I redesigned the user interface for a mobile application called Koinoike. Koinoike serves as a koi caring assistant, providing owners with vital information about their pond status and guidance on feeding each koi fish.
Design System
01 Typography
The Poppins typeface enhances the koi pond management UI with its clean, geometric structure and excellent readability. Its modern yet friendly style complements the soft color palette, ensuring a smooth and intuitive user experience. The even stroke widths and rounded forms create a balanced, approachable feel, making fish care tracking effortless and visually engaging.

02 Color
This color palette balances warmth and tranquility. The bold E54F5A red adds energy, while soft coral (FDACAA) and peach (FFB17A) create a calming feel. Muted F6EDED keeps it clean, and fresh A9C568 green adds a natural touch, making the interface both inviting and functional.

03 Grid
The grid layout ensures consistency and clarity with a multi-column structure. 20px and 30px margins provide balanced spacing, enhancing readability and ease of navigation for a clean, user-friendly interface.
