What does the Ionic Creator free version offer?

Hi there,

I started exploring Ionic creator after someone suggested that I try this over PhoneGap for building my hybrid mobile app. I put in some UI components for a prototype and everything looks great when I realized that I am unable to write any actual code without moving to the paid version. My question is, what does the free version offer? Can I not make any service calls with just using the free version? Can I not build a fully working prototype with the free version?
