This is an iPhone application that I developed for the first time.
For railway model layouts. 

This is an application that can calculate the horizontal and vertical lengths when laying out the railroad model tracks diagonally.
For example, when a straight track is laid out after laying a curved track(e.g. 45° angle).
Or straight tracks after laying out railroad points (e.g. 15°) etc.
If you lay out the track diagonally like this,
It is necessary to know the horizontal and vertical dimensions in order to combine other tracks to create a layout.
But, it is troublesome to calculate the size.
There is also need to rely on intuition.
So please, use this application.
This application you can easily calculate the dimensions of the track.

How to use
1. Enter a millimeter number for the track length.
Decimal point can be used.
2. Select an angle.

Calculation result
As the calculation result, the horizontal length (angle 0°), horizontal difference, and vertical length are displayed in units of 0.5 mm.
The error of the calculation result is less than 0.5mm

Reset button
The numbers and angles are reset.

Disclaimer of warranty
The calculation result is the numerical value which be calculated by the developer.
It may be different from the numerical value by model manufacturer.
In no event shall the developer be liable for any damages, cost, or loss of profits.
