Cloudflare has released its mobile app, WARP, which secures all internet traffic on a user's phone using their global network. The launch comes after a longer-than-expected wait due to the complexity of building a next-generation service without slowing down connections or draining battery life. Initially announced in April 2019, WARP was expected to roll out by July but faced challenges with diverse mobile networks and operating systems. The app is now available for free on iOS and Android devices, with an optional subscription for the faster version, WARP+.
