Hey Product Hunters, I built this App out of frustration with traditional personal finance apps. Most trackers demand that you navigate multi-level menus, categorize from dropdowns, and surrender your financial history to a cloud database—all just to log a $4 coffee. I wanted to test a core hypothesis: people log habits faster when data behaves like a physical toy rather than an accounting sheet. Here’s how the system works: Zero-friction logging: The category is the bubble. Tap the bubble, punch the digits, done. Whats best? Same time sync to a Google Sheets Physical metaphor: Spending magnitude is mapped directly to bubble area. A glance tells you where the money went without reading a single digit. Privacy first: There is no user database, no sign-in, and zero analytics tracking. Everything lives locally in SQLite. For backups, I built an optional Google Apps Script connector so you can beam transactions directly to your own private Google Sheet without a third-party server in the middle. I’d love to hear your thoughts on the physics feel, the glanceable canvas, and any features you'd like to see together with it.
