Eclipse Yourself

Readiness is one of the three Eclipse circles along with Activity and Recovery

What is Readiness

Readiness can monitor physical fatigue and mental stress, giving insights on when you are ready to perform, and when you should consider your options. Readiness can even provide warning signs for when you may be getting sick.

Were you refreshed and ready to go when you awoke this morning? Was that workout yesterday too much? Has work been stressful of late? Readiness can assist in providing context to all these sorts of questions plus more.

Tip: tap the middle of the Eclipse anytime to determine your overall health balance across all metrics. Additionally, tap into any of the Activity, Recovery or Readiness gauges for a detailed view.

Readiness Divergence

Eclipse Readiness analyses your waking pulse, heart rate variability (HRV) and wrist temperature. All these measures are part of a weighted algorithm to provide an overall Readiness Rating each day.

When the Readiness circle is in Eclipse (or hidden), you are in balance in your readiness. However, if you see some divergence and the Readiness circle pops out of the Eclipse, you are out of balance (as seen below). This suggests that something is out in your baselines.

How Do I Capture Readiness?

Readiness requires you to track your sleep with your Apple Watch, using the Apple Sleep app or AutoSleep app.

For sleep monitoring, the native Apple Sleep app is available for Apple Watch Series 4 and above, or AutoSleep is available for all Apple Watch series.

Wrist temperature is optional and requires an Apple Watch Ultra or Series 8. Readiness will still work fine with no temperature data.

Refer to Frequently Asked Questions for more information on capturing readiness.

Are you ready for the day ahead?

Every day is different. Understand how prepared your body is to take on the day's challenges.

Readiness is a strong indicator of your physical and mental performance potential for the coming day, as well as giving insight into whether you have been pushing things too hard.

Readiness Sunrise

When the yellow sun is above the horizon, your readiness is in balance. The higher the sun rises in the sky, the better prepared your body is to take on the day.

Today's Readiness Sunrise is displayed after each sleep on the home page and readiness page, providing instant insights when needed in the morning.ย 

Each of the metrics are plotted above or below the horizon to show their impact on your readiness. The sun reflects your overall readiness rating based on an advanced weighted algorithm.

Tip: tap the 'Learn More' button under the Sunrise graphic to see a detailed breakup and explanation of your readiness metrics.

Readiness Gauge

The gauges are a reflection of your Eclipse circles, consisting of Activity, Recovery and Readiness.ย 

Each gauge is tailored to your health history. The white needle is your current measure against your longer term baselines, so if the white needle is pointing far to the left on the gauge, your Eclipse will be out of balance.

Tip: the outer line colour of the gauge reflects the same as the Eclipse circles.

Readiness - In Balance

Anytime the white needle is in the top centre and right segments (see the below image between the yellow arrows), this indicates your Readiness is in balance, meaning your Readiness circle will be in Eclipse.

Readiness - Out of Balance

Anytime the white needle is in the far left segments (see the below image between the yellow arrows), this indicates your Readiness is out of balance, meaning your Readiness circle will not be in Eclipse.

If the white needle is far to the left, you are out of balance in your readiness, which means you may need to look into what is contributing such as fatigue or stress. If the needle is too the far right, that is absolutely fine as it means you are getting maximum readiness.

The aim is to keep the Readiness white needle on the gauge in the top and right segments.

Tip: tap the Readiness gauge to open the trends view.

Readiness Trends

When you tap on the Readiness gauge, you will open the the Readiness Trends screen. Here you can see your readiness trends from the current day to the last 6 months.ย 

Each day is visually represented as a bar with a sun rising above or below the horizon to indicate your overall readiness rating. ย The higher the little yellow sun shows on each bar, the better your readiness for that day.

Stay Above The Horizon

Each of your key readiness metrics are plotted above or below the horizon. The horizon is your par, which is personalised to your longer term baselines over 6 months of collected health data.

Eclipse Readiness combines all the key metrics using a weighted algorithm to show if your readiness is above or below par for each day. Each metric impacts the overall recovery rating, which is shown as a white line with a yellow sun.

