Worthless
Just a scam
The best snellen chart phone app
Excellent app. Automatically adjusts to correct size for screen and measures the distance from patient to screen
Doesn’t work
This app doesn’t work properly. You cannot use it without entering your email address. When entered it is not displayed properly. The two links at the top of the Settings page do not work together with others. When you click the info icon the information page overlays the chart and cannot be removed. Obviously no Alpha testing done.

Good for basic test
The randomizing feature on the free eye tests works well.
Excellent
The best eye chart. Have been using in the ER for years. Excellent. Holding at the end of the bed is approx 4 feet for most patients
