A letter chart app designed to be used via AirPlay to a large screen (TV or computer monitor). Use either an Apple TV connected to a TV, a cable, or use a TV with built-int AirPlay such as the latest Samsung or LG.
And now you can also run the app directly on an Apple TV, without the need for an iPhone or iPad!
Has everything you'd expect, including multiple optotypes (sloan, illiterate E, landolt C, pictorial, international sloan) and multiple Visual Acuity nomenclatures (metric, imperial, decimal and logMAR).
The basic letter chart is free. Larger letters, further optotypes, other charts require an in-app purchase.
The charts you'd expect are all here:
- cross-cylinder charts
- binocular vision such as a 4-dot test
- duochrome
- confusion lines around single letters or a single row
- low contrast
- single line, both horizontal and vertical
- and more
You can even import your own images and videos to create your own chart.
Configure a chart then save it as a shortcut with a simple drag-and-drop operation.
Use Dark Mode for a dark consulting room.
Great for mobile workers, keep your chart on your iPhone and just take an Apple TV to connect to a television at your destination.
Use HomeKit lights in your consulting room? Have them switch automatically as you change charts!
Want to use Siri to control your charts by voice? Now you can!

Chart updates!
- There's a new fixation disparity / suppression chart in the binocular charts, with both horizontal and vertical options.
- I added a new Optotype to match International standard 10 letters. The random function on the original chart still only shows the standard 10 letters, but the new optotype has new default charts that display only those 10 letters.
Upgrades!
- You can now choose the colours for the binocular charts. Use red/green instead of red/blue? Just set the colours accordingly. The "binocular" colour will be automatically calculated for you.
- You can now view and delete saved monitors in the settings screen.
- The calibration / settings screen has been improved to show the colours and also a sample letter.
- The fan chart has been moved to the astigmatism charts section, which just makes a lot more sense.
Bug fixes!
- Fixed monitor settings sharing between devices. Your monitor settings won't disappear anymore if you're using multiple devices.
Keeping up with the Joneses!
- Supports iOS 26
- Minimum iOS version is now 15.6.

- I added a new optotype (digits), which is the numbers 0 to 9 in the same font as the main letters.
- The "randomise" chart action will now pause/play a video. By default this means you can tap the screen to pause / play a video.
- Oh, and a BIG bug fix. You know how if you connect to AirPlay after starting the app, or it drops out and you have to reconnect and sometimes the scaling is off? Yes, well that's been fixed! Sorry it took so long to fix it!
