Difficult to scan

It’s very difficult to scan the codes. For anyone struggling you need to zoom in (move closer to the code) on the camera test to be able to scan it. Then for the patient code you need to keep scanning until it works. Keep persevering, don’t give up, it’ll eventually work. I scanned for 25mins until it worked. Also some words are cut off in the app, no idea what it was saying

Waste of time

App doesn’t scan the device and there is no option for manual scan. What a waste of time.

App won’t take a picture of the results

The app only gives you two minutes to take a picture of your results and then says they are invalid. 2 minutes would be enough time if it didn’t constantly give lighting errors and control line errors. Waste of time, and now I have to request a different kit for testing.

Camera does not work

Took forever to get the camera to work, therefore the test result trimmed out giving me an inaccurate result. Also not supported by newer iPhones so I had to borrow someoness phone to do the test
