1. Instead of a shake feature, a "Cannot identify direction" button would be betterThis app is good but it shows eyesight score after test as -0.3 and in simulation can't see this number so this glitch needs to be fixedplease change that "shake" feature when the child cant see the chart l.
2. shaking is sometimes usless and it adds hassle to the processI landed on 38mm/42mm.Like,hawk eye sight is what kind of surgeon variety im looking for.Not calibrated for Moto G7 power display.Can I use this app in my tablet instead of my phone, if the calibration is right?Not for self use.
3. The only minor issue is that you have to find out how to shake it when the letter is unreadable.This needs more letters besides "E".
4. After a little while you can come to recognize the shape of the letter and discern it's direction that way, even if the letter is blurry or ouf of focus.
5. Found out that one of my twins had an eye issue with this app during covid when we were worried about stepping out.
6. It's very easy to use, and truly remarkable in bringing easy eye testing to almost everyone with a smartphone.
7. Must have second person to administer test.
8. When we later went to the doc, it corresponded quite well.
