13 years and thousands of users later, I rebuilt the whole thing from scratch. The original Objective-C app couldn't support what users were asking for (analytics, category budgets), so I moved to Flutter and rewrote every screen.

What's different: - Full redesign with a modern UI - Analytics: spending pace, month-over-month, day-of-week patterns, top expenses - Category targets: set limits per category, not just an overall budget - Category drill-down: see exactly where money goes within each category

What hasn't changed: - 100% offline. No account, no cloud, no bank connection, no tracking. - All data stays on the device. I literally cannot see your data. - Same daily budget concept — one number, color-coded feedback.

The hardest part was migrating existing users' Core Data (SQLite) to the new Drift database without losing any records. Existing users get the update automatically and see a migration flow that moves their entire history.

Happy to discuss the technical side (Flutter architecture, Core Data migration, App Store continuity with a full rewrite) or the product side.
