MVTX App - Pending release on Play Store

The objective of the app is to create a way for patients to take an eye exam from home to reduce the stress and time of having to visit the clinic and to track progress of medication and degeneration of eye health. There are multiple different types of eye exams in the app that will test the acuity of the eye, which will help to diagnose the effects of disease and the progress of medication on those effects. My purpose there was to work with the onsite US team based out of Belmont to develop the preregistration, registration and exam completion features of the MVTX app.
