Same 13 features (MVP-5 + 8 expansion): #### 1. Event Brief > *Why it matters:* Without an anchor, the rest of the app is a pile of tasks > with no shared definition of success. #### 2. Guest List With RSVP State > *Why it matters:* Most planning decisions depend on headcount, and headcount > is only useful when it includes real constraints. #### 3. Private Planning Checklist > *Why it matters:* The app must help users know what to do next, not just > store event data. #### 4. Deadline Timeline > *Why it matters:* Event stress comes from late decisions, not from lack of > task storage. #### 5. Budget Buckets > *Why it matters:* Money is one of the fastest ways casual plans become > stressful, and even rough visibility is valuable. #### 6. Household-Based Invitations #### 7. Shared Cost Tracker #### 8. Menu And Dietary Planner #### 9. Guest Communication Log #### 10. Run Of Show #### 11. Post-Event Wrap-Up #### 12. Venue / Vendor Contact Sheet *(added in Round 2)* #### 13. Responsibility Assignment *(added in Round 2)* Critique the spec under the new constraint. Be specific and decisive — no hedging. 1. **What becomes EASIER on Android-native** that wasn't possible (or was awkward) in the web version? Think: system-level integrations the OS gives us for free. 2. **What becomes HARDER or REMOVED**? What needs to be cut from the original web spec because it depends on a server / backend / sharing? 3. **What 2-3 NEW features** does Android-native make obvious that we should consider adding? (Things that leverage the phone, not just the screen.) 4. **MVP recheck**: with these new platform realities, do the original MVP-5 still feel right, or should one swap out for something Android brings? 5. **Risks specific to single-device on-device storage** that we need to mitigate even in V1 (data loss, phone change, etc.). Be honest — not exhaustive — just the 1-2 things V1 cannot ignore. Format as 5 numbered sections. Terse, opinionated. codex 1. **Easier On Android-Native** Android makes the app much better at personal operational planning. - **Calendar integration** becomes obvious. Deadlines, run-of-show items, RSVP follow-ups, vendor calls, and payment reminders can become device calendar events or local reminders. - **Contacts integration** makes guest entry dramatically easier. Import people from contacts instead of typing names, phones, emails, partners, and households manually. - **Phone / SMS / email handoff** improves guest and vendor workflows. Tap a guest to text, call, or email. Tap a vendor to navigate, call, or open their website. - **Notifications** are stronger than web. Deadline Timeline and Checklist can actually interrupt the user at the right time. - **Offline-first is native by default.** No loading states, auth, sync failures, or backend availability. This is a planning notebook that works anywhere. - **Camera / file attachment** is practical. Receipts, venue photos, contracts, seating sketches, menus, and quotes can be captured directly into the event. 2. **Harder Or Removed** Anything involving collaboration is either cut or becomes “local-only assisted sharing.” - **Shared planning is gone.** No multi-user event workspace, no live checklist updates, no shared budget, no shared responsibility assignment state. - **Household-Based Invitations lose actual invitation delivery/tracking** unless done through SMS/email handoff. The app can track households and message history, but it cannot know who opened, accepted, or replied unless the user records it. - **Shared Cost Tracker must be renamed or scoped down.** On-device only means it can track who paid what and what people owe, but not collect money, notify others, or keep shared balances in sync. - **Responsibility Assignment becomes private delegation tracking.** You can assign “Alex owns flowers,” but Alex will not see it unless the user texts/calls them. - **Guest Communication Log cannot be automatic in full.** Android permissions around SMS/call logs are restrictive. V1 should support manual notes plus explicit “send SMS/email” actions, not background scraping. - **No account, no web access, no cross-device continuity** unless export/backup is intentionally added. 3. **New Android-Native Features To Consider** - **Smart local reminders.** Deadline reminders, RSVP nudges, vendor follow-ups, payment due dates, and run-of-show alerts. This should be first-class, not a side feature. - **Contact-powered guest import.** Pick from Android Contacts, group into households, attach phone/email, and launch communication actions from each guest. - **Receipt and document capture.** Camera/photo/file attachment for receipts, vendor quotes, contracts, menus, inspiration photos, and venue notes. This directly improves Budget Buckets, Vendor Sheet, and Wrap-Up. 4. **MVP Recheck** The original MVP-5 are still mostly right, but the priority changes. Keep: 1. Event Brief 2. Guest List With RSVP State 3. Private Planning Checklist 4. Deadline Timeline 5. Budget Buckets But Android-native makes **Deadline Timeline + notifications** more important than it was in the web version. It should not be a passive timeline. It should become the app’s operating system: reminders, due dates, and “what needs attention now.” No MVP swap needed, but I would reshape the MVP: - **Guest List must include contact import.** - **Deadline Timeline must include local notifications/calendar export.** - **Budget Buckets should include receipt/photo attachment if cheap.** Do not promote Shared Cost Tracker, Responsibility Assignment, or Household Invitations into MVP unless the product is willing to stay explicitly single-user. 5. **Single-Device Storage Risks** - **Data loss is the V1 risk you cannot ignore.** Events are high-effort data: guests, budgets, vendors, notes, timelines. V1 needs at least local export, Android backup support, or a manual backup file. “Data lives only in app storage forever” is unacceptable. - **Phone change / reinstall will break trust.** If users cannot move an event to a new phone, the app feels disposable. V1 needs export/import even if there is no cloud sync. The hard line: on-device only is fine, but **on-device only without backup/export is not a serious event planning app**. 2026-04-27T11:16:57.402064Z ERROR codex_core::session: failed to record rollout items: thread 019dcea7-c083-7e50-abe3-fbe77422b657 not found tokens used 3,416 1. **Easier On Android-Native** Android makes the app much better at personal operational planning. - **Calendar integration** becomes obvious.