Staying above the horizon (or par) keeps your Eclipse Readiness in balance.

Tip: You can swipe left and right across the Readiness graph to see up to 6 months of data. The colours let you easily identify what contributes to good readiness and what may be causing poor readiness.

Make sure your body is adapting.

Readiness is linked to your autonomic nervous system (ANS), as this controls your HRV.

Your overall readiness rating gives insights into how your body is coping with daily life, including work, training, diet, stress, illness and more.

Readiness Metrics

Individual metrics each contribute towards your readiness.

Each metric is tailored to your baselines, which is calculated by looking at the last 6 months worth of data. So it's safe to say that Eclipse understands when things are better or worse comparing to a 6 month baseline.

Each readiness metric acts a like seperate block that builds or removes to your overall rating based on the variance to your baseline. They can each add positively, neutral or negatively to your readiness.

Tip: readiness metrics come from your sleep session, so you need to be tracking sleep with the Apple Sleep app or AutoSleep app to see the insights.


The overall rating is calculated from combining all the readiness metrics with the Eclipse algorithm. The rating can be seen on the graph as the white line with a yellow sun dot. The overall readiness rating is made up from 3 key metrics: BPM, HRV and Temperature. Each are detailed below.


This is your waking pulse and is measured in beats per minute (BPM). Your heart rate can change over the course of a night, however your waking pulse is considered one of the gold standards when measuring your resting heart rate. This makes it a critical metric as part of your overall readiness.

Studies have found that your waking pulse is a strong predictor of cardiovascular health. Pay attention to different factors that may influence your measurement such as activity, mood, food or alcohol.

This is automatically captured when you start to wake from sleep when using the AutoSleep app or Apple Sleep app.


Heart Rate Variability (HRV) is a method for assessing the effects of stress on your body, by measuring the variances between your heart beats. HRV is reported in milliseconds.ย 

Eclipse Yourself will determine your baseline HRV measurement for Sleeping and Waking periods. Generally speaking, if your HRV reading is above your baseline it means you are less stressed. If below the baseline it means you are likely more stressed.

The value comes from comparing your day to day changes against your baseline. There is no point in comparing your HRV reading with someone else. There's also no point in comparing the readings to those taken at other times during the day. It means next to nothing. The value comes over time.

Eclipse lets you choose which HRV option is best for you in the 'Configure my Eclipse' setup (found in the Options tab), with an option to use Waking HRV or Sleeping HRV. Sleeping HRV is the default setting for new users.

Waking HRV - will use the closest HRV measurement from your waking sleep window, however it is best measured by activating a breathe session on your Apple Watch on wake up, as this creates a wake up protocol. The breathe session is found in the Mindfulness app on your Apple Watch.

Sleeping HRV - will use the average across all automated HRV measures during the sleep session. The number of measures is controlled by the Apple Watch.

Refer to the 'Configure Readiness Settings' section below for more information setting up.

As a side note, we have noticed that if you turn on the Atrial Fibrillation (AFib) on the Apple Watch, this will significantly increase the total HRV measures over the sleep session and waking window. Please refer to the Apple Support Site for more information on using AFib, as it will depend on your personal medical history.


Your bodyโ€™s a bit like a little oven that is always on. It generates heat to keep you alive. However there is a typical normal temperature range to be in, so when it is a lot higher or a lot less, itโ€™s trying to tell you thereโ€™s a problem. This is where Eclipse Readiness will monitor variances against your temperature baseline.

Temperature is only available for users with an Apple Watch Series 8 or Ultra. If you are on an older Apple Watch, it will be blank, but this will not influence the overall readiness rating. If you do capture wrist temperature, it will be automatically measured while you sleep.ย 

Normal or High Sensitive Temperature - we understand that some users are more sensitive to temperature changes. Eclipse Yourself lets you configure the temperature fluctuation sensitivity, with an option to use Normal or High Sensitive. Refer to the 'Configure my Eclipse' section in the Options tab to set. Normal is the default setting for new users.

