SoftwareByEugene - Premium iOS Apps for Productivity & Fun

Hi. I'm Eugene.

I'm Eugene Lin. When I was in fifth grade I convinced my parents to buy me an Apple IIc, and I learned to code so I could make games. A bit after that, I spent 20+ years at Microsoft and Meta designing and shipping all kinds of software, from world-class operating systems to game platforms to enterprise-grade productivity tools to billion-user messaging apps.

Now that I've shifted focus to my personal life, I've gotten back to my roots as an indie creator. I make apps for fun. I make apps for my little boy. I make apps for my friends. I make apps because I love it. And I'd love it if you gave any of them a try and let me know what you think.
