How to install the app...
How to install the app depends on the make of your phone. Note: QR scanner apps may not open the app in the browser on the phone. To open in the browser, tap options (Android) or the send/save button (iPhone) and select "open in browser." Then,
With the app open on the phone, just touch the share box with arrow and confirm “Add to Homescreen.”
To ensure proper operation of your app, make sure that you have installed the latest updates to the iOS operating system.
For newer Android, while viewing the app, tap the three dots that indicate more options and choose "Add to homescreen." On some older Android, tap the "More" or "Options" menu (three dots) and select “Shortcut." You might otherwise need to select "Bookmark" and then, in the “Save to” drop down menu, select "Homescreen."
On Blackberry, with the app open in the browser, hit the menu or "More" button (looks like a group of dots), then click on "add to home screen."
