TickerTape

TickerTape is a premium, minimalist iOS currency converter. Its interface design is inspired by the nostalgic, industrial aesthetics of mechanical split-flap (Solari) boards traditionally found in classic European train stations and airports, transforming a daily utility into a unique visual and tactile experience.

Version 2.0.0 introduces a total redesign of the graphic interface and user interaction model, adopting an elegant look in warm dark tones with comprehensive native support for both Light and Dark Modes.

Main Features

1. Interactive Solari Split-Flap Board

• Realistic Physics and Sounds: The card segments flip with simulated 3D physics and trigger sequential mechanical clicking sounds as values change, faithfully recreating the feel of vintage flap boards.
• Industrial Grotesque Typography: Built using the DINAlternate-Bold typeface stretched vertically (.scaleEffect(y: 1.15)) for extreme legibility and a retro-industrial aesthetic.

2. Symmetrical Card Layout

• The digit card slots of all currency rows maintain a fixed, symmetrical width of exactly 10 slots.
• The currency symbol cards are displayed statically on the right side, left-aligned inside exactly 3 card slots.

3. Interactive Long Number Viewer (Hotfix v2.0.1)

• If a conversion value exceeds 10 digits, the 10th card displays a retro truncation indicator (>).
• A mint green info icon (i) will automatically appear next to the currency code.
• Tapping this icon triggers a haptic impact and presents a native alert containing the complete un-truncated number with all decimals, along with a direct action to copy it to the clipboard.

4. Dynamic Theme Engine (Light & Dark Modes)

• The application automatically adapts to your system theme, or allows manually selecting Light or Dark mode.
• In Light Mode, the Solari card flaps adopt a subtle off-white shade with dark charcoal text, creating a beautiful contrast on clean backgrounds.

5. Native iOS Gestures & Smooth Transition

• Migrated the listing mechanism to a native SwiftUI List container.
• Native support for dragging rows to reorder lists and swiping to delete items (swipe-to-delete).
• Card modules automatically hide with a scale and opacity animation when entering edit mode, ensuring rows never expand vertically or squeeze.

6. Smart Ad Placements & StoreKit Store

• Interleaved Ad Banner: The advertisement banner automatically anchors at position 6 (index 5) for lists with 5 or more items, and is completely hidden during edit mode to prevent any reordering layout interruptions.
• Dynamic Pricing: Fully integrated with StoreKit 2 to query Apple App Store servers and show dynamic, localized premium pricing in the user's account currency.

Architecture

TickerTape follows a clean MVVM pattern to ensure testability and separation of concerns.

• Views: (e.g., ContentView, CurrencyRowView) Handle layout and user input only.
• ViewModels: (e.g., CurrencyViewModel, StoreManager) Handle business logic, calculations, and state management.
• Services: (ApiService) Abstract the networking logic, handling errors and data merging.
