Monarch Money Bridge

Monarch Money is great — but it doesn't natively support foreign banks or currencies. This bridges that gap: share a receipt image from your phone, and it OCRs it, converts the currency, and imports it directly into your Monarch account.

Quickly add transactions by hand — Amount, Currency, Date, Merchant — without needing a receipt photo.

📱

Native Share Sheet

Installed as a PWA, it appears in your phone's Share menu — share a receipt image directly from your camera roll.

Credentials encrypted at rest with Fernet. No logs of sensitive financial data. Runs locally on your own server.

🤖
