Out of time!

Do you really think would use that crappy thing? We award you 0 Stars!

We really think would love this thing! We award you 3 stars!

Designer, challenge thyself

Just 15 Minutes a day gives you:

  • Better design thinking
  • Faster design decisions
  • More dates with attractive people
  • Mastery of the whiteboard
  • Dynamite interview skills
  • Happiness and success in all your endeavors

Works best with a friend and a whiteboard, but you can designercize on a screen too. Keep challenges short enough to complete over your lunch break. Do one every day for best results.

Here's an instruction manual (v: @teachang + @_echoi_), based on the original instruction manual (v: @mollyinglish).

Origin story

Designercize is a digital version of an analog whiteboard exercise originally created by Kate Rutter and Laura Klein to help designers improve whiteboarding, interviewing, and design thinking skills. It's been honed over thousands of practice sessions with Tradecraft designers.


The designercize app was created by Tradecraft design instructors Zac & Jake, because we <3 you. Bespoke fonts, handcrafted by Jake, are obtainable here.

Zac Halbert

"All that to say, this is bad."

Jake Fleming

"Uh, no. Bad. Bad design."

Special thanks
