Made by Dr Robert Burke at Calgary Vision Centre, the Parks 3 Step app aims to simplify the potentially troublesome binocular vision test for those practitioners with an iPhone (it's not yet available on Android). It's up on the App Store for £0.69 ($0.99).
The actual test is performed by tilting the iOS device in the manner of the patients head, in the order the app specifies, it will work through the Parks 3 Step with you and give you an astonishingly accurate response.
Graphically the user interface is sparse and in some places plain ugly. Whilst I can understand this is not the main emphasis for a clinical application when I'm buying an app I really to expect a certain minimum effort on this front.
There's no audio in the app, a spoken guide would have been a useful feature.
Parks 3 Step is available now from the App Store for £0.69.
