Qalta Category Slider Money Flip Toggle Expense Income Interaction

This interaction showcases a highly polished transaction entry screen. Sliding horizontally through the category selector smoothly transitions between colorful circular icons, updating the category label below with a subtle fade. Tapping the currency symbol triggers a playful 3D vertical flip animation that rolls through different currencies and dynamically calculates the converted value underneath. Tapping the transaction type pill at the top flips it between Expense (orange) and Income (green) with a satisfying color and text transition.
