Apple introduced Live Activities almost three years ago, in October 2022, and since then, it’s become one of my favorite iPhone features.
For those not up to speed, Live Activities is a feature that provides you with access to real-time information directly useful to you, right from your Lock Screen. No need to unlock your iPhone or open an app.
When you are using your iPhone, these Live Activities can be seen in your iPhone’s Dynamic Island (should you have a newer iPhone), too.

I primarily use Live Activities with Apple’s Sports app to keep track of Yankees and Devils games when I’m away from home. (Fun fact: these updates are often so quick, I’ll get a score update before the action happens on the TV, which is cool but also a bit annoying.) I also use it every day when listening to Spotify to control music playback.
But Live Activities has a ton of other use cases and works with numerous third-party apps. Most commonly, ride-sharing and food delivery apps, like Uber and Uber Eats, support Live Activities, so you have easy access to real-time progress updates for orders.
That said, when iOS 26 is released in the coming days, Apple is making Live Activities even more useful and versatile than ever.
