Currency Converter

Most currency tools only accept static numbers and force you to recalculate elsewhere when dealing with discounts or taxes. FlexiCalc seamlessly pairs real-time exchange rates with an editable calculation engine, allowing you to convert between global currencies, inspect rate trends, and type math formulas directly

Two-Way Instant Conversion

Convert between any currency pair with flexible inputs and quick controls:

  • Quick swap: Tap the center switch button to reverse the base and target currency directions in one tap
  • Calculate while converting: The custom keypad supports direct arithmetic formulas (such as 120*0.8+15), computing the final amount and converting it instantly without switching between apps
  • Timestamped rates: The top bar displays when rates were last updated, with pull-to-refresh support

Historical Trend Charts

Spot market movements and understand historical exchange rate fluctuations:

  • Multiple timeframes: Switch between 24-hour, 7-day, 1-month, 6-month, and 1-year smooth trend lines
  • Key statistical metrics: Review high, low, average rates, and overall percentage changes for your selected timeframe
  • Slide to inspect past rates: Touch and drag horizontally across the chart line to examine the exact exchange rate at any historical date, while your amount recalculates according to that past rate

Quick-Conversion Tables

A quick-reference denomination table sits directly beneath the chart:

  • Review standard amounts such as 1, 5, 10, 50, and 100 in both directions
  • Glance at everyday prices quickly when dining out, shopping, or budgeting abroad

Multi-Currency List

Track and convert across several countries simultaneously:

  • Simultaneous updates: Pin multiple currencies; entering an amount in any card updates every other currency in real time
  • Tap to focus: Tap any currency card to instantly designate it as your active base input
  • Card management: Long-press any card to copy the plain numeric value or safely delete it from your list

Offline Conversion & Currency Search

  • Global coverage: Over 170 supported currencies, searchable by currency code (e.g., USD, EUR, JPY) or country name
  • Reliable offline fallback: Continue calculating on flights or in areas with poor reception using the latest cached exchange rates
