The old dreamlauncher-ios app became a bloated, over-engineered solution that tried to do everything. The new DreamLauncherLite focuses on doing one thing exceptionally well: cross-platform screen time tracking.

Benefits:
// Multiple auth providers, complex state management
class AuthenticationService: ObservableObject {
@Published var authenticationState: AuthenticationState = .unauthenticated
@Published var currentUserId: String?
private let firebaseAuth: Auth
private let appleAuth: AppleAuthHandler
private let apiClient: APIClient
private let analytics: AnalyticsService
private let userPreferences: LocalStorage
// 300+ lines of code handling:
// - Apple Sign-In
// - Firebase Auth
// - Email/Password
// - Anonymous auth
// - Token refresh
// - Deep linking
// - Account deletion
// - Profile updates
// - Multiple auth flows
}
// Single auth provider, simple state
class AuthService: ObservableObject {
@Published var isAuthenticated = false
@Published var currentUser: User?
private let apiClient: APIClient
private let keychain = KeychainService()
// ~100 lines of code handling:
// - Apple Sign-In only
// - Token storage
// - Auto-refresh
}
Reduction: 66% less code
// 15+ Prisma models used by the app:
- User
- RawLocationData
- RawCoreMotionData
- RawSleepData
- RawWorkoutData
- RawHeartRateData
- UserActivity
- UserLocation
- UserFavoriteLocation
- TimeWithFriend
- UserScreenTime
- UserBeaconEncounter
- GeofenceEvent
- WeeklySummary
- AlphaStudent
// 2 Core Data entities:
- ScreenTimeEntry
- User

The old dreamlauncher-ios app was a cautionary tale of feature creep and scope bloat. By trying to do everything, it:
The new DreamLauncherLite app follows the Unix philosophy:
Do one thing and do it well.
By focusing solely on cross-platform screen time tracking, it:
The lesson: Sometimes less is more. Way more.
❌ Abandon dreamlauncher-ios completely
✅ Build DreamLauncherLite from scratch
✅ Maintain simplicity
Let’s build something simple, elegant, and actually useful.
