What you cannot test with RealEye
There are some limitations in using RealEye.
The live website test won't work on mobile devices (smartphones).
RealEye platform works best on Chrome web browser. It won't work on the old version of the Edge browser, it only works on the latest Edge version based on Chromium.
It’s important to remember, that there is a drop-rate (number of participants that failed to successfully take part in the study) and an offset (number of tests that are low quality). RealEye is aware of this fact and always orders more participants, so the data it provides to you is without these issues. However, you have to remember that when you use your own participants you need to take it into account.
