Sorry for the late reply. There is a manual in the latest version. The operation method is described in "? icon > help > manual". Also, I have released another app, "Rail Model Calc". The operability is similar to that of a normal calculator. It has a more intuitive operability and can also calculate Curve and S-Curve, so please try installing it.
Rail Model Track Calc helps you calculate the horizontal and vertical lengths needed when laying out railroad model tracks diagonally. You input the track length and angle, and it provides the precise dimensions for your layout.
The calculation results are displayed in units of 0.5 mm, with an error margin of less than 0.5mm. This ensures a high degree of precision for your model railroad track planning.
This calculator is for the railroad modeling hobby. While it provides calculated values, the developer notes that commercially available railroad model rails may have dimensional errors, and results may differ from manufacturer specifications.
