280blocker

280blocker is a high-performance Safari ad blocker designed to block ads on Japanese sites. By blocking as much ad-related communication as possible, it reduces traffic and speeds up page display. It has been featured in several magazines and recognized in Japan for its effectiveness.

Note: this app only supports Japanese ads. A DNS-based blocking feature is available on a trial basis (iOS 14+). Some ads on video sites or non-Japanese sites may not be removed due to technical limits. If you have issues, follow in-app instructions and consider reinstalling. Updates to block lists and advanced settings may incur charges.
