A decade ago, Apple opened a store peddling iPhone apps, unlocking the creativity of software developers and letting users truly make their mobile devices their own.
The resulting explosion of phone apps — there are now more than 2 million for the iPhone alone — has changed daily life for billions of people around the world.
It has unleashed new ways for us to work and play — and to become so distracted that we sometimes forget to look up from our screens. It has created new industries — think ride-hailing services like Uber, which would be unimaginable without mobile apps — and pumped up demand for software developers and coding schools.
But it has also opened the door to an age of technology anxiety, rife with concerns that apps are serving us a little too well and holding our attention whether we want them to or not.
