Designer & developer making small, useful software.

I'm Steve Zeidner, and I've spent two decades building mobile and web software — from agencies and product teams to my own studio, Tinybits. These days I'm focused on building tools and games I care about.

I'm a builder. My favorite thing is making mobile apps that are both fun and useful — the kind people actually keep on their home screen.

I've shipped software across native iOS and Android, Flutter, React Native, and the web — for agencies, product teams, and my own clients. I led Android at Zero, the intermittent-fasting app used by millions, ran mobile teams at WillowTree (formerly Dynamit) and IBM iX (formerly Resource), and have run my own studio, Tinybits, since 2018.

Lately, the work closest to my heart is my own: Wave, a readiness tool for serious athletes, and Fourshadow, an atmospheric almanac for the year around you — plus small games for Panic's Playdate. I also founded Castle, a podcast player that writes its own transcripts.

Away from the screen, my family and I run Fox Hollow Ranch, an artist's retreat in the Hocking Hills. And when I'm not building, I'm usually out for a run — I still race marathons and ultras, and I love that the long miles give me time to think.
