VisStim is a free tool providing common flash card shapes used by professional sensory therapists in their treatment programs for brain injury. VisStim also features colour screens for light therapy. The colour screens are usually used in a dark room to train the brain to follow colour and simultaneously provide a yard-stick for estimating brain development.
The tool can also be used in the early life cycles of babies as a source of visual stimulation.
The application is completely free, with no adverts.
The application is intended for use as directed by your medical professional.
