Quality thresholds you can check yourself
We specify all the thresholds in the table below in the contract. Before handover, you receive a quality report detailing what we measured, which tools we used, when we measured it and the results. You can repeat every measurement yourself for free, using the same tools we use. If a score is lowered by a third-party service or module that you have chosen to make mandatory, we record this as an exception before acceptance.
In addition to the thresholds, we check 9 reference screen widths, from 360 to 2560 pixels, so that nothing is cut off or shifts sideways on a phone or a large screen.
