They Both Die at the End by Adam Silvera

I have really enjoyed everything I have read from Adam Silvera. I liked this book but I did not LOVE it. I listened to it instead of reading it so that could have played into my interest level.

Amazon Summary
On September 5, a little after midnight, Death-Cast calls Mateo Torrez and Rufus Emeterio to give them some bad news: They’re going to die today. Mateo and Rufus are total strangers, but, for different reasons, they’re both looking to make a new friend on their End Day. The good news: There’s an app for that. It’s called the Last Friend, and through it, Rufus and Mateo are about to meet up for one last great adventure—to live a lifetime in a single day.
