RimaKit is a sleek and minimal Kotlin Multiplatform UI library built with JetBrains Compose Multiplatform.
It includes handcrafted UI components designed for delightful cross-platform experiences — from swipeable Tinder-style cards to animated number flows and custom tab bars.

• Swipeable cards with smooth animations
• Animated number transitions
• Custom tab systems with icons
• Toggle switches with personality
• Clean design, fully composable and customizable

Make sure your project is set up for Compose Multiplatform (Android, iOS, Desktop).

Gradle/TOML integration coming soon.
In the meantime, copy components directly into your shared commonMain module.
