This app is a scam!
Response from developer
The application starts with Numbers appearing in numerical order which will disappear. You have to tap the boxes where you saw the numbers. This is the introduction to the training and works as a cool down after a failed completion. The next phase the boxes will in an abnormal sequence however you still have to tap the boxes in numerical order from lowest to highest. You have to remember what box number 1 was in and number 2 and so on and so on.. Haptic feedback will be added in the next update so you are sure that a box was tapped. Apple has strict testing and submission so please don’t accuse the app of being a scam.
