Josuam Collazo

Independent iOS developer, and the person behind everything published here.

I have loved technology since I was a kid. I am in my mid-thirties now, and I spend my free time building useful, helpful apps drawn from my own experiences, both past and present, as I keep growing in my professional career. The writing here comes from the same place: things I had to figure out for myself, explained the way I wish someone had explained them to me.

I write about consumer tech and gadgets, on-device AI, long-term investing, digital privacy, and your rights at work. I try to keep it plain, honest, and free of hype. When a piece touches money or health, I keep it to general information and point you to a professional for decisions about your own situation, because that is the responsible thing to do.

On the apps side, I run JC Mobile App Studio, a one-person iOS studio. The apps are built to run on-device wherever possible, with no ad tracking inside them. You can browse the apps here, or read the full blog archive.
