The 1.1 version of PyEPL for Mac was available to download on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. This free software for Mac OS X is a product of Aaron Geller & Per B. Sederberg. The application lies within Education Tools, more precisely Science. Please check the Mac app with an antivirus before launch as it is downloaded from the developer's website, and we cannot ensure that it is safe.
From the developer:
PyEPL (the Python Experiment-Programming Library) is a library for coding psychology experiments in Python. It supports presentation of both visual and auditory stimuli and supports both manual (keyboard/joystick) and sound (microphone) input as responses.
You may want to check out more software for Mac, such as Genealogy Pro, sciatrope or Curvus Pro X, which might be similar to PyEPL.
