This is okay for what it is but is essentially a one-hit wonder iPhone novelty app. Dont expect hours of entertainment from this, but it can be handy for those times when someone suddenly says during a conversation, "What are you, blind!?" Then you can snidely retort, "Well, why dont we check?" You get the picture; the app provides at least a *general* idea of visual acuity. My device: iPhone 3G S.
