👋 Hi Product Hunt! I built CalcTrip out of a problem I hit on every trip: I'd see a price on a menu or in a shop and have no real feel for what it meant in my own money — and worse, no idea whether it was a fair price or a tourist markup. So CalcTrip is the one tool I now keep open the whole trip: - 💱 Type any amount or even arithmetic ("12,800 × 2") and it converts live between your home and destination currency — no separate currency app. - 🧭 "Is this cheap or expensive here?" — compare a price against crowd-sourced local price levels for that place & category, so you can judge value on the spot. - 🧾 Never lose what you typed — every calculation and payment you punch in on the go is saved to a history with its location and time. Those numbers you tapped in a hurry at a market stall, a taxi, or a restaurant don't vanish: back at the hotel or after the trip you can scroll the history, see exactly where and when each one happened, and tidy them up — no more squinting at receipts trying to remember "wait, what did I actually spend on that?" - 📊 Stay on budget without effort — pressing "=" auto-saves the spend, so your trip budget updates itself by category. No manual expense entry, no spreadsheet at the end of the day. - 📴 Works fully offline (bundled rate snapshot), installs to your home screen (PWA), needs no login, and speaks 10 languages. - 🔒 Private by design — your photos never leave your device. It's completely free and usable without an account. I'd love your honest feedback: what would make this your default travel calculator? And which city's local-price data should we deepen next? 🙏
