Apple makes this incredibly simple! You can swap any of the Apps you got through the App Store to/from any of your devices, as long as you have the same App Store account on all devices.
- Open App Store on the device that you want the Apps loaded to, on iPhone select "Updates" tab - - on iPad select
"Purchases" tab.
- This will open a list of Apps you have purchased (free or paid),
- select "Not on this iPad/iPhone", which will display the Apps you have purchased through the App Store to a
different device but not on the device where you want them loaded.
- You will see a little Cloud to the right of each App.
- Simply click/touch the Cloud & it will begin to load to the device that you are working from.
- As each App finishes loading, select the next App to load and continue down the list until you have finished loading
all the Apps that you want on that device.
Apple, you need to post this method on your website instead of directing people to backup on the Cloud, setup Sharing, reset their phone and various other methods that I found. You have created a great way for your customers to perform this task, take credit for it. I literally spent 4 hours Googling for answers until I found a YouTube video that showed what I just explained.
