Theory’s Official App has recently been updated with the addition of a membership program, making shopping more convenient both in-store and online. Established in 1997 in New York, Theory is a contemporary brand for women that offers comfortable, stretchy materials with a focus on simplicity and subtle trends, while constantly proposing new fashion ideas.

The app offers several features, including the MEMBERSHIP program, which allows easy access to a barcode via the “MY ID” button in the center of the bottom row, which can be used as a members' card. Discount and special services are also available based on the annual purchase amount. Additionally, users can enjoy SHOPPING directly from the app, checking out favorite items and making purchases at any time. The LOOK feature introduces seasonal recommended coordinates, with the option to purchase your favorite items on the spot. Users can also utilize the SHOP LIST feature to find nearby stores and view their information. The app also provides push notifications to deliver the latest news, coordinates, and deals to users, and SNS information can be easily accessed and viewed.
