In plain English

SpeedUp VPN is an Android app that lets you browse the internet privately and get around network restrictions. It comes with built-in servers already configured, so you can start using it right away without hunting down your own connection details. If the provided servers aren't enough or you'd rather use your own, you can add or import custom servers as well. The app works using something called ShadowsocksR (SSR), which is a protocol designed to help people bypass internet censorship. When you turn the VPN on inside the app, your phone's internet traffic gets routed through one of these servers, which helps mask where you're browsing from and what you're looking at. It's built on top of existing open-source ShadowsocksR projects for Android, so it's essentially a customized version of that underlying technology with some ready-to-use servers added in. The main audience here is people living in or traveling to places where certain websites and online services are blocked. The project is clearly aimed at users who need to circumvent those restrictions, the included links point to resources about getting past internet firewalls. If you've ever found yourself unable to reach a site that should be freely accessible, this is the kind of tool that helps with that. One thing worth noting is that the project encourages people who build the app themselves to change the application identifier before compiling. This is a small but deliberate step to avoid the app being detected and potentially blocked by systems that look for known VPN applications. The whole project is open source and freely available under the GPLv3 license, meaning anyone can inspect, modify, and share it.
