Questions & Answers

As answered by people managing StackMail and Catatku.

What makes your product unique?

Catatku's answer:

  • Runs without internet. Sync is optional, not required.
  • You pay once. Premium covers one year, Pro is permanent. Nothing auto-renews.
  • Separate books for personal, household and business money. Each book keeps its own accounts, budgets, reports, currency and month-start date (Pro).
  • Log a transaction by sending a WhatsApp message, voice note or photo of a receipt. This is a paid Pro add-on, sold in Indonesia and Malaysia.
  • No ads on any plan.

Which are the primary technologies used for building your product?

Catatku's answer:

  • Flutter and Dart, for Android and iOS.
  • SQLite for local storage on the device.
  • Supabase for optional cloud sync and backup.

Why should a person choose your product over its competitors?

Catatku's answer:

  • No subscription. Premium is one payment for a year, Pro is one payment forever.
  • The app keeps working on a bad connection or none at all.
  • Month-start date is set per book, so budgets and reports follow payday instead of the 1st.
  • Free covers unlimited transactions and stays free.
  • No ads, whatever you paid.

How would you describe the primary audience of your product?

Catatku's answer:

  • People tracking daily spending.
  • Couples and households sharing one budget.
  • Small businesses and freelancers who need business and personal money in separate books.
  • Main markets are Indonesia and Malaysia. The app is available in Indonesian, English and Malay.

What's the story behind your product?

Catatku's answer:

  • Indra Rahmana Hedar, a full-stack developer with over nine years in web and mobile, built Catatku in 2025 as a tool to track his own personal and business money.
  • It became a product under PT Tokokoding Ilmu Digital, based in Makassar, Indonesia.
  • The idea came from watching people quit expense tracking. They stop because the tools are tedious, not because they stop caring. So recording had to take seconds, and the reports had to build themselves.
  • The rules it was built on have not changed: your data stays on your device, the app runs offline, there are no ads, and upgrades are paid once instead of renewing forever.
  • As of August 2026 it has over 25,000 registered accounts and more than 260,000 recorded transactions.

Who are some of the biggest customers of your product?

Catatku's answer:

  • Personal. A main book for daily spending, recurring bills and personal savings in separate wallets.
  • Couples and households. Both people track one household budget from their own devices and see the same data.
  • Small business. Business money stays apart from personal money, with income, expenses, supplier debts and customer receivables all visible.
  • Freelance and side hustle. Project earnings and work costs stay separate from day-to-day spending.
