Visual Acuity Charts App Reviews

convenient and accurate. At least in iPhone XS Max, the letters displayed are precise as I had measured with a ruler.

I tried a few eye chart apps however, most are just replicates of paper based eye charts. This one utilizes advantages of iPhone, delivering pretty user experiences while maintaining accuracy of detecting near-sightedness.

Mirror mode is great. Easy to use.

I have been wondering how come the top row of the Snellen chart could be suitable for both 20 feet and 6 meters, as marked in paper base Snellen charts, since 20 feet is 6.096 meters. This app actually gives slightly larger optotype for a 20 feet distance than for a 6 meters distance. The UI design is mobile friendly. The hint is brief, so it took me some fail and try to figure out how to use. After all, intuitive and smooth.

I rarely use metric. It would be great if I were able to switch units to english. Thanks

If free, this would a useful addition to the urgent need for teleophthalmology in the COVID 19 age. But as a charged for app, why bother.

The mirror mode is handy and interesting.

My only suggestion is maybe have the letters appear in a row going down. Top can be 20/200 and the bottom is 20/20. Would make great for bedside screening

Wish this app included 20/400 and beyond. Could you add larger optotypes?

App was free a few days ago now patients have to pay because they need it because of covid19 Pretty bad and lacking human decency
