Hi jchamboc,
It may help to force close all open apps and reset your iPad by holding the Home and Sleep/Wake buttons together until you see the Apple logo on the screen.

Turn your iOS device off and on (restart) and reset

If the apps on your iPad are still quitting unexpectedly, the next step would be to reinstall iOS on your device by placing it in Recovery Mode, then choosing Update in iTunes.
- Make sure that you have iTunes 12 or later on your computer.
- Put your device in recovery mode.
- When you get the option to restore or update, select Update. This will reinstall iOS without erasing your data.
If your iPhone, iPad, or iPod touch doesn't respond or doesn't turn onhttps://support.apple.com/en-us/HT201412
All my best,
Allen
