UI & UX Suggestions

Use a white bg, blue premium badge, gold stars, green verified checkmark colour palette to match the app's purpose. Keep the navigation simple — a bottom nav bar or a single-scroll layout works best for this type of app. Make sure every interaction provides haptic or visual feedback so the app feels responsive and polished.
