Group trips abroad: currency conversion, who paid what, and settling up after — it always gets messy
WHY IT'S INTERESTING
Exchange rate locks at the moment you log it
Log a expense in JPY or THB and the app snapshots the exchange rate — so three weeks later the numbers don't shift. That's someone who's actually fought with a group expense spreadsheet after a trip

TECH GUESS
WeChat Mini Program (native or uni-app), likely Node/Python backend, AI-assisted frontend
