Paisa
Personal finance tracker for India built on bank SMS, audited twice for accuracy
Python, SQLite, pandas
Overview
Paisa turns bank SMS alerts into a ledger that separates consumption from transfers, debt service and investments. Money is stored as integer paise, and every transaction points back to the message it came from.
Audits
Two audits checked the numbers, and every finding is closed apart from hand-labelling. The app runs locally, and a demo mode uses invented transactions.
