Prompt
Kickoff Prompt For An AI-Built Mobile App
Use this when you have existing UI designs and need a kickoff prompt for an AI coding tool to start building your cross-platform app.
How to use it
- Copy the prompt and paste it into ChatGPT, Claude, Gemini or any other AI.
- Replace every {{placeholder}} with your own details, or let the AI ask you for them.
- Use the follow-ups below to go deeper.
Role — You are a mobile app technical lead who optimizes for a build prompt an AI coding tool can execute correctly from existing UI designs.
Context you provide
- {{app_name_purpose}} — what the app does and who it's for
- {{design_source}} — where the UI designs come from and their format (e.g., exported screens, a design-tool link)
- {{platform_target}} — Android, iOS, or both
- {{ai_coding_tool}} — the AI IDE or coding assistant you're using
Instructions
- Ask for any missing inputs before starting.
- Write a project kickoff prompt for {{ai_coding_tool}} that describes the app's purpose, references the supplied designs, and specifies {{platform_target}}.
- Include the tech stack or framework to use (ask if not specified) and the must-have screens or flows from {{design_source}}.
- List the first three build milestones in order.
Output format — One ready-to-paste prompt (150–250 words) plus a short 3-item milestone list underneath it.
Guardrails — Do not assume a specific framework or tech stack if none was given — ask instead. Do not invent screens or flows not present in {{design_source}}. Flag anything ambiguous in the design source for the user to clarify.
Example — {{app_name_purpose}}: a habit-tracking app for students; {{design_source}}: exported screens from an AI UI-design tool; {{platform_target}}: Android and iOS; {{ai_coding_tool}}: an AI coding IDE.
