todayOS 是一款給想同時照顧多種健康目標、又不想追連勝或解讀整面圖表的人使用的 Apple 平台 app。它依據使用者授權的 Apple 健康資料、作息、天氣、使用 Mac 的時間與偏好，從喝水、起身、散步、曬太陽、休息眼睛、呼吸與睡前準備等行動中，選出當下最值得做的一件事。
多數健康 app 讓使用者面對更多資料：步數、飲水、久坐、運動、日照與睡眠分散在不同畫面，卻沒有回答「現在先做什麼」。todayOS 的出發點，是把這些訊號收斂成一個當下的行動提醒。
todayOS 只使用使用者明確授權的 Apple 健康資料，並把這些資料與作息、天氣、使用 Mac 的時間及偏好一起納入判斷。主畫面同時保留今天仍值得注意的事實進度，但不以連勝、歷史報表或目標壓力驅動使用者。
同一份推薦結果會延伸到 iPhone、小工具、Apple Watch 與 Mac，讓使用者不必打開完整 app 才知道下一步。todayOS 不是醫療器材、診斷工具或治療計畫。
todayOS is an Apple-platform app for people who want to care for several health goals without streak pressure or a wall of charts. Using authorized Apple Health data, routine timing, weather, Mac usage, and personal preferences, it surfaces one useful next action, such as drinking water, standing, walking, getting daylight, resting your eyes, breathing, or winding down.
Most health apps put more data in front of people: steps, hydration, sedentary time, exercise, daylight, and sleep live on separate screens, but none answers “What should I do first right now?” todayOS starts by reducing those signals to one action reminder for the current moment.
todayOS uses only the Apple Health data the user explicitly authorizes and considers it together with routine timing, weather, Mac usage, and personal preferences. The Today view keeps factual progress that still matters visible, without using streaks, historical dashboards, or goal pressure to drive behavior.
The same recommendation extends to iPhone, widgets, Apple Watch, and Mac, so users can see the next action without opening the full app. todayOS is not a medical device, diagnostic tool, or treatment plan.
