These records come from browser storage on this device. The “Create card” button renders an image locally in your browser and downloads it directly; Ruth Technology does not receive the result.

A slower or lower latest result is normal. Short challenges vary from attempt to attempt. The useful question is whether your personal best and recent trend improve over repeated visits.
