The version of the Coil32 software, designed to work on mobile devices - smartphones and tablets running on the operating system Android. It works in versions of Android 5 and higher. Implemented calculation of the four types of coils:

• Single layer close-winding air core solenoid
  As the initial parameters you can choose two options:
  1. The former diameter and the wire diameter are known, the length of the winding is to be calculated.
  2. The former diameter and the winding length are known, the wire diameter is to be calculated.
• Single layer RF solenoid with winding pitch
• Single layer RF solenoid winding with rectangular cross-section wire
  
• Single layer RF solenoid with pitch, but non-circular winding
• Multi-layer air core inductor
• Multi-layer air core inductor with insulating pads
• Multi-layer air core inductor on a rectangular coil-former
  
• Multi-layer foil-wound coil
  
• Coil or choke on a ferrite ring (only for low-current RF circuits)
• The planar PCB coil
• Tesla flat spiral coil
• The software has additional modules that allow to calculate:
  • flat PCB coil with the meander form of turns;
  • search coil for a metal detector;
  • a single triangle, rectangle or round loop coil;
  • air core toroid coil with round & rectangular cross-section;
    
  • estimate influence of the shield on the value of coil inductance;
  • ferrite rod core inductor;
  • coil or choke in the pot core (ferrite or powder iron);
  • coil on the ferrite E-core;
  • coil on the ferrite U-core;
  • coil on the ferrite RM-core;
  • finding unknown permeability of a ferrite ring;
  • recalculate any coil with ferrite or iron core by determining its A_L factor;
  • Amidon™ cores - iron powdered & ferrite toroids, Pot-shaped , E-shaped & multi-aperture ferrite cores;
  • An optimal multilayer coil for the audio system filter (crossover);
  • A ferrite toroid inductor at the radio frequencies with Q-factor & self-capacitance calculations;
    
  • Bandspread capacitors calculation;

The functionality of all calculations is identical to the Coil64 version of the program. Possible differences in the results are due to the features of the Java-platform, which is the basis of Android-applications. In the calculation of an air core, the single-layer coil is now calculated all the parameters as in Windows-version of the software, including the quality factor and self-capacitance of the coil. If you need to calculate the close-winding single-layer coil, you need to set a winding pitch the same as the diameter of the wire with insulation.
The Android application is multilingual. Now available:

Added ability to select units including inches. The formulas and numerical calculation methods used by the program are described in detail in the help section of the site. The program requires permission to access the Internet to obtain context-sensitive help from this site. The app is adapted to phone & tablet devices both.
