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…

Very happy to be featured for 4 apps in the Apple Keynote at WWDC 2026 yesterday! #wwdc #wwdc26

Looking forward to speaking at this. It's the Aussie after party for WWDC. Come along, it should be a lot of fun ontour.devworld.au/index.php

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.

Hopefully there’s enough plane fuel for the 21 hour trip! 🛫🍎 #wwdc #wwdc26

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

Looking forward to joining this panel with my good friends @mdelbo and @mattcomi, both brilliant app developers. It should be a fun one. If you’re in Perth and interested in mobile apps, come along. meetup.com/perth-mobile-app-…

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

I'm doing an AMA over on Reddit if anyone is keen to follow along reddit.com/r/SideProject/com…

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…

Thanks Apple Australia for choosing 7 Minute Workout and WordBoard! apps.apple.com/au/story/id18… #iOS26 #appstore

For the last 6 months, I've been working on something so personal I almost don't want to share it... At 41, I was diagnosed with osteoporosis.

Submitted 5 app updated for iOS 26 today. It was a day.

Automated AI PR reviews really are a game changer for indie devs and side projects developers.openai.com/codex/…
