Does using an app on your iPhone use data?

Does using an app on your iPhone use data?

If it connects to the Internet, yes.

It's depend if that app using Wi-Fi then yes

Depends… An app like facebook would use data… But some games and pic editing apps etc don't use data ( but nowadays almost evrything does)

If it is connecting to the internet, yes.
If your phone is connected to Wi-Fi then it will use your home internet data.

Depends try to go somewhere where you get no service and if the game works no if it doesn't ya

Every app uses data and its free when you are on airplane mode

That would depend on the App, some apps require you to use data usage to function properly use as Facebook and twitter but not all apps require you to use data usage.

If you use broadband Internet. Then yes. But if you want it to stop use Wi-Fi

If the app is a game with levels/stages or something like angry birds or cut the rope, then no it won't. But if its something that requires you to log on to something, or is a game of 2+ people, then most likely it will use data.

If You Need Internet Like Netflix It Does Use Data But If You Have like Temple Run No You Don't
