Claude for iOS app with AI

Plan a small, well-scoped iOS app for the idea below. Don't write Swift code yet.

Idea:
"""
{{1-line product description}}
"""

Constraints:
- Solo developer, weekend MVP, then iterate.
- Native iOS only (SwiftUI). No cross-platform unless I push back.
- Local-only data unless I ask for sync (privacy + review speed).
- No 3rd-party SDKs that block App Store review (no obscure analytics, no SDKs that violate ATT).

Output, in this order:
1. **Screens** (3 to 6 max for MVP) — name + 1-line purpose.
2. **Data model** — Swift types or SwiftData / Core Data schema, whichever is simpler.
3. **Permissions / capabilities** — exactly what entitlements you need and the App Store review reasons.
4. **App Store hooks** — name candidates (3), category, the 1-line subtitle, the "what's the screenshot story".
5. **Out of scope for v1** — 3 to 5 features I should NOT build before launch.

Push back if the idea has obvious App Store rejection risks.
