With is a Japanese dating app that focuses on connecting people based on shared interests and hobbies. Users create a profile that includes their interests, favorite places to go, and things they like to do. The app then matches users based on those shared interests and suggests potential matches for them to connect with. With also offers various features such as a messaging system, a search function, and the ability to “like” or “pass” on potential matches. The app is free to use, but there are paid options for additional features.
