What we built

Kotlin MultiplatformCompose MultiplatformFirebaseRevenueCatKtorKoin

Worlds lets people keep dated memory journals, either alone or in invite-only shared spaces with a partner, friends or family.

We built Worlds from one Kotlin codebase with Compose Multiplatform, so iOS and Android ship together. That covers the calendar view, real-time sync, image handling and the subscription paywall.

  • Invite-only shared Worlds where every member adds memories
  • Private solo Worlds for personal entries
  • Photos and the story behind them, saved to the day they happened
  • Calendar browsing and search for old memories
  • Premium plan with unlimited Worlds and custom covers
