아임인 is a finance app developed by TWAVE Corp for iPhone users. It is a platform where users can save and share money with other members. The app allows users to create money-saving groups called "스테이지" and choose the order in which they receive the saved money. Whether users want to save money quickly by participating in earlier stages or earn higher interest by participating in later stages, 아임인 provides the flexibility to plan their money-saving goals.

One of the key features of 아임인 is its 안심서비스 (Safety Service). Even if a user defaults on their payments, they can still receive 98% of the overdue amount immediately through this service, ensuring a safe and worry-free experience. The app also includes a social feed where users can share their stories and view stories shared by friends. Additionally, users can earn points through attendance check-ins and event participation, which can be used to purchase gift certificates and 아임인 coupons.

With its user-centered approach, 아임인 aims to provide a variety of services and upgrades in the future. For any inquiries, users can contact the customer support through the app or visit the FAQ section for frequently asked questions.
