And that's not all.
No extra apps needed.
Debts, under control
Loans and credit cards with minimum payment, due day, and interest charges — so you always know exactly how much is owed and when.
Subscriptions that don't sneak up on you
Every subscription with its renewal date — monthly, yearly, or a custom interval like every 4 weeks — so none of them catches you off guard.
Trends, month over month
How spending by category moves over time, so patterns a single month can't show start to show up.
Three steps.
Three steps.
One clear picture.

Questions, answered.
Questions, answered.
Before they come up.
How much does it cost?
The Free plan is free forever, with generous limits on accounts, transactions, debts, and subscriptions. A Pro plan removes those limits — see pricing for details.
Is my financial data safe?
Sign-in is Google-only — no password to leak. Data is stored in a private database and never shared with third parties.
Does it connect to my bank?
No — every movement is logged by hand. That's on purpose: it keeps things simple and never requires bank access.
Does it work on mobile?
Yes, it's a web app that can be installed on the home screen from Chrome or Safari, and works just like a native app.
Can I change the currency?
Yes — USD, COP, EUR, GBP, and CAD are available from the profile.
Can I manage it with an AI assistant?
Yes — LESFin exposes an MCP server so any compatible AI assistant (Claude, and others) can read your accounts and log transactions for you in natural language. Connect it from Settings: Claude web and mobile connect with one click (sign in and approve access, no setup), and Claude Desktop/Code connect with an API key.
