In a blog post, Instagram discusses how the app takes advantage of the larger iPad screen:

Instagram has always been the place where people connect over creativity, and Reels has become a primary way people discover and share entertaining content. With Instagram for iPad, we’ve redesigned the experience to reflect how people use bigger screens today – for lean back entertainment. Now, when you open the app, you’ll drop into Reels, so you can get the entertaining content you love on a bigger screen. You’ll also see Stories at the top, so you can easily connect with the people that matter to you, and messaging is one tap away.

The iPad version also features a new Following tab. That gives you multiple ways to see the latest from accounts you follow. You can select from All, Friends, or Latest.

The Instagram app is for both the iPhone and iPad and is a free download on the App Store.
