It asks for 1 permission, none of them sensitive.

What's new in v8.2

Version 8.2 Some bugs was rectified. Added possibility to clear saved dataset. Version 8.1 Added calculation of multi-layer air core inductor with interlayer insulating pads. Some bugs in interface and run-time was fixed. Prevented hung at long calculation (black screen). Tracking input incorrect data.

Description

From the listing uploaded by “ravenclaw”.

Coil32 is inductance coil calculator, that allows to calculate single-layer and multi-layer air core inductors, ferrite core inductors and chokes, flat coils on PCB etc. Single-layer air core coils are calculated by R.Weaver's numerical method for helical winding. Calculation of multi-layer air core coils are based on Maxwell's formula for mutual inductance between two coaxial conducting filaments. Because of more exact complex numerical method some calculations may be long (few minutes). The app allows to calculate needed Number of turns for desired value of inductance, not versa. I hope this app could be useful for HAMs, Audiophiles and other radio enthusiasts who needs to make DIY inductors. I need for help from native speakers to translate this app in Indonesian, Portuguese etc. If you can give me the help, please email me.
