Hey Reader,

My workflow with GPT-5.5 is completely different from GPT-5.4 — and this changed over the weekend.

With GPT-5.4, I revived my 9-year-old Super Easy Timer app and pushed conversion from 0.5% to 7.1% over the past two weeks. This week, I had early access to GPT-5.5 and it unblocked my deprecated macOS dependencies in one shot.

I wrote up exactly how I'm using the Codex app + GPT-5.5 to build iPhone and Mac apps faster — and how I'm using App Store reviews to write copy that actually converts into downloads.

Read it now: How I Build Apps with the Codex App and GPT-5.5​

Inside the article:

• Drive Codex in real time without plans.
• Stop agents from reporting fake Xcode build success.
• Use App Store reviews to write copy that converts.

5 Tools and Resources

1. ​GPT 5.5 launched this week and OpenAI dropped GPT Image 2.
2. ​Antoine has new CLI tools for the iOS Simulator. Faster interactions with the simulator are always good.
3. See how the new GPT Image 2 model compares to Nano Banana and Grok. We both had early access to GPT Image 2, and he shows the good and the bad.
4. Codex is evolving fast. If you feel behind, watch Riley's video: The Codex Super-App (Full Beginners Guide).
5. Want to make money from your apps? Follow Viktor's proven method. He's making $60k per month.

Don't know how to do something? Ask Codex.

Quick Question

Want a free teardown of your app?

I did a public teardown last week on X — it helps to have someone else look at your app from a different perspective. Reply with your App Store link.

P.S. The CLI tools I built for App Store research are free — grab them here​. Use them with Codex to pull customer language straight into your App Store description and screenshot copy.
