See an app or design on a screen in a room, in shade and in direct sun at different brightness levels, with the contrast that is left for text.
Use the guide alongside the working tool.
Open Sunlight Readability Simulator →Pick the exam and document
Add an app screenshot or design, or try the sample.
Frame and clean up
Choose indoors, shade or direct sun, and the screen's brightness.
Create and check
Read the text contrast left in that light and export the comparison.
Privacy and limits
Reflections are modelled as 5% of daylight spread evenly; real screens differ in coatings and auto-brightness. The image stays on your device.
