Adds groupDigits(), a display-only formatter that inserts the current locale's digit-grouping separators into an amount's integer part (e.g. "1,000,000.5" in en-US vs "1.000.000,5" in de-DE, where the roles of "," and "." are swapped, or hi-IN's irregular "12,34,567"). Delegates to each platform's native locale APIs (java.text.NumberFormat/DecimalFormatSymbols, NSNumberFormatter/NSLocale, Intl.NumberFormat with BigInt for arbitrary precision) rather than reimplementing grouping rules, and never touches the canonical '.'-decimal strings the rest of the app parses and stores. Applied via a Compose VisualTransformation (BTC/Sats/fiat/manual-rate fields, plus the read-only rate display) and, on the native SwiftUI screen, by re-deriving the field's displayed text on every change. Also made input parsing locale-aware: sanitizeDecimalInput now recognizes the locale's own decimal separator (e.g. what a locale-aware decimal keypad sends), not just "." — with a stricter rule on the SwiftUI side specifically, since its single text buffer re-feeds the grouped display back through sanitize, so a "." can be grouping noise there rather than a decimal point. The exceeds-max-supply warning's "21,000,000 BTC" is no longer baked into the localized string with hardcoded grouping; it's substituted in at runtime via groupDigits so the link-detection text always matches exactly, in every locale.

Supported Platforms
iOS 16.0+ • macOS 13.0+ • Android 10.0+
Kotlin Multiplatform
This is a Kotlin Multiplatform project targeting Android, iOS, Web, Desktop (JVM).
-
/iosApp contains an iOS application. Even if you’re sharing your UI with Compose Multiplatform, you need this entry point for your iOS app. This is also where you should add SwiftUI code for your project.
-
/shared is for code that will be shared across your Compose Multiplatform applications. It contains several subfolders:
- commonMain is for code that’s common for all targets.
- Other folders are for Kotlin code that will be compiled for only the platform indicated in the folder name. For example, if you want to use Apple’s CoreCrypto for the iOS part of your Kotlin app, the iosMain folder would be the right place for such calls. Similarly, if you want to edit the Desktop (JVM) specific part, the jvmMain folder is the appropriate location.
Running the apps
Use the run configurations provided by the run widget in your IDE's toolbar. You can also use these commands and options:
- Android app:
./gradlew :androidApp:assembleDebug - Desktop app:
- Hot reload:
./gradlew :desktopApp:hotRun --auto - Standard run:
./gradlew :desktopApp:run
- Hot reload:
- Web app:
- Wasm target (faster, modern browsers):
./gradlew :webApp:wasmJsBrowserDevelopmentRun - JS target (slower, supports older browsers):
./gradlew :webApp:jsBrowserDevelopmentRun
- Wasm target (faster, modern browsers):
- iOS app: open the /iosApp directory in Xcode and run it from there.
Running tests
Use the run button in your IDE's editor gutter, or run tests using Gradle tasks:
- Android tests:
./gradlew :shared:testAndroidHostTest - Desktop tests:
./gradlew :shared:jvmTest - Web tests:
- Wasm target:
./gradlew :shared:wasmJsTest - JS target:
./gradlew :shared:jsTest
- Wasm target:
- iOS tests:
./gradlew :shared:iosSimulatorArm64Test
