If you're willing to put up with some ads, Hotspot Shield VPN is a free app that aims to make your Wi-Fi connections secure and protect your privacy while online.
The interface is clean and simple, and aside from a few options, there's not much for you to do. Hotspot Shield VPN is basically ready to go as soon as you open it. It's capable of optimizing data flow, providing you with a little more mileage when using 3G or 4G networks (depending on your unit), and further encrypts your sent data so that info and messages will not be intercepted by a third party. It also shields your IP address, so you can surf anonymously. Although most of what this app does is behind the scenes, we didn't have any issues in our tests, and connectivity was smooth and trouble-free. One downside to this simplicity is that you don't have direct control of the app. Instead, Hotspot Shield VPN adjusts settings and connects to networks on its own. The other is that the free version is supported by ads and doesn't give you access to customer service 24 hours a day.
If you frequently browse the Web or send and receive data with your Android device, Hotspot Shield VPN offers another layer of security to protect you and your information. You'll have to put up with a few ads if you decide not to upgrade to the paid version, but that seems a small price to pay for peace of mind.
