## What is Snellen test?

The Snellen chart is a widely used tool for measuring visual acuity. Named after the Dutch ophthalmologist Herman Snellen, who created it in 1862, this chart helps assess eyesight. To get started, choose a vertical surface to display the chart, stand 6 meters away, and aim your device’s rear camera at the surface. Once the chart loads, you can adjust its position and size via the control panel or directly on the screen using drag-and-drop, rotate with two fingers, or zoom in/out gestures. Need to switch surfaces? Just tap the button with the two circular arrows. You can also mute the sound or hide help texts using the appropriate buttons.

### 1/5 — AVOID

*2026-07-23*

Doesn’t work at all!
No support.

### 1/5 — Does not work - should be removed from App Store

*2022-10-25*

Does not work as expected. Just displays what is in the camera. No chart. No test. Just the camera. 
I might as well use my own camera as at least, it has options. 

This shouldn’t be a paid app as it provides no value. Stay away !!

**Developer response:** You must have good lighting. The program will not work in a dark room.

### 3/5 — Ошибка после нажатия плей и просьбы отойти на 6 метров

*2021-02-04*

На iPhone 6S после загрузки Тальцы - нажимаешь плей - тебя просят отойти на 6 метров . Начинается отсчёт и приложение вылетает домой телефона. Переходишь обратно в приложение и приходится настраивать все по кругу . И  там пока не влетит. Почините пожалуйста или подскажите что не так.

**Developer response:** Попробуйте в Настройках отключить звук (скобка вниз наверху > значок динамика). Не поможет - отключить текст (значок T). Пожалуйста, напишите результат.

### 1/5 — Не работает на 12 pro
