Minimalist Currency Converter for iOS
Michael Chumak
Overview
Managing multiple currencies daily requires speed, clarity, and precision. This case study showcases a modern iOS currency converter designed to eliminate interface clutter, speed up math inputs, and offer full UI personalization for daily power users.
Main converter screen with built-in theme and typography personalization controls.
Design Concept & Personalization
The primary focus of this concept was creating a human-centric interface that adapts to the user's visual preferences.
Custom Aesthetics: Users can switch between system, light, and dark modes, as well as select custom accent color themes.
Accessibility: Built-in controls for font scaling and bold text toggles ensure maximum readability for all user groups.
All-in-One Home Screen: Quick access to calculation inputs, active currency pairs, and instant settings.
Close-up view of the custom numeric keypad designed for rapid calculation inputs.
Fast Calculator & Custom Numpad UX
Standard iOS keyboards can feel cumbersome for rapid financial inputs. We developed a custom, high-contrast numeric keypad directly within the primary conversion screen.
Zero-friction inputs: Dedicated arithmetic keys (
+, -, ×, ÷) allow users to perform multi-step math directly inside the converter.Real-Time Exchange Rates: Live conversion feedback updates instantly across all pinned currency cards as the user types.
Currency list view, search by asset categories, and real-time exchange rate sync status.
Multi-Currency & Asset Management
Beyond traditional fiat currencies, modern users manage diverse assets. The app features an intuitive search flow organized by categories:
Comprehensive Asset Search: Quick filtering for global fiat currencies, precious metals, and cryptocurrencies.
Alphabetical Index Scroll: Fast jump-to-letter side navigation for smooth browsing through hundreds of currencies.
Live Rate Syncing: Clear status badges showing the exact timestamp of the last rate update.
