Hi Product Hunt 👋 I'm Huu, a front-end developer from Ho Chi Minh City. I built DIW solo — React Native app, Node backend, everything. The idea came from a trip with friends. Someone paid for dinner, someone else for the hotel, and by day three nobody could remember who owed what. I tried the existing apps, but they all hit the same wall: everyone in the group has to download the app and create an account. In a group of eight, two people do it and the rest go back to screenshots in the chat. So DIW works the other way around. Only the person tracking the expenses needs the app. You create a group, log the expense, pick the split, then send a link. Your friends open it in any browser and see exactly what they owe — no app, no account, nothing to sign up for. It's live on iOS and Android, fully localized in Vietnamese and English. Still early, so I'd love feedback on the split flow especially — that's the part I've rewritten the most.
