hello there, how can i transfer apps from iPhone to an iPad?

Are you attempting to transfer all data and Apps from an old to new device, or simply install Apps that you have already installed on one device on another?

Purchased Apps are forever “tied” to the AppleID account from which they were purchased. Apps that you have purchased are available for installation on other compatible devices that are signed-in to iCloud and App Store with the same AppleID account. If you are signed-in with the same AppleID, just download from the App Store.

If transferring data from one device to another, Apps are not directly transferred between devices. For Apps, the transfer process creates a record of the Apps that are installed on the donor iPad - and it is this record of installed Apps that is transferred to the target device. For Apps that are still available for download from the App Store, the corresponding Apps are then automatically downloaded and installed from the App Store.

Not all Apps will, necessarily, continue to be available. Apps may have been removed or retired from the App Store by the respective App Developer. Some Apps may have been abandoned - and may not be compatible with the new device. Where a compatible App is not available, you’ll not be able to transfer/install the App. 

You can't "transfer" Apps.

If an iPad App is available download it from the App Store.
