### 2/5 — Full of bugs

*2018-06-27*

This app needs work to fix all the bugs it has! You select one type of eye chart and get another - and it’s completely random because each time seems to be a different one. The remote app also works only some of the time. 
The app has potential but IN ITS CURRENT FORM IT IS NOT WORTH THE PRICE.

### 5/5 — GREAT APP

*2013-01-09*

I have been using this ipad app for over 6 months without any problems.  The instructions on the website are very good, and emailed questions were answered quickly.  

I highly recommend it for eye doctors looking for something other than a projector or the prepackaged acuity chart systems.
