Hey Product Hunt! 👋 I built Kendali Duit after getting into an awkward situation with a friend over an informal loan. No one remembered the exact amount, no one wanted to bring it up again — classic. In Indonesia, informal lending is everywhere. Between friends, family, warung owners and their customers. But there's no good tool for it: spreadsheets are overkill, notes apps have no confirmation mechanism, and WhatsApp threads get buried. So I built something specific to how Indonesians actually operate: • Log a debt in 30 seconds • Tap once to send a WhatsApp reminder — message is already written • The payer opens a link to see details and confirm — no app download, no signup The payer never touches the app. That was the design constraint that made everything else fall into place. Would love your feedback — especially from anyone who's experienced the Indonesian "hutang" dynamic firsthand. 🙏
