Changing and growing your app

You refine your app by chatting in Studio. Each message either makes a change or answers a question.

• A small change ("make the header dark green", "add a contact section") costs 1 Build token.
• A bigger change (new section with several moving parts) costs 2 Build tokens.
• Asking a question or chatting about your app is free. You only spend Build tokens when Hamish changes your app.

Helpful things to know:

• Undo Changes appears on the latest reply that changed your app (under Files updated). It rolls your app back if a change went the wrong way, and Hamish ignores the undone attempts afterwards so they will not confuse later builds.
• If a build hits a snag, Hamish tries to fix it automatically before handing back to you.
• Each reply briefly shows its token cost (for example "-1 token" or "-3 tokens"), so you always know what you spent.
• If a reply was not useful, use the thumbs-down on it (tooltip: "Response not right? Tap to refund tokens"). Where appropriate this refunds the tokens, and your next try uses a more powerful model.

Tips for better results: make one clear change per message rather than a long list; describe the result you want, not the technical method; and if you come back to an app after a while, give Hamish a one-line reminder of what it is and where you got to.
