From first serve to final point — on the Lock Screen.
Every match the user has a stake in surfaces on the Lock Screen and Dynamic Island the moment it goes live. Set scores, the current game, and who's serving update in real time — even with the app closed. When the match ends, the activity flips to a points-earned celebration and dismisses an hour later. Tapping deep-links into the user's relevant league.
"Why this pick?" — generated entirely on-device.
Tap any pick recommendation and a personalized rationale appears in seconds. The model considers recent form on the surface, head-to-head history, serve and break-point stats, and last year's result at the same tournament — all synthesized on the iPhone itself.
Built around the tennis calendar.
Every platform feature draws on tournament-specific data — surface, head-to-head, last year's result at this same event. In-app events tied to each Slam open Tweener's biggest user moments of the year.
