Google introduced a feature called app pairs with Android 15, allowing users to save two apps as a single icon for simultaneous launching in split-screen mode. Initially available only on tablets, it expanded to devices like the Pixel 9 Pro Fold and other smartphones. Early users found the multi-window mode cumbersome due to limited display space. Android 16 improved this with a 90:10 split-screen mode, prioritizing one app while minimizing the other, enhancing multitasking on smaller displays. The ability to save app pairs streamlines launching two apps side-by-side. Users have found productivity benefits by pairing apps like Spotify with fitness trackers or productivity tools like Slack and Asana.
