Hey Product Hunt! 👋 During a trip to Japan, I wanted to keep track of my travel expenses, so I downloaded a popular budgeting app. But when I tried to use it, I realized I couldn't track transactions in two currencies at the same time — my home currency and Japanese Yen. On top of that, the only way to log an expense was to open the app and tap everything in manually. Super inconvenient. What made it worse: I was traveling with a group, and everyone was tracking their own spending separately. That meant we had to go through the tedious process of settling up after we got home. That's when it hit me — I have the skills to build something better myself. So I did. And that's how Penvo was born. It lets you do three things that app couldn't: 1. Record expenses via Apple Watch — just raise your wrist, say "lunch ¥1,200," and it's logged. When you mention a currency, the app records in that currency 2. Track multiple currencies in one trip — USD, EUR, JPY, CNY, all auto-converted 3. Share a ledger with travel buddies — they don't need a Pro account, just join via a link and everyone's expenses show up in real time. Would love to hear your feedback. Happy to answer any questions!
