keycat
Get better at frontend in 5 minutes a day.
Keycat is a mobile app that helps you level up your frontend: short daily reps on JavaScript, React and CSS, from the basics to the bugs that only show up in production. We’re building it now.

What Keycat is
Think Duolingo, for frontend.
-
Courses, not videos.
Structured paths through JavaScript, React and CSS, built from small lessons that add up.
-
A lesson fits in a coffee break.
One concept, a few questions, the why. About 5 minutes, on your phone.
-
A streak that keeps you honest.
Come back tomorrow and keep it alive. Small reps, every day, beat the course you never finish.
Why daily reps work
Small, daily and tested beats cramming.
