Problem

People need simple, reliable tools for mental wellness on mobile — without a bloated experience or dependency on always-online services.

What we built

CalmDown is an own product built solo end-to-end with Jetpack Compose, Room, DataStore, WorkManager, AdMob, and Google Play Billing.

Key features

  • Modern Jetpack Compose UI
  • Offline-first local storage (Room + DataStore)
  • Background tasks with WorkManager
  • Monetization via AdMob & Play Billing
  • Full ownership of product and codebase

Result

A complete mental wellness product shipped as an independent own product — from architecture to store-ready monetization.
