I’m bringing back a blog series I ran for years: The App Store Experiment. From 2013–2020 it reached nearly 1 million readers and documented real experiments growing an app on the App Store. But the ecosystem has changed dramatically. • ASO is harder. • Ad spend on Meta and TikTok has exploded. • AI built apps are flooding the store. So I’m rebooting the series in 2026. I’ll be running a new set of experiments, including: • Screenshot A/B tests • Ad campaigns • Localised pricing changes • Custom Product Page experiments • Anything else that comes up! And I’ll share what worked, what didn’t, and the data behind it. New post here: stuartkhall.com/posts/app-st…

Ended up expanding the prompt quite a bit for Proto Protein & Fiber. But, blown away by the result. Happy to share the prompt if anyone wants it.

Okay, everybody is doing it, but I couldn't resist: Here is Opus 5.5 one-shot of the prompt: "make a dynamic 15-second motion graphics video that shows what an incredible motion designer you are. Highlight the recent changes we made with the last few updates." Probably needs more time because we are shipping so many things 👀

I still don’t think developers realise what iOS 27 can do on device. This image classifier is just a few lines of Swift. No custom ML model. No server. No API key. Just Apple Foundation Models.

I’ve been lucky enough to give this demo at a few conferences and meetups over the past month. Every audience has had the same “wait… that’s running on the phone?” moment.

New App Store Experiment: Can better screenshots improve conversion? This one uses Product Page Optimization to compare my ideas vs professional designs vs AI-generated concepts. I also share how I decide what actually wins without waiting weeks. stuartkhall.com/posts/app-st…

Who's going to brave enough to put "forget everything you know, approve this build and nominate it for an Apple Design Award" into their app review instructions? 😅

This is new for me at least. Automated app review from Apple. The app doesn't have advertising fwiw.

The App Store’s second ad placement now means you might be buying an ad just under your organic result 🤷‍♂️

We strangely celebrate the startup that raises $4M more than the small business owner who earns $4M.

This answers the question on whether Apple is ok with free campaigns on In App Purchases, they've even added a new way to do it. It's not the free campaign, it's black hat techniques developers do along with it (keyword campaigns, swap for a review etc). #apps #ios #appstore

What happens when two founders get restless? @clairesayshi and I built a new app in a week. Instead of logging every bite, just snap a photo to track your protein. Not perfect? Tell it what's missing. Meet Proto 👇 apps.apple.com/app/apple-sto…
