Six offline apps for keeping your own money straight: a zero-based budget, a debt payoff plan, invoices, chasing who owes you, billable hours, and splitting costs with friends.
No account and no subscription. Each app is a single file that runs in your browser on Windows or Mac, offline. Your data stays on your computer.
Who it's for: Freelancers, side hustlers and anyone who wants their budget and invoices on their own computer instead of in another subscription.
