Kireilign, from SheepMedical (Japan), brings affordable clear-braces orthodontics to Taiwan. The KireiCare app extends this philosophy by handling the day-to-day hassles—progress tracking, wear time monitoring, braces replacement reminders, and clinic checkups all in one place.

The first challenge was mapping a complete user flow from signup through each feature. Five features created multiple user scenarios—some users update logs on time, others forget, and some skip steps entirely. Rather than branch each scenario separately, we designed one flexible screen that defaults to the ideal path but lets users manually adjust dates when needed.

Through testing and iteration, KireiCare became solid and scenario-proof. We built a backend CRM with an admin-friendly interface for easy management. Using React, Chakra UI, and PHP with SMS and LINE integrations, we created a technically accomplished web app that serves real patient needs.
