13 Year Old Has Developed Almost 20 WP7 Apps

It seems for at least some of the 18,000 apps in Marketplace we have the productivity of a 13 year old to blame, with 13 year old Johnny Simmons of Simzz Dev having nearly 19 apps in Marketplace.

Johnny learned by watching videos and finding code samples, and in the above video tells SV Architect Evangelist Bruce Kyle about how he got started, and how he makes money through AdCenter.

Johnny’s apps include:

  • DrawPad
  • DrawPad Pro
  • NightClock
  • Analog Night Clock
  • Random Numbers and Dice
  • 7 Tab Browser Free
  • 7 Tab Browser Pro
  • Chasing Howie
  • NBA Schedule
  • System Info

He notes that he makes his best revenue from his ad-supported applications. I dont recall much of what I did age 13, but I am sure running a software business was not one of them.
