Hi, I’m Tom. I build apps and write about how they’re made.

By day I’m a Staff Full Stack Engineer at Deque Systems. On the side I make small apps, like Seaglass and Back & Forth.

Now building

Seaglass

A calm, private sober day counter for iOS and Android. See how long you’ve been free of smoking, drinking or anything else, and the money you’ve kept, and collect a piece of sea glass for every milestone. No account, and everything stays on your phone.
