?Your app doesn’t finish downloading.
First, make sure that your network connection is active. The App Store should detect that your download was interrupted and should continue it whenever your connection is restored. If this does not happen, visit apple.com/support/itunes.
?Your app is crashing.
First, try restarting your device: Hold down the power button until the screen reads “slide to power off.” Power off the device by moving the slider. Once it’s fully shut down, turn the device back on and then try restarting the app.
If that fails to solve the issue, make sure your device is running the latest version of Apple’s iPhone OS. To verify this, sync your device with iTunes on your computer. Another recommended step is to make sure you have the latest version of Apple’s iTunes software. To verify this, launch iTunes and select “Check for Updates” from the Help menu.
Lastly, if you sync’d your app from a computer to your device, it’s possible there was an issue with the sync. Try uninstalling the app and then re-sync. If your app continues to crash, please post a comment in the next step of this feedback form.
?You want to uninstall an app.
First, press and hold the app icon until all the icons start to wiggle. Then tap the "x" in the corner of the app you want to delete. Tap the “Delete” button to permanently remove the app. Press the Home button to return to the regular menu. NOTE: Uninstalling will remove all app-related data from your device, too. And, if you do not have a backup on another device, you will need to re-download from the App Store.
