Phase A — Validate on the web (timeboxed)
Use whichever AI web stack your team likes. Measure activation and retention signals, not likes on the prototype.
Phase B — Translate flows to mobile grammar
Mobile adds tab bars, stacks, modals, gestures. Rewrite the spec as screen bullets + navigation rules, then feed ShipNative. Reference PRD template prompts.
Phase C — Export and harden
Follow Expo EAS submission checklist before inviting beta testers through TestFlight.
