The EveryHere App will work on any Android devices that runs on the Marshmallow (6) version or higher with a rear facing camera. If you want to use the rear facing camera to scan barcodes, the device will need auto-focus. Auto-focus is not a requirement for scanning QR codes, but is recommended to ensure scanability in most scenarios.
If you are in the market to purchase devices for event day, we suggest the following low-cost devices:
Nexus 7 by Asus 2013/2nd Gen (Autofocus)
Samsung Tab 4 (7in) (No Autofocus)
Lenovo A3000 7in or 8in (Autofocus)
You can download the app HERE.
PRO TIP: When printing QR codes for the bib/attendee ID scanning, the recommended minimum size is 1.2 x 1.2 inches.
