Does using apps on iphone mean internet use?

So apparently i'm over my limit on using the internet even though i don't remember ever really using it that much so i was wonder ing do using apps mean internet use, like Pandora, Family Feud, Spotify?

Yes because you DO need Wi-Fi (Internet) for those apps.

Yes, most apps use data
pandora is streaming music of the internet, so it uses a LOT of data
same with Spotify

Family Feud probably uses a little for advertisements

On the iphone if you push home buttin twice the apps you used recent will pop up you have to hold your finger on the app till you see a X then push the X for all of them
That will make sure your not using them then it won't waste data. If your using a Wi-Fi connection it uses no data no matter what you will have unlimited internet etc.use

Yes, actually All of those apps you listed use internet, but not All apps do. Just the ones you said. Pandora is INTERNET radio, For family feud, for some reason it needs to be connected to an internet source, possibly to get the questions.

You can use Wi-Fi in your home to be able to use the apps
not all apps require internet
pandora does and spotify also does
hope i helped.
