Principal Plan is envelope-based budgeting software for Windows and Mac. Give every dollar a job when it arrives and see what's safe to spend before you spend it. It's a native desktop app, not a web app: it works offline, needs no account, and keeps your financial data on your own computer. Import bank files (CSV, OFX/QFX, QIF), reconcile statements, and use the optional iPhone and Android companion to check envelope balances on the go. Free 60-day trial.
