Preserving the song and the feeling of that day: Music community app 'CHECKERAP' to be released on May 29, 2026

CHECKERAP Inc. (Headquarters: Akabane, Kita-ku, Tokyo; Representative Director: Kosei Funaki) will officially release the music community app 'CHECKERAP' on the App Store and Google Play on May 29, 2026. The app is designed to consolidate the music fan experience, featuring functions to record songs and 'feelings at the time,' manage live schedules, organize photos, and share memories with friends. The app is free to use and operates on an ad-supported model at launch.

Background of Development In recent years, services for music fans—such as streaming, social media, live booking sites, and setlist sharing platforms—have become fragmented, forcing users to switch between multiple apps to record a single experience. Meanwhile, existing social media platforms often fuel a desire for validation through visible metrics like 'likes' and 'follower counts,' which can hinder the pure recording and sharing of music experiences. CHECKERAP was developed to solve these issues of 'information fragmentation' and 'SNS fatigue' by providing a single space to record and share music, emotions, live schedules, and memories.

Key Features 1. Music x Emotion Posts: Users can record their feelings alongside the music they listened to or live shows they attended. Posts can link text, images, music, and artists. 2. Group Functions and Albums: Users can create groups with friends to exchange messages, share posts, photos, and manage live schedules. 3. Live Schedule & Setlist Management: Centralized management of upcoming live events and festivals. Users can see which events group members are attending. 4. Profile QR Sharing: A customizable profile screen allows for instant contact exchange at live venues via QR codes. 5. Differentiation from Existing SNS: The app does not implement a 'like' function to avoid fueling validation-seeking behavior. It includes standard safety features such as reporting, blocking, and muting.

Technology and Patents CHECKERAP Inc. holds patents (No. 7787629 and No. 7840518) for technology related to check-in-based reward distribution and incentive design for collective behavior. These patents have potential applications beyond music, including events, regional tourism, commercial facilities, and community initiatives. CHECKERAP is the first service to utilize these patented technologies, and the company plans to expand into non-music sectors in the future.
