Website to iOS App: What's Possible Today (and What's Coming)

Converting a website into an Android app is largely a packaging problem: wrap the site in a WebView shell, sign it, and it's installable. iOS is a different game — not because the technical wrapping is harder, but because Apple's App Store review process is specifically designed to catch and reject apps that are 'just a website in a box.'

The rule that actually matters: Guideline 4.2

App Store Review Guideline 4.2, 'Minimum Functionality,' is the one that trips up most website-to-app conversions on iOS. Apple's reviewers look for an app that behaves like a native iOS app — not a mobile browser with an icon. A bare WebView wrapper with no native navigation, no offline handling, and no iOS-specific touches is a common rejection reason. Apps like Amazon and Basecamp do use WebViews internally, but they pair them with real native functionality — push notifications, native navigation chrome, offline states, system share sheets — rather than shipping the browser experience unchanged.

This is the core reason Android and iOS aren't the same problem: Google Play generally accepts a well-built WebView app on its own terms, while Apple expects meaningfully more before it'll list one.

Option 1: Ship a PWA instead of an App Store app

Since iOS 16.4, Progressive Web Apps added to the Home Screen via Safari's Share → Add to Home Screen can receive real push notifications — no App Store listing required. It's a genuinely useful path if your priority is 'installable with notifications,' not 'discoverable in App Store search.' The tradeoffs: there's no one-tap install banner on iOS (Apple doesn't support it), users have to know to manually add it to their Home Screen, and you get zero App Store discoverability or credibility.

Option 2: A native WebView wrapper, built to pass review

This is a real native iOS app — Swift/native shell, App Store listing, the works — with a WebView loading your site inside it, but built with enough native surface (push notifications, native tab bar, offline fallback) to satisfy Guideline 4.2. It's more work than the Android equivalent because passing review isn't guaranteed on the first submission the way it typically is on Google Play.

Where Capsule stands on iOS today

Capsule ships production-ready Android apps today — signed APK, your own package name, unlimited rebuilds, $120 flat. iOS is on the roadmap, and the reason it isn't live yet is exactly the gap described above: an iOS build worth shipping needs to clear Apple's review bar, not just technically exist. That's a different, more involved build than the Android pipeline, and we'd rather ship it right than ship it early.

What to do in the meantime

1. 1If you need something installable on iOS right now with notifications, a PWA via Add to Home Screen is the fastest legitimate path — no App Store review, works on iOS 16.4+.
2. 2If you specifically need App Store presence now, budget for a native wrapper build that includes real native functionality, not just a WebView — plan for at least one review cycle.
3. 3If Android is your priority platform (or a fine place to start), ship that now for $120 flat, and treat iOS as the next platform once it's available.
