iOS/Android: Speedify is a handy way to combine multiple internet connections into one mega pipe. Now, it's even better. In 4.0, you can send redundant data over multiple connections, and get started without an account. The new Redundant Mode adds extra reliability by letting you send the same data over multiple connections at once. So, for example, if you're on a VoIP call and you want to make sure it doesn't drop, you can place that call over Wi-Fi and mobile data. This way, if one drops out for a moment, the other will hopefully pick up the slack and you won't notice the difference.
Speedify 4.0 no longer requires an account to set up. As soon as you download the app, you can get started. That should make it a little more appealing to anyone who was curious, but on the fence about creating an account to do so.
