On the podcast, I talk with Charlie about why Liquid Glass represents a big opportunity for new and existing apps, Apple’s new on-device AI models and their practical limitations, and why the improved App Store Analytics complement rather than replace third-party tools like Appfigures and RevenueCat.

Top Takeaways:

🫧 A style refresh is a growth hack

A major UI overhaul—like Apple’s new “liquid glass” design—creates a once-in-cycle chance to stand out. Apps that ship the new look on day one dominate screenshots, roundup articles, and “App of the Day” slots. It’s free reach: adopt the guidelines early, respect the new hierarchy (avoid stacking glass on glass), and you can siphon users from slower rivals without a bigger ad budget.

🎯 Keywords deserve their own landing pages

You can now pin specific search terms to specific custom product pages. A running-focused page for “5k training,” a cycling page for “bike tracker,” each with its own screenshots and messaging. App Store Connect then breaks analytics down by page, turning guesswork into clear attribution. The result: higher paid-per-download and a shortcut to segment-level A/B testing—no SDK required.

⚡ Tiny, local AI = instant delight

Apple’s on-device foundation models aren’t GPT-4, and that’s fine. Their super-fast, private inference (with a 496-token context window) shines at micro-tasks: sentiment tags, quick text rewrites, lightweight image badges, feature-name suggestions. Treat them as edge helpers, not flagship features. For deep research or long context, hand off to a cloud model. Paired wisely, the mix keeps experiences snappy without sacrificing quality.

🪟 Build like screens will fold

iPadOS 26 finally lets apps run true windows, offload background work, and juggle tasks like a desktop. That’s great for tablets today and a rehearsal for rumored foldables tomorrow. Audit your layouts: do panes resize gracefully? Can a process finish if the user drags your window aside? Investing in this responsiveness now means you’re launch-ready when new form factors arrive.

🔑 Promotions should be measurable

Offer codes used to be subscription-only; now they work for consumables and one-time purchases too. You get up to ten trackable code groups (each with up to a million codes) plus UTM-style links and the expanded App Store analytics to see which podcast promo, TikTok ad, or partner giveaway actually drove revenue. You can finally run seasonal sales or affiliate deals without duct-tape spreadsheets and double down on what moves the needle.
