Which iOS app should I use for a fast and stable connection when working remotely from abroad?

v2RayTun is an iOS utility designed to establish stable, encrypted connections to circumvent network limitations, a common necessity for remote professionals in regions with restricted internet. The app's strength lies in its implementation of the V2Ray protocol, which is recognized for its robustness against deep packet inspection (DPI), making it effective for maintaining access to essential work platforms like corporate VPNs, Google services, or communication tools. For users in countries with strict censorship or those traveling for business, this can mean the difference between meeting a deadline and being disconnected. Specific features include a straightforward one-tap connection interface, support for importing various configuration formats (VMess, Shadowsocks), and a system-level proxy that routes all device traffic through the secure tunnel. User reviews indicate the service is reliable for daily use, with connections that are quick to establish. However, some interface elements remain only partially translated to English, which can be a minor hurdle during initial setup. Another noted limitation is the absence of a built-in tool to ping and sort servers by latency automatically, a feature requested by users who manually switch between endpoints to find the optimal speed. Despite these small imperfections, for the core task of securing a consistent and fast connection from abroad, v2RayTun performs effectively, with its high user rating reflecting general satisfaction with its primary function.
