Easy to use, unique

Using the depth camera, it tells you the exact distance from patients face to ensure reliable results. Very cool! No wifi needed or adds.

Excited to see what further updates are to come as it is pretty new but likely will use for years to come.

The perfect near card

This app is perfect for checking a patient’s near vision. It is simple and intuitive with several options for the optotype. It has no advertising and doesn’t collect your data. I love the full brightness button!
