HosPortal does not have a separate app to download, which means it is accessible from any device on any operating system,
However if you use an iPhone or other Apple iOS device, such as an iPad, you can save HosPortal to your home screen as if it was a separate application, like shown in the screenshot below (A).
To add HosPortal to your home screen
On your iPhone or iPad, you will need to use the a web browser such as Safari or Chrome.
Go to the HosPortal homepage (https://roster.hosportal.com/) and log in. Or go to any page you are already logged in to. Then select the share icon (B):
Then select "Add to Home Screen" (C) and select "Add".
If you do not see the "Add to Home Screen" option you may need to swipe up to see the full menu (D).
The app will then appear on your Home Screen, and can be moved like any app icon.
You can also change the logout time to reduce the need for entering your password each time you access HosPortal. See this article here.
