Suggested price plan for voltbuilder

Hi,my suggestion.1,one time half a year plan. 2,one time one year plan.3, plan as long as’ appstudio plan’
have not expired. Be it calculated based one appstudio ide one time or appstudio ide subscription. As I can only afford occasional purchase if appstudio. I am budget consuse as the budge of my revenue goes to medication expenses. At the moment, I have no plan to purchase voltbuilder subscription as I am afraid I might exceed my tight budget. Kind rdgs,tst
