I'd been using the Codex Mac app for side projects and it was absurdly good. GPT-5.3 on medium thinking was solving things I expected to take hours. But the Mac was on my desk. And I wasn't always at my desk.
The pattern kept repeating: I'd think of a fix while making coffee, or want to check a build while waiting in line. By the time I got back to the Mac, the momentum was gone. I had 10 projects — a stocks app, a video frame extractor, a music app, a pixel art game — and they were all stuck whenever I walked away.
So one night I asked Codex a question: can you build me an iPhone app that talks back to you?
The Codex Mac app has something called app-server — the same protocol surface that powers the VS Code extension. Threads, turns, approvals, streaming output, all exposed over WebSocket. If VS Code can talk to it, an iPhone app can too.
That night, I used the Codex Mac app to build a Codex iPhone app. The tool built its own remote control.
I can finally build features for 10 apps at a time while on a 🚽 — directly from my phone — while it gets built on my Mac mini.
The first time I sent a prompt from my phone, watched Codex stream its response live, saw it build the app, and then installed the finished build back on the same phone I was holding — that was the moment. No cables. No Xcode Play button. Just a tap on "Install" and the app appeared on my home screen.
Now every gap in my day — waiting for coffee, sitting in a car, five minutes between meetings — is enough to review a thread, dictate a change, approve an action, and test the result. I went from shipping a couple of side-project builds per week to shipping something almost every day.
Not because I code more. Because I never have to wait until I'm at my desk.
The system now has its own canonical architecture reference, a runbook of every failure and fix, an operational checklist, and a release automation roadmap. It's not a hack anymore — it's infrastructure I rely on every day.
Fun fact — the OpenClaw founder recently shipped a fix for one of the complaints on Twitter for OpenClaw while he was at the barbershop. I think this will become normal soon.
