_Feral_

A consumer mobile product built around a behavior-mirror pet — a pixel creature that mirrors your real activity and roasts you, with AI-generated daily banter, when you slack.

/01 what we did

We designed and built Feral, a consumer mobile product built around a single sticky idea — a “behavior-mirror pet.” The user's Grem, a pixel creature, mirrors their real-world activity: it thrives when they stay active and turns feral when neglected, delivering AI-generated daily roasts in a savage, dark-humored banter style.

How it works

  • /Syncs steps, workouts, and sleep via HealthKit (iOS) and Health Connect (Android)
  • /The Grem's mood and state react to real activity in near real-time
  • /AI-generated daily roasts in a distinctive, dark-humored voice
  • /Reaction GIFs paired with each roast for personality and shareability
  • /Subscription monetization handled through RevenueCat

Tech stack

  • /Mobile: Expo React Native
  • /Backend & data: Supabase (Edge Functions · Deno/TypeScript)
  • /Health & device: HealthKit (iOS) · Health Connect (Android)
  • /Monetization: RevenueCat
