Echo Accelerator is a professional audio and video accelerator with core technology, enabling one-click acceleration for popular Chinese apps like Bilibili, iQIYI, Tencent Video, QQ Music, and NetEase Cloud Music. Built on an enterprise-grade SDWAN acceleration and encryption technology, it ensures a smooth experience while protecting your privacy and security. Unlike traditional proxy-based acceleration, it offers better application compatibility. Echo Accelerator provides a long-term free trial package to build a better product experience through user feedback.

Echo Accelerator innovatively supports one-click access point switching without needing to restart the VPN connection. It also supports intelligent routing and switching, ensuring a seamless experience.

Using smart traffic diversion technology, Echo Accelerator ensures a smooth return to Chinese applications without affecting your local apps. With a professional network engineering team, we carefully select, maintain, and dynamically update data for both domestic and mainstream foreign applications, ensuring a seamless experience for both.

Echo offers a long-term free quota for you to enjoy, and we welcome your feedback and suggestions. All users can contact us through the problem feedback button in the app.

VpnService Permission Explanation: The core service of Echo Accelerator is to help you access domestic applications using our premium network lines, so it requires VpnService permission on your device. You will be prompted to authorize this on first use. All your traffic with the VPN access point will be encrypted using ChachaPoly1305 encryption. We comply with local laws and regulations and only route traffic to domestic network addresses back to China, with foreign traffic handled by your local network.

Important Note: This product is exclusively for overseas users to accelerate access to Chinese applications and does not provide service for users in mainland China or offer "wall-crossing" functionality.
