I don't mix my self but I was looking around and found a mixing .apk in the stuff I dled the other day. It is called E-liquid calculatetor on the Android market . But I can't up load it until I change the extension to something other than .apk .
I was going to upload it here to get some input as to whether it was actually accurate . But I can't because .apk files are not allowed. There seems to be some discussion as to the accuracy of some of these mixing apps and Ithought that this would be the place to find out if there aany good .
