StimuliApp is an app designed to create psychophysical tests with precise timing on iOS devices (iPad and iPhone). Psychophysical tests are tests to assess perceptual capabilities. With a simple system of menus, different types of tests including the most common stimuli (gabors, random dots, images, sounds and videos among others) can be created. Programming skills are not necessary. Features: - Precise timing (frames are not dropped) thanks to the use of the native framework Metal, which provides a direct access to the GPU of the iOS device. - Option to run tests at 60 or 120 Hz depending on the model of the device. - Visual and auditory stimulation are synchronized. - Interactive creation of stimuli using real-time preview. - Possibility of using different spatial and time units. - Gamma-correction features. - Automatic report generation.
