iPhone and iPad Apps can stuck on "waiting…" or "installing…" state while trying to download, install and update apps on the iPhone (including iPhone 5/5s/SE/6/6s/7/7 Plus). The app is frozen with a "Loading…" or "Waiting…" under the icons which are greyed out. It's annoying, but there are a few tricks and fixes.
Solutions below apply to both iPhone and iPad. We'll take iPhone for example to show you the process.
To force restart iPhone 7, iPhone 7 Plus or later:
For iPhone 6s, iPhone 6s Plus and earlier:
If the stuck continues, you might need a special tool to force iPhone to reboot. Tenorshare ReiBoot is one you can trust, small in size, free of charge. Besides the app "waiting" stuck, it also fixes other sorts of iPhone stuck including Apple logo, black screen, red iTunes logo, etc.Connect iPhone to your computer and launch Tenorshare ReiBoot, it will detect your iPhone. Press "Enter Recovery Mode", and when you see the "Enter Recovery Mode" greyed out, press "Exit Recovery Mode". iPhone will restart itself.
After restarting iPhone, the app that is stuck at "Waiting…" should be gone from the home screen/springboard. You can then re-download the app.
Sometimes, apps stuck at "waiting" during downloading because iPhone is running out of space. Head to Setting > General > About to check for detailed information. Of course, you can try to delete unwanted apps/games by tapping Setting > General > Usage > Manage Storage (Storage), find the app > Delete App.
When iPhone stuck in "iPhone app waiting" state while downloading apps, you can follow the instructions to re-download and reinstall the app.
Follow the onscreen prompts until the app is successfully downloaded and installed on your iPhone.
If you do not have a stable data network, you might fail downloading or install new apps. For 3G/4G/LTE users, make sure there aren't network issues. For Wi-Fi users, restart your router or connect to another Wi-Fi network and see if it solves the problem.
Once the network is stable, you still need to delete the app you are trying to install, re-download it and reinstall from App Store.
If it is error with your App Store, you can sign out of your Apple ID and re-login.
All goes well, these tricks will be sufficient to fix iPhone app stuck on "Waiting" during installation or downloading. If not, leave us a comment below or on Facebook and Twitter. We could discuss and see if there are other fixes.
