# iFarted > Send a friend exactly one thing: **"I farted."** A dead-simple cross-platform mobile app: pick a person, optionally attach your location, and send them a push notification that says exactly one thing — **"I farted."** They can one-tap fart right back. No typing, no inbox, no feed. Modeled on the 2014 **Yo!** app (context-based messaging) — with monetization in from day one. ## What it is - **iOS + Android** — React Native + Expo + TypeScript, one codebase - The fixed message is *"I farted."* — meaning comes from context (who, when, where) - Optional **location** attached per message → recipient sees a map pin - Custom notification sound; notifications are ephemeral by design (no history) ## Find & add friends (all three ways) - Unique **@username** + search - Opt-in **phone contacts** matching - **Invite code + deep link** ## Architecture | Piece | Stack | |---|---| | `apps/mobile` | Expo (React Native + TypeScript) client | | `apps/server` | Lightweight **Bun** relay → **Expo Push API** → APNs/FCM; SQLite storage (Node-runnable) | | `packages/contracts` | Shared API types | ## Monetization - Free tier with ads (AdMob) - One-time **Remove Ads** IAP (non-consumable, restorable) ## Status Design locked, zero code.
