Ratings and reviews

Trash, dev is a rip off merchant making the user jump through a bunch of hoops to get basic function working After they pay.

could not read the packet I was able to install the certificate in developer mode but could not find how to do the next step

Doesn't work. App crashed upon opening it. After a restart, the app just continually crashed without opening. Ended up uninstalling.
