# CalcTrip

> The first app you open the moment you see a price abroad. FX · arithmetic · budget · place prices.

CalcTrip is a free, anonymous, offline-capable **travel super-calculator and
currency converter** — the one tool travelers keep open while abroad. It is a PWA
that installs to the home screen on iOS and Android, works offline, and needs no
login (an optional account only adds cross-device sync).

## Why travelers use it (benefits)
- **Know instantly what a price means in your own money.** Type any amount or
  arithmetic (e.g. "12,800 × 2") and see it convert live across your home and
  destination currencies — no separate currency app.
- **"Is this cheap or expensive here?"** Compare a price against crowd-sourced
  local price levels for the place/category, so you can judge value on the spot.
- **Stay on budget without effort.** See how much you've spent versus your trip
  budget, by category, while you calculate.
- **Zero-friction record-keeping.** Pressing "=" auto-saves the spend with the
  current location and time — no manual expense entry. Review or enrich it later.
- **Built for anyone, anywhere.** 10 languages, any currency,
  offline-first; your home currency is auto-detected from your locale.
- **Private by design.** Local-first; usage/price data syncs anonymously to
  improve price info, and **personal photos never leave your device**.

## What it does (features)
- Multi-currency calculator: live exchange rates, manual override, offline fallback
- Switchable rate basis ("1 USD = 1,500 KRW" or the reverse)
- Trip budgets + automatic expense tracking by category, with reports and a timeline
- Crowd-sourced, anonymous place-level price data (the "price map") for local cost comparison
- Receipt / menu / food / selfie photo capture (stays on device, saved to your gallery)
- Per-item unit-price extraction (a "10,000 × 2" spend records 10,000 each, not 20,000)

## Who it's for
Leisure travelers, digital nomads, and business travelers — anyone converting
currency, comparing local prices, and managing a budget in a foreign country.
