Built life-admin software solo, on a phone, with AI — anyone else going unconventional?

I've spent the last few weeks building an app called Actually Done — basically a home for all the scattered life-admin stuff (documents, passwords, medical info, reminders, bills) that normally lives across six apps and a shoebox.

The part I keep thinking about: I built the whole thing on my Android phone, using Replit's AI agent, with no formal coding background. No laptop, no IDE — just a phone and a lot of back-and-forth with an AI pair programmer. It's been a strange way to learn software development in real time — the agent writes the code, I do the actual QA (I don't trust "it's fixed" without proof), and I make the product calls.

I'm veteran-owned, so a lot of what I'm building comes from wanting things to just be organized and findable when it actually matters — not just neat.

Launching on Product Hunt in a few days. Before that, I'm curious about this community:

Has anyone else built something meaningful without the "normal" setup — no dev background, no desktop, no team? What was the hardest part of trusting the process?
