Speed vs Redundant Mode
Speedify supports two modes: Speed, for fast performance, and Redundant, for the ultimate in reliability. To be clear, unless you are certain that you need Redundant mode, you should pick Speed!
The two modes are:
Speed: This is the normal mode, where Speedify sends each packet of your data on one connection at a time. For a speed boost it may send some data on one connection, and some data on the other connection, but each packet of data is only sent once.
Redundant: Redundant mode gives you super-reliable Internet by sending all of your data over both the Cellular and Wi-Fi connections. It uses a lot of data and a lot of battery power so it's not recommended for normal usage. It's more appropriate for protecting very important sessions such as a business call over Skype or live streaming a video to an audience. We have a number of reporters and people live streaming video who love Redundant mode, but it's not for everyone.
To change the modes:
On the main screen, Click the gear next to the Connection status :
Tap Session, to pull it up, then tap Redundant mode picker:
If you are not sure which one to use, pick Speed!
