Finally, an app that calculates how many wraps of Kanthal or NiChrome are needed for whatever Ohm build you want! Simple and easy to use, you do not need to do any math. Simply fill in the blanks, and FireWrap does the rest.

FireWrap offers two modes: Total and Wraps.

Total: Enter the information, and FireWrap tells you the resistance of the build.

Wraps: Enter the information, including the desired build resistance (Target Resistance), and FireWrap tells you how many wraps of the chosen resistance wire you need to get the desired resistance.
