A small price keeps HarmonyBudget yours.
Most free finance apps survive by selling your data or filling your screen with ads for credit cards. We picked a different path so we can stay focused on the one job you hired us for: helping your group stay on the same page about money.
Keeps the app running
Your subscription pays for the engineers, servers, and support that keep HarmonyBudget reliable for your whole group — year after year.
No ads, ever
No credit-card upsells, no "recommended" loans, no banner clutter. The app your group uses is the app you came for.
Your data isn't the product
We don't sell your financial data to advertisers, brokers, or anyone else. You pay us, so we work for you — not them.
$10 USD/month, or $80 USD/year. Less than one round of dinner — for a tool that keeps your whole group on the same page about money.
