Not reliable It all depends how fast the screen is touched not on acuity of vision. Uninstall
Great & precise This app is amazing to check your eye strain. Optician's should use this

Samsung S3 It works great! Thanks for Carl Zeiss vision make everything possible.
Application looks good but is it useful? While the application is implemented properly and looks good I am in doubt if it is of any value to the users. How it is supposed to work? It first offers you several options of smaller font texts until it finds what is the smallest text you can read on your device. Then it asks you to focus on some object six meters away. Once you get this it ask you repeatedly to focus on the screen of the device then on the far object then on the device each time waiting for you to announce that you are ready by tapping the screen. This process continues for a minute or so. Then the application announce that you have eye strain. Of course as curious as one can be I wanted to know at which circumstances the application would say that I had average vision and did not have much strain. To test this I tried tapping faster. My result got better. I tried again this time tapping even faster, say 4 taps per second and got the best result. Now I am wondering are the people with no eye strain able to refocus on distant and close object 4 time per second? Guess not :)
