Description
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:
& Crowding effect/phenomenon applied to any 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.
* Worth 4 dot test. * Schober test * Amsler grid with 4 different color/background combinations. * Color vision test (Ishihara charts). * Contrast sensitivity test applied to any chart with the selected visual acuity size. Units: CS log & percentage. * Optokinetic drum with the ability to change speed or width. * Cross-Cylinder test chart. * Astigmatism clock. * Fixation target. * Fixation dot. * Children fixation targets. * Cross Grid.
* Videos gallery & in-app player for playing patient education or children fixation videos. & In-app images gallery with enhanced image viewer.
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.
Recent changes: Improved faster optotype drawing processor New tests in versions 5.0+: * Cobalt blue screen * Arabic & Hindi alphabet letters charts. * Negative (White on Black) charts * Fan & Block astigmatism * Schober test and Vertical/Horizontal alignment for measuring squint angle.

★★★★★Nashwa Zeater· Oct 12, 2022
Great app. All the tests are included, and it's easy to use
★★★★★Ahmad Tabl· Mar 29, 2019
Ideal for ophthalmic clinic. No need for expensive screen charts or projectors. I use my PC full hd screen and my home Wi-Fi dongle and my mobile. This method has better brightness and black white contrast than my chart projector.

**WARNING: SCAM** Unbelievably bad. Cumbersome, non-intuitive UI. The developer thinks YOU are complete moron who will pay $85 for basic graphics. If had a couple of hours spare I'd be able to throw together a product far better than this, and ld just make it free. The quality is surprisingly poor even for a free app, especially the Ishihara color plates. I will keep looking fora $0.99 option - likely find a higher quality product. $85 for this?!? Gobsmacked.

Was not activated after I purchased the pro version. It says "Failed to activate this device". No activation code was sent either. I sent a manual request for activation code but no response. Had to contact Google to get refund. I really wanted this app!

Connection to internet is a bad idea, I got connection error when changing symbols. Good idea but need a lot of improvements. Lack of support is a big issue
