Signal watch

Signal watch is an early heads-up. Every morning it checks five of your signals against your healthy normal, and speaks up when several drift the wrong way at once. You'll find it on the Body tab.

Steps

1. 1Tap BodyBody is the fourth tab in the tab bar, next to the round + button.
2. 2Find Signal watchIt sits under Long-term stress. The pill shows All clear, Watch or Flag, with a one-line summary under the title.
3. 3Read the gridFive signals, one column per morning for the last 14, today on the right. Orange squares are off; the temperature trend line sits underneath.

Step 1 of 3

The five signals

Each one is compared with your last 28 healthy mornings. A signal is off when it's about 1.25 usual swings away in the wrong direction:

All clear, Watch and Flag

The pill at the top of the card gives this morning's status: - All clear: "Nothing is drifting." No more than one signal is off. - Watch: two or more signals are off this morning. "Worth keeping an eye on." - Flag: three or more are off this morning, or two or more were off on 2 of the last 3 mornings with skin temp, breathing rate or blood oxygen among them. "Consider an easy day."

That last rule needs skin temp, breathing rate or blood oxygen because a hard workout can move HRV and resting HR on its own.

Reading the card

• The grid shows the last 14 scored mornings, one column each, with today on the right. An orange square is off, a dark square is normal and a striped square means no data.
• Temperature trend under the grid averages your last 3 nights of skin temp against your normal. If you've run warm 3 nights or more in a row, it says so.
• See temperature trend opens the chart.
• See recent flags lists every Watch and Flag morning from the last 45 days, the signals that drifted on each, and when you were back. A morning after a heavy day is marked, since hard training moves these signals too. It also shows how often Signal watch has fired on your healthy days.

Signal watch is a pattern check for training and wellness, not medical advice. If you feel unwell, talk to a doctor.
