Time NetSpeed Monitor ( Google Play Store || Amazon Appstore || Github) puts an internet speedmeter on your any android device including Phones, tablets, Android TVs & Amazon Fire TV iterations (Amazon Fire TV, Fire TV Stick, and Fire TV Edition televisions).
The app displays the current time at the top right corner of your TV screen and it also allows you to add the current network speed in the upper left corner. You can select which of the two/both to display. The network activity is the live network speed being used by your device.
