Tks Bob,
Guess the apps are not that expensive in the first place
Appreciate the heads-upOnce you've bought them, you can re-download them at any time so long you are using the same Apple ID. You never have to pay for them again. But if you back up your device on your computer first, then restore the new device using that backup, you won't have to bother re-downloading them or lose any data.
They do not somehow magically download to a new device.
All app purchases are tied to your Apple ID and are available for download from any iOS device that uses your Apple ID.
You can backup your old phone in iTunes and then restore that backup to the new phone.
