To run Loyalzoo on an iPad, please follow these instructions (will also work for iPhones):
Open the Safari browser, and go to store.loyalzoo.com
Tap the share button and choose "Add to Home Screen"
Type your business name, or leave it as "Loyalzoo Store"
Click Add. You will then find the app on the iPad home screen.
Then login and you're set up is complete. The app will not log out, and you will not need your login details to launch it in future.
Just repeat the above process for any additional account :-)
