Made to be tried.
CS42 is a space for designing and testing tools, games and apps. Ideas are built until they work, then put online where anyone can try them.
Most things here start as a question: would this be useful, would it be fun, does it even work? The quickest way to find out is to build a small version and use it.
When something works well enough, it goes online. Some ideas stay small and do one job. Some get dropped, and that is part of it too.
Everything is free to use, there are no ads, and nothing asks you to sign up before you can try it.
How it works.
A few rules that apply to everything here.
Working over perfect
Things go online once they work. How people actually use them decides what changes next.
Free, with no ads
Nothing here carries advertising, and nothing is designed to keep you around longer than you meant to stay.
Private by default
Things run on your own device wherever they can. Data is asked for only when a feature needs it, and the privacy policy says what and why.
Four kinds of things.
Experiments, apps for iPhone, things to play, and a quiet corner.
Experiments
New tools put online to be tested in real use, from the classroom to the well site, while they are still being shaped.
All experimentsiOS apps
Native apps, private by default and happy offline.
All appsPlay
Quick things for a short break: quizzes, games and a piano.
Everything in PlayChill
A quiet corner of the site: a soundscape mixer and a breathing guide.
