Break Down iPhone Signal Strength with Bars
Submitted by Bob Bhatnagar on
The strength of your cellular signal can make or break a data connection or phone call. The iPhone is no different, and as iOS users already know the signal strength is displayed on the status bar in the upper left. You can use an app like Signal 2 to get more details about your signal and where it’s coming from.

Sound like too much information? Bars will give you more information about your signal while keeping things simple. All this tweak does is take the signal bars you’re already familiar with and make them better.
