How to stop apps from going from one device to the other?

Okay, so i just recently got a new iphone c.
When ever i download apps on it, it goes onto my moms ipad. I know it's because we're using the same apple id but on my old iphone 4s, it didn't do that. Same id, password, everything. Is there a way to stop them from going onto my moms ipad? My friend said there's a way to but i don't know if i should believe him.ty.

You should just sign up for your own apple id, but I believe you can turn off icloud to stop that.

I think you have to turn of the cloud feature i don't know for sure cuz I have an iPhone 4S

The only way to stop it is to set up your own apple account. Reset your iPhone to defaults from the settings app. There's a restore option in there. It will delete everything you currently have and then you can add apps under your own id.

As long as you use the same Apple ID everything is shared.
