How Can I Get The Lost App Back To My Phone? Here's The Answer.
All apps can be redownloaded from the App Store. You may have deleted it or you may have just “misplaced” it by accidentally moving it to a folder.
If you swipe down from the top or swipe right until you get to the Notification Center, you can use the search to find your App. If it is misplaced, it will show its folder location or if you deleted it, it will provide a link to the App Store.
