Follow the Money: Bill Tracker

Have you ever wondered where the dollar in your wallet has been — or where it'll end up next? Follow the Money turns every bill in your pocket into a little messenger.
Snap a photo of any US paper bill. The app reads the serial number, denomination, and series year automatically. Then it logs the bill with the date and your approximate location and shares it (anonymously) with everyone else using the app. The moment any other user photographs that same bill — across the city, across the country, years later — you get a notification. You see exactly where it went and how long it took to get there.
It's a real-time view of how cash moves through the economy, one bill at a time. Think of it as a treasure hunt that never ends.
KEY FEATURES

Smart Camera: Auto-detects the serial number, denomination, and series year of any US bill in seconds. No typing required.
Real-Time Cross-User Matching: Get a push notification the instant another user logs a bill you've previously logged.
Personal Bill History: Browse every bill you've ever logged, search by serial, and see the full travel history of each one.
Live Analytics: Community-wide stats — total bills tracked, unique bills in circulation, today's count, and a friendly leaderboard.
Map View: Watch your bills travel on a map as other users log them.
Privacy First: Your photos stay on your device. Only the bill metadata (denomination, serial, year, date, ZIP) is shared. Your name, email, and exact location are never shown to other users.

ABOUT THIS BETA
This is a brand-new app and we're building it in the open. Some features are still rough around the edges, and we love feedback — there's a "Send feedback" button in the About tab that goes straight to the developer. If something breaks or feels off, please tell us.
Follow the Money is an independent project. It is not affiliated with Where's George or any other currency-tracking service.
NOT A FINANCIAL APP
Follow the Money is not a banking, payment, or financial app. It does not move, hold, or transact money. It's a community-powered geography game built around the bills already in your wallet.
LEGAL HEADS-UP
The app does not endorse, recommend, or facilitate writing on, stamping, or otherwise defacing US currency. Please handle physical money in accordance with applicable law.
