With Android 15, Google introduced app pairs, or the ability to save two apps together as one icon, and launch them at the same time in split-screen mode. The feature was limited to tablets at first, but it soon expanded to the Pixel 9 Pro Fold and other phones.
Initially, I thought I would use this all the time, but I soon realized that the issue was with the multi-window mode itself, and how it displayed a tiny part of both apps and made using either of them clunkier. So I forgot about app pairs for a while, until Android 16 came along, and with it, a significant improvement to multi-window and split-screen multitasking on Android.
