Learn to code for free on your phone, in as little as 5 minutes a day with Grasshopper

Learn your first semester of computer science in as little as five minutes a day.

• Fits in your pocket, and your lifestyle. You don’t need a fancy laptop or a lecture hall to write code. You’ve already got a supercomputer in your pocket! So fire up your smartphone, and start coding during that commercial break, or your evening commute.
• Focuses on doing, not just reading. The best way to learn to code is to actually write code. That’s why Grasshopper goes straight to coding real stuff, not watching hours of videos or learning syntax. You’re writing real JavaScript from the very first lesson.
• Finds the approach that fits you best. One size doesn’t fit all. Not when it comes to pants (even the stretchy ones), and definitely not when it comes to coding. So Grasshopper lets you explore different lessons, and provides just-in-time feedback to guide you along the way.
