Sleep
Sleep timing and duration are summarized as a recovery rhythm, not a diagnosis.
7-Day Life Report
Patterns beat single days. 七天，比一天更接近真实。
Entropy summarizes sleep, food, movement, and stress signals into a weekly report you can share. The link on every card sends people here first, so they can try the free calculator before downloading the app. Entropy 将睡眠、饮食、运动与压力整理成可分享的 7 日报告。每张图都带短链接，别人无需下载 App，可以先体验免费计算器。
What the card means
Four signals, one weekly view.
A single meal or bad night can be noisy. A seven-day window makes the pattern easier to inspect. 单次饮食或睡眠很容易有噪声，七天窗口更适合观察模式。
Food
Meals, nutrition gaps, and fasting context are grouped into a food pattern.
Movement
Exercise and sitting time are considered together, because both affect the day.
Stress
Mood and social connection signals help explain whether the week had a buffer or strain.
Start without friction
Try one day first, then build a seven-day ledger.
The free calculator gives a rough one-day estimate in the browser. Entropy turns repeated daily records into weekly patterns only after there is enough context. 免费计算器先给出浏览器内的一日粗略估算。真正的 7 日模式，需要连续记录形成上下文。
