How do i transfer apps from one iPhone to another
There's no direct-transfer of apps that I'm aware of. If the phones are signed into the same iTunes account the app should be downloadable from the app store on the 2nd phone, assuming the phone's iOS version &amp; model is compatible.

Alternatively you can transfer your apps from the 1st iPhone to iTunes and then onto the 2nd iPhone but this only works if they're both signed into the same iTunes account.
