Emberfit is a complete workout-tracking app written natively twice: Kotlin with Jetpack Compose and Material 3 for Android, SwiftUI with SwiftData for iOS 17+, sharing one design-token file, one exercise library and one set of sample plans. Includes onboarding, three sample plans (strength, HIIT, mobility), 77 exercises with original text and vector illustrations, a workout runner with timers and rest, history, hand-drawn progress charts, body metrics, streaks, achievements, local reminders, dark mode, kg/lb and CSV export. Honest status: the Android project builds and its 99 tests pass; the iOS project was not compiled in the Mammoth lab (no Xcode) and ships with XCTests.

Marketing images come from an HTML UI preview and Roborazzi renders.
