## What is ETA321?

ETA321 為香港公共交通而設，將港鐵、城巴及九巴的公開 ETA 資料，轉化為更清晰、更易掌握的分秒預估倒數。見到下一班仲有 7 分鐘，先後悔行慢咗？ETA321 讓你不只看見「7 分鐘」，而是更直觀地掌握剩餘時間，幫助你判斷應否趕車、候車或準備轉乘。

功能包括：
(1) 港鐵分秒 ETA 預估倒數；
(2) 港鐵路線地圖及列車位置推算；
(3) 城巴及九巴路線到站預估；
(4)  iPhone 鎖定畫面及動態島 Live Activity。

ETA321 會以公開資料更新作為參考，提供穩定易讀的倒數體驗。所有到站時間及分秒倒數均屬預估資訊，請以營辦商官方公告及現場資訊為準。
