Introducing the world first android professional app for all eye tests.

For eye care specialists, convert your smart phone or tablet or a LED screen to a 4,000$ worth visual acuity examination device. Use it in your clinic, home visits or anywhere you like.
Easy to set for screen mirroring on a LED screen or direct installment on your smart TV for bigger view at your clinic.
Use another smart phone as a smart remote controller for the tablet or smart TV you use as a projector.

The chart size is calibrated at any distance or screen size. It's calculated dynamically with the accurate optical equation along with the related medical aspects to introduce to you the most accurate optometry chart on an android device.

You get some vision charts (including Landlot-C chart) and other tests (including color vision plates) completely for free for lifetime.
And you can purchase a Pro licence inside the app to have all these charts in one place:

* Landlot-C chart.
* Landlot-C chart without the oblique (45°) angles.
* Tumbling E chart.
* Alphabetic chart.
* Numbers chart.

& Units: Metric (6/6), Feet (20/20), Decimal (1.0) and LogMAR.
& Modes: Complete rows & columns, one row, one column, single sign.

* Duo-chrome test.
* Red/Green filter applied to any chart to make a custom Duochrome test.

The app behavior is fully customized according to your practice including default chart, default acuity row, default row step (0.1 Decimal or 0.1 LogMar), default signs (optotypes) distribution over the test area, default spacing between the optotypes, etc...

All these features are available for a trial period enough to try them in your daily practice for days after which you'll have to either purchase the full licence with a relatively small fee or continue using the app with limited features.

And it won't get better without your feedback. So, you're welcome to send us your feedback, suggestions, bugs reports.
