Hi @chris.akb 
(did you just set up a new account?)
If you can tell us a little more about the app that you’re trying to build we’ll be able to give you some more specific info, but in general you will want to do the following:
- Use functions as much as possible
- Reduce your block count by using generic blocks
- Use dynamic content, rather than static content to reduce the overall number of screens in your app
Just in relation to your question:
User on both the free and PRO tiers get the exact same app building experience. The differences between the two are explained in a little more detail on our pricing page.
