prefer a certain layout.

* Custom juggler and background colors
* Bounce tricks
* Seamless pattern transitions
Plus features (in app purchase):
* 3, 4, 5, 6 and 7 ball patterns, all selectable
* Multiplex patterns
