John: It’s hard to understate the importance of the iPad’s large screen. Early critics dismissed the device as a big iPhone, but that criticism revealed a fundamental misunderstanding of the product.

By jumping from the iPhone’s small 3.5-inch display to one that approached 10 inches, the iPad delivered a canvas that allowed Apple and third-party developers to rethink not just the concept of mobile apps, but of apps altogether. The additional screen real estate allowed developers to flatten and spread UIs in a way that made new uses possible. That, in turn, led to richer, deeper experiences for everything from reading a comic book to managing complex projects and automating repetitive tasks, allowing users to interact directly with the software beneath their fingers.

After years of using the very best apps developers have to offer on the iPad, it was remarkably easy for Federico, Ryan, and I to come up with a list of the iPad apps that have been the most impactful for us during the past decade. There’s a lot of factors at play in arriving at these apps. Some forged a path by adopting the latest Apple technologies in a unique way that set an example for apps that followed. Others are apps that define a category that takes unique advantage of the iPad’s hardware. These are also apps that work on the iPhone or Mac too, but are most at home on the iPad’s unique platform.

Although there is no single formula for which iPad apps have been the most impactful, one thing each app in this collection shares is a rich, personal experience. These are apps inspired by and reflected in the image of Steve Jobs sitting onstage in a comfortable black leather chair swiping through photos. The iPad and the apps that run on it have come a long way since then, but the intimacy of directly manipulating apps that transform a slab of glass into anything a developer can imagine hasn’t changed, and remains what makes the iPad so special.
