Magloop feature -requires $1.99 fee -yet almost nil capability
Whilst the App required $1.99 fee to go “PRO”. The magloop feature which required the PRO fee is so basic as to be practically useless. This feature really only suggests a wide min/max range for outer (Main) loop. Period. Nothing else! Nothing on Gamma matching, nothing on calculating Z, wavelength, capacitance, or even anything about the simpler inner (driver) loop sizing etc. Be aware that anyone who comes for this App specifically regarding designing magloops - There is very little here for you at the moment. I’m hoping the author(s) will see this and consider adding more capabilities. Seem a shame not to. I’m leaving 2-Stars because I see other features in the app but have not yet tried to use them.

Request Payment again
I paid the $1.99 for the pro and it keeps asking me to pay again. It won’t let me choose restore.
