Nify

ローミング中にあなたが2G/3Gにあるかどうかを知らせるためにネットワークインジケータアプリ。

App which lets you know your current network type right in the status bar while you are roaming. Its a kind of network indicator app specially for nexus 5 devices.

In order to select the type of network in your android phone, you go into the settings and choose the network type. But the problem is, the network type you chose is the preferred network. This means if you have selected 3G then your smartphone may switch to 2G in case of unavailablity of 3G. This is alright as you can see the status as a small icon on top of your network symbol in status bar.

But the problem comes while you are on roaming. Instead of 2G or 3G symbol, you will see an R icon. Now you don't know on what network you are on.

In order to solve this problem, here comes Nify , a network indicator app. It tells you the network type as a small icon in your status bar.
