## What is PsyPad?

PsyPad is an open source platform for facilitating visual psychophysics experiments on an iPad. Using customisable staircases or MOCS, the researcher can control presentation of any stimuli that can be precomputed as PNG image files, including movies. Features include participant accounts, up to 4 response buttons, comprehensive log files, and remote test configuration using the PsyPad server. A demo mode with access to a public gallery of tests also makes PsyPad useful for teaching.

The project is open source, with repositories for the application code and example server code.
