Voltbuilder free plan

I have the free plan for VB. Does this mean I may make and upload at least 1 native android app (or revision thereto) per day so long as it is under 10mb? Is the upload size the same as the size of the apk?

With the Free plan, you can do 4 Android debug builds in a day. The size measured is the upload size, which loosely corresponds to the apk size.
