AI tools are significantly lowering the barriers of app development. I spend most of my working time on web apps, but AI has given me enough of a boost that I’m starting to get a portfolio of mobile apps off the ground too.

Each of these is progressively more useful than the last.

I’ve been getting into breathwork lately, and I wanted to put my own spin on some of the more popular breathwork apps. I built and shipped Breathify, faster than any mobile app I’ve ever shipped.

The app is minimal, with the intent of being maximally calming. It has a great onboarding, a couple core features, and customizable haptics.

If you want to see how I built it, there were a few newsletter editions that went out while I was building it:
