Hi Product Hunt 👋

Costbook is an expense tracker first:

  • Add an expense in a few taps, or scan a receipt or PDF and let AI fill it in

  • Organize your spending into lists, from monthly bills to a holiday or a wedding, each with charts by category, person and payment method

  • Any currency, with totals in your home currency

  • iPhone, iPad, Apple Watch and widgets, light & dark, 34 languages

When costs are shared, invite friends to a list. They join for free, and Costbook shows who owes whom.

No bank login, no ads. Free to start; Costbook Plus adds sync, unlimited lists, PDF/CSV export and more, with a 7-day free trial.

What's the one thing your current expense app gets wrong? I'd love your feedback.
