Hey Reader, I didn't sleep much last night. I was up pushing Sol to fix things that GPT-5.5 couldn't. I got early access to GPT-5.6 yesterday, and I had agents working on both macOS and iOS apps (and QA tooling). These models are super capable, but they have different strengths and weaknesses. I had them work on SwiftUI for an iPhone app today. Watch: GPT-5.6 vs Fable 5: 4 UIs, Judged Blind, 1 Winner Can you tell which model made each UI? Hint: one is not like the others. Now, we have access...

Hey Reader, I rebuilt the onboarding flow for Super Easy Timer, and my downloads started climbing. Three small changes around onboarding, localization, and reviews. Here’s exactly what I did so you can copy it. Downloads trending up with my big 2.0 Update Onboarding My old onboarding showed five videos and didn't give users a chance to try the app. The new flow does one job: show someone how the timer works. One short video, then an interactive timer that they tap through themselves. No...

Hey Reader, Apple just approved Super Easy Timer 2.0 n the Mac App Store! 🎉 If you haven’t been following along, this app has made $7k over it’s lifetime (8 years, but was dying), so I spent the last two months fixing up deprecated code and revamping the UI.

Hey Reader, This week, I tested Fable 5 vs. Codex 5.5 on a real app feature. Now Fable 5 is banned by the US Government. I didn't expect this... Here's a sneak peak of my upcoming model comparison video with Fable 5 and GPT 5.5. Watch: I Fixed My Mac App With Fable 5 Before It Got Banned Fable 5 isn't perfect, but it's the best Claude model I have used. Planning was very detailed UI designs were mostly correct Turns were a little slower on high I would say try it out, but you can't. Sorry!...

Hey Reader, I didn't sleep much this week. Codex was too much fun... just one more prompt... ... then one more ... then it's 1am. You know the feeling. My problem was that I couldn't stop. You might be the opposite: too many app ideas, too many models, and no idea where to start. So pick one thing and push it forward. And if you're overthinking it, this video is for you. Paul Solt @PaulSolt Codex unblocked my app development progress and solved my motivation problem for updating an old, “soon...

Hey Reader, Every indie dev has an app like this: Made some money and then died... Mine made $5K since 2018. Eight years of deprecated code ... I never had energy to touch it. It wasn't worth weeks of cleanup for an app making a few dollars per month. THEN I gave it to Codex. The cleanup was done in 30 minutes. Now I'm shipping the redesign I'd been stuck on for years.