Refer to the 'Configure Readiness Settings' section below for more information setting up.

Tip: If you are using Waking HRV, there's a surprisingly easy and pleasant way to capture HRV. Upon waking, do a 1 minute session using the Breathe app on your Apple Watch. This is found in the Mindfulness app on your Apple Watch.

When capturing HRV consistency is everything. When you wake, don't do any vigorous movement, just start the Breathe app session whilst lying down, close your eyes and relax. Don't move. Not only does this ensure maximal consistency of measurement, but it's also a nice way to start the day.

Viewing Individual Metrics

You can filter on individual metrics in Readiness and Recovery. This is great if you are focused on monitoring a specific metric.

Just touch the one that you want to view, such as heart rate variability (HRV), and the graph will adjust to show just that metric (see below image). You can also use the 7D Trend gauge to apply a rolling 7 day average to just that metric.ย 

To turn off the filter, just touch the same metric again.

Tip: On the Eclipse home page, you can also touch the individual readiness metric and it will automatically filter on this when loading the next screen.

Readiness Mini-Gauges

At the bottom of the screen in the pop-up panel is a selection of small gauges, named the 'READINESS' gauge and '7D TREND' gauge. Tap on any of these mini-gauges and the entire Readiness graph and views will all update with that selected metric as the focal point.

The '7D Trend' gauge allows you to visualise small changes more easily over a longer period.

In this example, I have started meditating more in the evening before bed. Visualising the changes with the 7 day rolling averages is much more effective.

Tip: you can touch and pull-up the mini-gauge panel to see more helpful information about what each does.

Configure Readiness Settings

Before you start, to get the most accurate results you can configure the Readiness settings in Eclipse. On the home screen, tap on the Options tab and select the 'Configure my Eclipse' button.

Scroll down to the Readiness menu and will see the configuration options available:

Heart Rate Variability (HRV) Configure:

HRV is a measure of the variation in time between each heartbeat. You will need to use either the Apple Sleep app or AutoSleep app to track your HRV while you sleep.ย 

Eclipse lets you select between your Sleeping HRV or Waking HRV to use as part of the Readiness algorithm. Both are fantastic measures.

If you select Waking HRV, it will use the HRV measure in the waking window that is recorded by the sleep app. However, as automated HRV measures are controlled by the Watch, not the app, you may see cases where no waking HRV was automatically recorded. For this, we recommend if set to Waking HRV, that using the breathe app (found in the Mindfulness app) on your Apple Watch on wake up is recommended for best results.

Use the + and - buttons to change. Remember to select 'Done' to save your changes.

HRV Waking Window:

For any users set to Waking HRV for Readiness, you have the option of using a 60 minute waking window or 15 minute waking window. By default 60 minutes is set, but 15 minutes is helpful for users who may want to use the best HRV measure closest to their waking state.

The reason that Eclipse uses a time period before waking, is that the Apple Watch may not automatically capture a HRV measure in this time period. We see this even for users who take a breathe session. This period acts as a safety net.

If using the 15 minute setting, we strongly encourage to set the Watch to use Afib History to increase the HRV samples taken, or use the mindfulness app on wake up to record a breathe session.

Temperature Sensitivity Configure:

For users with an Apple Watch Series 8 or Ultra, you can measure your wrist temperature while you sleep. As some users are more sensitive to temperature fluctuations, Eclipse has the option of Normal or High Sensitivity.ย 

Normal is fluctuation between 0.5 degree celsius. Sensitive is fluctuations between 0.25 degree celsius. Both will capture signs of illness as it is usually above fluctuations of 1 degree celsius (1.8 degrees F).

Use the + and - buttons to change. Remember to select 'Done' to save your changes.

Tip: in order to collect readiness metrics like wrist temperature, enable the Sleep Focus mode on your Apple Watch at bedtime (see below). This is an Apple Health requirement. It also puts your Watch into 'do not disturb' so it doesn't wake you up! See the below image showing the Sleep Focus icon.
