OPIN 오핀 is a lifestyle app developed by powermobile.kr for Android devices. It falls under the shopping category and offers a range of convenient features for users.

One of the main features of OPIN 오핀 is the push notification system exclusively for app members. Users can receive real-time alerts about sales, events, and various benefits, ensuring that they never miss out on any important information.

The app also provides easy login and authentication, eliminating the hassle of logging in each time you shop. Even if you're not a member, you can simply register with your ID and email address to enjoy the perks.

OPIN 오핀 encourages users to invite friends and earn discounts, coupons, and rewards. By entering the referral code, both the inviter and invitee can benefit from this mutual promotion.

Writing reviews for purchased products is made effortless with the app's convenient review function. Users can easily write reviews and receive benefits with just a few taps, without the need to manually search for the purchased items.

Tracking deliveries is now a breeze with the one-touch delivery tracking feature. Users can easily check the real-time status of their orders with just a single click.

For app members, OPIN 오핀 automatically provides a mobile membership card. This barcode can be scanned at offline stores, allowing members to easily access their membership information, earn points, and enjoy various benefits in one seamless shopping experience.

Please note that the app requests certain permissions as required by the "Act on Promotion of Information and Communication Network Utilization and Information Protection."
