What is the Timeline

The Timeline shows how your data changes throughout the day and over time. It helps you understand patterns in your body’s responses by displaying your physiological data alongside logged activities, sleep, and check-ins.

How to navigate the Timeline screen

To access the Timeline, open the NOWATCH app and tap Timeline (the second tab at the bottom of the screen).

Each metric is displayed as a separate graph. Use the icons below (lightning, heart, steps, and motion) to switch between them.

Explore key metrics

Reactivity Monitor (lightning icon)

Shows how reactive your body is over time, including balanced states, physical activity, recovery, stress responses, and lower or higher reactivity periods.

Heart Rate (heart icon)

Displays your heart rate in beats per minute across the day and over longer periods.

Helpful icons and features

Date colors

At the top of the screen, dates may appear color-coded based on your response to the daily “How was your day?” question, reflecting how you felt that day.

Info (i) icon

Each metric includes an info (i) icon. Tap it to learn what the metric represents and how to read the graph.

3H / 12H view

Use the 3-hour (3H) or 12-hour (12H) buttons to switch between shorter or longer time windows.

Logged events

Icons at the top of each graph show what you logged:

• Moon: Sleep

• Human or objects: Activities

• Bubble: Check-ins

These icons help you connect your experiences with your physiological data.

Walking, cycling, and running are automatically detected. Other activities must be logged manually. Automatically detected sleep or activities appear as white icons without fill. 

Add entries with the “+” icon

Hover over a specific moment on any graph to reveal the “+” icon, which lets you log:
