It displays your internet speed test results and status bar for 2G, 3G, 4G, and WiFi connections. The app is essentially a bandwidth monitor, speed test, and data monitor in one.

One of the great features of this app is that it provides daily and monthly usage records for both internet and WiFi data. It also displays the date in the right-side corner of the screen. The notification dialog is another useful addition, providing users with a clean and unobtrusive notification that displays upload/download speed and daily data/WiFi usage.
