It sounds like a small housekeeping decision, but it signals something bigger: Apple is treating its software ecosystem as one unified thing rather than a collection of separate products that happen to share a logo.
iOS 26 is now on its fourth point update, iOS 26.4 dropped in March, and iOS 27 is already being shaped in Cupertino ahead of the iPhone 18 launch in September. The pace is relentless. And the App Store sitting underneath all of this is changing just as fast, in ways that matter for every app you use.
Liquid Glass Changed the Rules for Every App Developer
The biggest thing about iOS 26 is not any single feature. It is the Liquid Glass redesign, the most significant visual overhaul since iOS 7 back in 2013. Translucent surfaces, light refracting through interface elements, a whole new material language that Apple is calling the foundation of the next decade of iOS design. If you have updated and noticed that everything looks a bit different, that is why.
The practical effect for app developers is significant. From April 2026, new App Store submissions have to be built with the iOS 26 SDK. Every app you download going forward has been built against the new design language. Apps that are invested in proper UI work look noticeably better.
Apps that have been sitting on autopilot are starting to show their age. The divide between apps that care about craft and those that do not has rarely been more visible.
Apple Made This the Biggest Design Shift in Over a Decade
Apple does not usually describe its own software updates in superlatives, which is what makes the language around iOS 26 worth paying attention to. When the company announced Liquid Glass at WWDC 2025, Alan Dye, Apple’s VP of Human Interface Design, described it as a new design that makes apps more expressive and delightful, with Liquid Glass as the material that will underpin the next decade of how iPhones look and behave.
That is a significant claim from a company that tends toward understatement. The fact that Liquid Glass is now mandatory for new App Store submissions from April 2026 tells you they mean it.
Not everyone has been happy about it. Some developers pushed back on the visual changes, and Apple’s response according to reports from a design workshop at its New York offices was apparently one of genuine surprise. The company has made it clear that Liquid Glass is not going anywhere, and that iOS 27 will extend it further. If you are still running iOS 18 and wondering whether to upgrade, the answer is increasingly yes.
The Apps That Benefit Most From a Bigger Screen
The categories that have gained the most from iOS maturing over the past few years are the ones where you are doing something live. Streaming, sport, live betting, finance. These are the apps where performance, speed, and interface clarity matter because you are using them in real time while something is happening.
Betting apps are a good example of a category that has genuinely raised its game. A few years ago most of them were functional but rough. Now the better ones have proper live in-play markets, fast cashout, and the kind of interface polish that sits comfortably on an iPhone screen.
Liquid Glass only raises that bar further, because an app that looked average before is going to look noticeably worse against one that has been built properly for iOS 26. If you follow sport and you have not revisited which betting app you are using recently, it is worth doing.
A solid way to sense-check that is by looking at how the current prime betting apps are reviewed side by side, especially around things like live market speed, cashout reliability, and how clean the interface feels during in-play use. The gap between the top tier and everything else is much clearer now than it was a few years ago.
Siri Is Still the Weak Spot and Apple Knows It
iOS 26 arrived with a lot of promises about Apple Intelligence that have been quietly shuffled into the future. The more conversational, context-aware Siri that was supposed to show up in early 2026 has been pushed back, probably into iOS 27. What you have right now is a version of Siri that is better than it was but still nowhere near what Apple has been describing in its marketing.
iOS 26.5 is currently in beta and there is speculation about whether it delivers on any of those Siri promises or whether the significant changes are being held back for the September announcement. Apple’s track record of making bold AI promises and then delivering them on a different timeline to the one advertised is by now well established, so tempered expectations seem reasonable.
iOS 27 Is Already Being Built Around a Foldable iPhone
The next big jump is coming in September and the context is the foldable iPhone that Apple is reportedly planning alongside the iPhone 18. iOS 27 is being designed specifically around that form factor, which means the software has to handle a genuinely different kind of screen in a way none of Apple’s previous OS updates have had to.
That is a significant design challenge and it will have knock-on effects for the whole App Store. Developers will have another device type to support, another set of interface guidelines to work within, and another reason to update apps that have been sitting untouched for a couple of years.
