This is an application to reduce the amount of communication for a smartphone/tablet. It works by limit the application(s) that can communicate under certain conditions, such as when the screen is turned off.
By using detailed settings, you can use so-called firewall functions such as restrictions for each communication destination (country).
There are restrictions in the initial state, but the restrictions will be removed by email registration (free) or in-app purchase.
This app uses the functionality of Android's VPNservice to restrict communication. However, the processing is performed within the device(smartphone) without connecting to any VPN server.

With this app, you can do the following.

1) You can limit apps that communicate in a cellular environment (not connected to Wi-Fi) and with the screen off or on.

2) You can set up apps that can communicate in a cellular environment and only when the screen is on.

3) You can set up apps that can only communicate in a Wi-Fi environment.

4) It display the amount of communication for each application .

note 1: This app is available in the android 5.0 or later systems.

note 2: In the Wi-Fi only model (which means android devices disabled a cellular communication function), you can not use all functions.
I will recommend to use this app for a smartphone/tablet that have a cellular communication function.

Especially confirmed
- android 5.0
- VoIP app
