PsychoPy and Pavlovia for Phones

Hello all! I am just getting acquainted with PsychoPy for the first time and I would like to use Pavlovia and PsychoPy for a study with smart phone devices. I was wondering if you are building an experiment are there certain steps you need to take in order for it to be touch screen compatible so that you can have participants respond on smart phone devices? Are there certain devices these experiments won’t work on?

Thank you in advance for any help people can provide for this newbie!

I struggle with Safari but mostly have to code using the .contains(mouse) method while checking that the coordinates have changed to ensure it’s a new touch.
