Watch Rocket build
Rocket starts building immediately and shows inline progress in the chat. You will see it working through each file in real time, generating components, merging code, and writing logic.
Build progress on mobile
If generation fails, tap Retry. If it keeps failing, simplify your prompt and start a new build.
Specify the platform. Say “web app” or “mobile app” so Rocket does not need to ask.
Mention the purpose. “Build a booking system for a hair salon” gives Rocket more context than “build a booking app.”
Include key features. List the 3-5 most important features upfront. Rocket can add more later.
State your preferences. If you want dark mode, specific colors, or a particular layout style, say so in your first message.
Start lean, then iterate. Describe a focused core and add features through chat after the initial build. This produces cleaner results than asking for everything at once.
