Is it possible to check how much data each app consumes over wifi. I am a seaman and onboard a ship. Internet onboard is very costly at 10$ for 500mb. As soon as i log into my wifi connection data gets consumed very fast.
I did not find any app showing data usage per app over wifi connection. And even it is not possible to block any app for wifi usage. Internet usage is costing a lot onboard here. Please advice as what could be done
