Expert Currency
A private, intelligent currency converter built exclusively for the Apple ecosystem.
Expert Currency is a modern currency conversion app created by independent iOS developer Milad Fakhr, designed to make global currency, precious metal, and cryptocurrency conversion simple, fast, and accessible across Apple devices.
Supporting more than 200 currencies, precious metals, and leading cryptocurrencies, Expert Currency brings live and cached exchange rates, historical charts, widgets, Apple Watch conversion, iMessage integration, and accessibility features together in one focused experience.
From everyday travel and international purchases to financial reference, precious metal comparisons, and cryptocurrency conversion, every part of the app is designed around clarity, privacy, accessibility, and seamless integration with the Apple ecosystem.

Expert Currency is designed specifically for Apple devices, operating systems, and platform technologies.
The app provides dedicated experiences for:

More Than 200 Currencies
Expert Currency supports more than 200 currencies, allowing users to quickly convert between currencies from around the world.
The app can automatically suggest useful currency combinations based on the user's region while still allowing any supported currencies to be selected manually.
Exchange-rate information is regularly updated from public and established rate sources.
Users can easily:
- Convert between supported currencies
- Reverse currency pairs
- Enter custom amounts
- Compare exchange values
- View the date of the currently available rate
- Access previously downloaded rates when offline
- Quickly return to frequently used currency combinations
The experience is designed to make both everyday and international conversions fast and understandable.
Precious Metals
Expert Currency extends beyond traditional currencies with support for major precious metals.
Supported metals include:
- Gold
- Silver
- Platinum
- Palladium
Users can compare precious metals against supported currencies and other available assets within the same conversion experience.
This makes Expert Currency useful not only while travelling or shopping internationally, but also when following the value of globally traded precious metals.
Cryptocurrency Conversion
Expert Currency also supports major cryptocurrencies alongside traditional currencies and precious metals.
Supported digital assets include:
- Bitcoin
- Ethereum
- A selection of additional cryptocurrencies
Users can convert between supported cryptocurrencies and traditional currencies using the same streamlined interface.
By bringing currencies, metals, and cryptocurrencies together, Expert Currency provides a single place for quickly comparing different types of global value.
Historical Exchange Rate Charts
Expert Currency includes interactive historical charts designed to help users understand how exchange rates have changed over time.
Available chart periods range from short-term views to historical periods of up to five years.
Users can:
- Explore historical currency movements
- Switch between available time ranges
- Touch and hold the chart to inspect individual values
- View historical dates and corresponding rates
- Share chart information as an image
Charts are designed to remain clear and readable rather than overwhelming users with unnecessary financial complexity.
Offline Currency Conversion
Previously downloaded exchange-rate information remains available when an internet connection is unavailable.
Expert Currency stores supported rate information locally so users can continue performing conversions using the most recently available rates.
The app clearly communicates the date associated with available exchange-rate information, helping users understand whether they are viewing current or cached data.
This can be particularly useful while travelling, during flights, or in areas with unreliable connectivity.
Privacy First
Privacy is a core principle of Expert Currency.
The app does not require users to create an account and does not include advertising, behavioural tracking, or analytics designed to profile users.
Expert Currency does not collect personal user data for its own purposes.
Currency conversion, preferences, and supported app functionality are designed to remain private to the user.
When exchange-rate information is retrieved from external rate providers, those providers may receive technical information that is normally required to process an internet request.
Expert Currency itself does not use this information to build user profiles or track users across apps and services.
The result is a currency conversion experience built around simplicity, transparency, and user privacy.
Apple Watch
Expert Currency includes a dedicated Apple Watch experience for quick currency conversion directly from the wrist.
Users can enter an amount using an Apple Watch-optimized keypad and perform conversions without navigating through a full iPhone interface.
The Apple Watch experience is designed to remain useful even when the user's iPhone is not immediately nearby.
This makes it particularly convenient for:
- Travel
- Shopping
- Restaurants
- Airports
- International payments
- Quick everyday conversions
The watchOS interface focuses on immediate access to the information users are most likely to need while on the move.
iMessage
Expert Currency brings currency conversion directly into Messages through its iMessage experience.
Users can quickly perform a conversion while having a conversation and share the result without repeatedly switching between apps.
This can be useful when discussing:
- Travel expenses
- International purchases
- Shared costs
- Prices
- Payments
- Currency comparisons
The experience is designed to make currency information easier to access within everyday conversations.
Widgets
Expert Currency provides widgets that make frequently needed exchange-rate information available without requiring users to open the full app.
Widgets can provide convenient access to selected currency information directly from supported areas of the Apple interface.
They are designed around glanceable information, allowing users to check important exchange rates quickly throughout the day.
Accessibility
Accessibility is integrated throughout Expert Currency rather than treated as an optional feature.
Supported accessibility technologies and behaviours include:
- VoiceOver
- Voice Control
- Larger Text
- Dark Mode
- Reduce Motion
- Differentiate Without Colour
- Increase Contrast
- Accessible controls and navigation
- Accessible chart information
Historical charts are designed to work with accessibility technologies, including audio-based graph exploration where supported.
The goal is to make currency information understandable and usable across different visual, motor, and interaction needs.
Designed for a Global Audience
Expert Currency is designed for people who regularly interact with more than one currency.
Support for 25 languages helps make the experience accessible to users across different countries and regions.
Common use cases include:
- International travel
- Shopping abroad
- Online purchases
- International business
- Expense comparisons
- Currency reference
- Precious metal tracking
- Cryptocurrency comparison

- Everyday financial calculations
The interface remains intentionally focused so users can obtain the information they need quickly, regardless of how advanced their use case may be.
Native Apple Design
Expert Currency is designed with a strong focus on clarity, familiar interaction, and native Apple platform behaviour.
The interface combines:
- Clear visual hierarchy
- Familiar system controls
- Adaptive layouts
- Gesture-friendly interaction
- Native light and dark appearances
- Platform-specific navigation
- Accessible typography
- System-aware interface behaviours
Each supported platform receives an experience adapted to its own display and interaction model.
The design is intentionally restrained so that currencies, rates, charts, and conversions remain the primary focus.
Exchange Rate Transparency
Exchange rates displayed by Expert Currency are provided for informational and reference purposes.
Rates are obtained from supported public and external exchange-rate sources and may differ from the rates offered by banks, payment providers, credit card networks, cryptocurrency exchanges, precious metal dealers, or other financial institutions.
Where appropriate, Expert Currency displays the date associated with the available rate so users can understand when the information was last updated.
The app is not intended to provide financial, investment, trading, or professional financial advice.
Flexible Premium Access
Expert Currency offers optional premium access through the App Store.
Premium access expands supported functionality on iPhone and iPad while keeping the purchasing experience straightforward and integrated with Apple's App Store systems.
Eligible subscriptions also support Family Sharing, allowing supported premium access to be shared with family members through Apple's Family Sharing system.
The Apple Watch and iMessage experiences are designed to remain accessible as lightweight extensions of Expert Currency.
