Why do I keep receiving an "Oops" message when I open the EyeQue PVT app?

There are a 2 main reasons that you might be experiencing this message on your device:

1. You may be unable to connect to the EyeQue Cloud:
   • If you have limited, interrupted or no internet access you may not be able to connect to the EyeQue Cloud server.  Without a connection to the server, your device cannot be verified and it will prompt you with this error.  To re-establish a connection on an iOS device you will need to force close the app and the reload the app on your device.  This should fix the issue and you'll be able to continue with the test.  On an Android device you can tap on the "Try Again" button or force close the app like an iOS device.  If you are still receiving the error, please contact support at [e-mail] to see if the issue is server side.  If you are using an Android based smartphone, do not use the back button as it may leave any errors on the stack causing you to continue to see this error.
2. You phone is not compatible with our device:
   • Depending on the device that you are using, we may have not tested the device for compatibility or the device is not usable with the Personal Vision Tracker system.  There is one main requirement that will determine if your device has a possibility of being compatible and that is the pixel per inch of the screen.  If the current device has a PPI below 250 then it will not give an accurate enough reading with the EyeQue miniscope and will not be compatible.  If your device does have the minimum PPI required, then it will not work.
