Is there an eye movement keeper app like those for passwords but for eye movements?

It's a bit like password managers where it memorises eye eye movement patterns and tells you if the eye movements are lower, right or left of previous habits, allowing you to build a narrative around why they might be right or left e.g eye movement is slower to right e.g lower, right or left and take note of the cause e.g. is it because of caffeine, time of day, lack of sleep, etc?
