Two-thirds of the store is phone-first

Only 38.9% of apps present themselves for iPad at all; the other 61.1% either run as a blown-up iPhone app or skip the platform entirely. That is a striking number for a device this old and this popular, and it reflects a hard economic reality: building and testing a genuinely good iPad layout is extra work, and for most developers the iPhone is where nearly all the users are. The tablet gets the effort only when the app is a natural fit for a large screen.

The iPad is a reading and working device

Look at which categories actually design for iPad and a clear personality emerges. The most iPad-ready categories are led by News (54.6%), Books (54.4%), and Education (50.5%) — the reading, reference, and study apps. This is the iPad people actually own: a couch device for long-form reading, textbooks, news, and note-taking, where the extra screen is the entire point.

What stays on the phone

At the bottom sit the categories built around being in your pocket and on the move. Social Networking (just 26.5% iPad-ready), Shopping, and Graphics & Design are overwhelmingly phone-first — apps you reach for standing in a queue, walking, or paying at a till, where a tablet makes little sense. The divide is not about developer laziness so much as context of use: some things you do sitting down with two hands, and some you do one-handed on the go.

The bottom line

If you use an iPad as your main device, check for iPad screenshots before you download — an app without them may technically run, but it often will not use the screen well. And the pattern is a useful lens on the tablet itself: after fifteen years, the market has quietly decided the iPad is mainly for reading, learning, and creating, not for the quick, on-the-move tasks that keep the iPhone in your hand.
