HowMuchFx
Zero-typing visual currency cheat sheet for world travelers
I got tired of typing into calculator apps while traveling overseas, so I built HowMuchFx — a zero-typing currency cheat sheet that works 100% offline. Would love your feedback!
Hey Product Hunt community!
I'm super excited to share HowMuchFx with you all today!
Like many of you, whenever I travel abroad—standing in front of street food stalls in Bangkok or shopping in Don Quijote in Tokyo—I always found myself stressed out trying to do mental math or typing foreign prices into a clunky calculator app with a tiny virtual keyboard while holding bags with both hands.
So I decided to build **HowMuchFx (https://howmuchfx.app)** — a visual, zero-typing currency cheat sheet designed for real-world travel:
🚀 **Key Highlights:**
• **Zero-typing slider & steppers**: Adjust amounts with a simple thumb slide or tap `[-]`/`[+]` micro-steppers. No annoying virtual keyboards.
• **Instant 0.1s Bidirectional Swap (`⇄`)**: Flip between your home currency and local travel currency in a single tap.
• **100% Offline Ready (PWA)**: Works seamlessly in airplane mode, inside subways, or when roaming signal is spotty.
• **30+ Global Currencies**: Pin and reorder currencies to customize your own travel cheat sheet.
• **Zero ads, zero logins, completely free.**
I built this scratching my own itch as a solo developer, and I'd love to hear your thoughts and feedback!
👉 What currency pairs do you use most when traveling?
👉 Any features or travel tools you'd like to see next?
Thank you so much for your support, and happy travels! 🚀🎒
