Honeycomb is a personal finance app I designed and built as a solo developer, from initial wireframes in Figma through to a published App Store release. The goal was to build something I would actually use; a privacy-focused budgeting app that keeps your financial data on your device, with no ads, no trackers, and no subscription.

Architecture
The app follows a layered architecture separating concerns across models, services, screens, and widgets:
lib/
├── models/ # Data representations for financial entities
├── services/ # Business logic and data management
│ ├── DatabaseHelper
│ ├── CloudKitBackupService
│ ├── AuthenticationService
│ ├── RecurringPaymentService
│ └── DebtPaymentService
├── screens/ # UI organized by feature
├── widgets/ # Reusable UI components
└── utils/ # Helper functions and formatters
Honeycomb is built with privacy as a core principle:
- All financial data is stored locally on your device
- iCloud backups go to your personal iCloud account only
- No analytics or data collection of any kind
- No ads or third-party trackers
