PROBLEM

Most baby tracking apps are cluttered, ad-supported and treat every tap like a data point. Parents wanted something quiet — a private place to log the day and keep the memories that will matter years from now.

SOLUTION

Arkeen is a mobile-first journal that combines fast logging (feeds, sleep, diapers) with a soft memory layer (photos, first words, milestones), packaged in a calm, editorial interface.

ARCHITECTURE
  • React Native app with an offline-first data layer
  • End-to-end encrypted memory sync across a family group
  • Local-first logging — the app is fully usable with no signal
  • Cloud backup with per-child export as PDF or archive
  • Zero third-party ads · zero tracking
