Sincere Inc. (Headquarters: Bunkyo-ku, Tokyo; President and CEO: Ken Nakamura) announced that its subsidiary, Karacon Works Co., Ltd., has launched an official smartphone app for its color contact lens e-commerce site, 'Mew contact', available on iOS and Android. ■ Background of App Development: From Web to a Personalized Experience 'Mew contact' has primarily operated as a website. To meet the needs of users in their 10s and 20s who want to catch trends quickly, and those in their 30s and 40s who want to efficiently repurchase items, we developed an official app to provide a "faster, more comfortable, and personalized" shopping experience than a browser. ■ Three New Experiences Offered by the App 1. Smooth Access to Ideal Lenses with Intuitive Operation: The app provides an intuitive interface to easily search for products from a wide lineup. 2. "Push Notification" Function: Delivers real-time updates on restocks of popular items and sales information, preventing missed opportunities. 3. No Need to Log in After the First Time: Once logged in, you can resume shopping anytime. This speeds up access to your favorites list and order history, making repeat purchases possible in just a few taps. ■ App Release Commemorative Campaign To celebrate the app's launch, we are giving points to all customers who either newly register or log in for the first time through the app. - New member registration: 500 points - First login for existing members: 300 points - Campaign Period: From May 14, 2026 (Thu) ~ End date TBD - Point Expiration: 3 months from the date of issue. ■■ About 'Mew contact' ■■ Launched in 2013, 'Mew contact' is a specialized e-commerce site for color contact lenses with the concept of "the cutest you ever, a new you," offering a wide range of products and trend information with a motto of "becoming cute safely and securely."
