It is one of the most common problems in mobile phones and tablets. Usually, when you open an app, you will see a black screen for a few seconds and then the app will crash with or without an error message. There are a few ways to fix this problem.

1. Most of the time, it might be a temporary loading issue. You just need to press the recent applications menu (usually the first left button) on your phone. Then you close the app that has this issue. Now open the app again. It may work normally.
2. Try to restart your iPhone / iPad. Press the power off button for a few seconds and then choose restart from the menu to restart your device. Now you can try opening the app, it may work fine.
3. If none of the above is working, you can wait till your phone battery drains and it turns off automatically. After that put it to charge, and press the power button. It may work after this.
4. Finally, if you can't fix it with anything, you may need to uninstall the app and reinstall it. iOS usually provides an option to restore settings and content from iCloud backup, if you've enabled it previously.
5. Even in some rare cases, the re-install step also doesn't work. If that is your case, try installing older versions of the app. Good luck!
