General FAQs

Why is there no data in my PeakWatch?

PeakWatch uses health data from Apple Health for analysis. If there is no data in PeakWatch, please follow these steps:

  1. Ensure that you have granted PeakWatch access to health data. Open the Apple Health app, tap the profile icon in the top right corner, go to "Privacy" -> "Apps", find PeakWatch, and make sure all data permissions are "enabled". Then, close and reopen PeakWatch;
  2. Check if there are relevant records in the native Apple Health and Fitness apps. If there is no data in these apps, PeakWatch will not be able to retrieve it;
  3. If the data in Apple Health/Fitness is complete, try closing and reopening PeakWatch to refresh and check if the data syncs successfully. The synchronization process might have some delay, so try a few times;
  4. If, after following these steps, there is still no data in PeakWatch, please go to "Settings" -> "Contact Us" and provide feedback to get assistance.

Why are there two duplicate entries for the same workout?

  • Check if you used a third-party app to record the workout at the same time. Using both a third-party app and the Apple Watch might result in two entries being written to Apple Health;
  • If you don't want duplicate data, you can delete one of the entries in the Apple Fitness app.

Why is there a discrepancy between the watch face data and the mobile app data?

The timing and frequency of updates for complications on the watch face are controlled by Apple's watchOS, which may result in delays. To view the latest data:

  • Manually open the PeakWatch app on the Apple Watch and refresh it;
  • Ensure that both your phone and watch are connected, and open PeakWatch on both devices to sync data.

How can I report a bug?

If you encounter a bug or other issues, you can report it via "Settings" -> "Contact Us".

Please provide the following information to help us investigate:

  1. PeakWatch version number (found in "Settings" -> "About PeakWatch");
  2. Phone model, iOS version (found in iPhone's "Settings" -> "General" -> "About");
  3. Watch model, watchOS version (found in the Apple Watch's "Settings" -> "General" -> "About");
  4. Screenshots or videos of the issue along with a description of the circumstances when the problem occurred.

Sleep

How do I view the source of my sleep data?

You can check the data source and priority in PeakWatch under "Settings" -> "Sleep" -> "Sleep Data Source".

Why don't I have detailed sleep data?

  1. Ensure that you have granted PeakWatch access to health data. Open the Apple Health app, tap the profile icon in the top right corner, go to "Privacy" -> "Apps", find PeakWatch, and make sure all data permissions are "enabled". Then, close and reopen PeakWatch;
  2. Check if there is sleep data in the Apple Health app. If there is no data in Apple Health, PeakWatch cannot retrieve it;
  3. If you are using a third-party app, make sure it's one like Pillow that writes sleep stages to Apple Health;
  4. Check PeakWatch's sleep data priority:
    1. In "Settings" -> "Sleep" -> "Sleep Data Source", check the priority order.
    2. If the top priority is set to iPhone (bedtime), and the data source doesn't provide detailed sleep stages, PeakWatch will only show sleep duration without detailed sleep quality assessment.
    3. If the top priority is a third-party app like AutoSleep that doesn't support sleep stages, PeakWatch cannot provide a sleep quality evaluation. Do not set AutoSleep as the top data source priority.
  5. If after these steps you still don't have data, go to "Settings" -> "Contact Us" to get assistance.

How to enable sleep tracking on the Apple Watch?

To use the Apple Watch for sleep tracking, the following conditions must be met:

  • iOS 16 and above, watchOS 9 and above;
  • In the Watch app on the iPhone, enable "Track Sleep with Apple Watch";
  • The watch must be in sleep mode during sleep;
  • The watch must be unlocked and have sufficient battery;
  • Sleep mode should be enabled for at least 4 hours. For more details, refer to Apple's official documentation: https://support.apple.com/guide/watch/apd830528336/10.0/watchos/10.0

Why is my sleep data different from that displayed in the Apple Health app?

The sleep data in the Apple Health app is influenced by its data source priority settings. To align it with PeakWatch:

  1. Open the Apple Health app -> Browse -> Sleep -> Data Sources & Access;
  2. Scroll down to Data Sources and tap the "Edit" button in the top right corner;
  3. Enable and adjust the sleep data priority to match PeakWatch's priority settings. This will ensure that the data displayed in both apps is consistent. However, minor differences (e.g., a few minutes) may still occur due to data access and rounding, which is normal.

Why are manually added sleep data not syncing?

PeakWatch reads sleep data from Apple Watch, iPhone, and third-party apps but only selects one data source. By default, PeakWatch prioritizes sleep data in this order:

  • Apple Watch;
  • Third-party app;
  • iPhone (bedtime). Manually added sleep data belongs to the iPhone source and is not the same as data from the Apple Watch, so it is not recorded. For complete sleep data, it's recommended to consistently use the same data source, such as wearing the Apple Watch all day and using Apple Watch as the data source.

Why is time in bed not recorded in my sleep data?

As mentioned above, time in bed is an iPhone data source. PeakWatch only supports one sleep data source at a time. When PeakWatch's primary sleep data source is non-iPhone, time in bed will not be recorded. To get complete sleep data, it's recommended to consistently use the same data source, such as wearing the Apple Watch all day and using it as the data source.

Why is there no nap data in PeakWatch?

Currently, iOS does not support nap tracking.
Once iOS version 18.0 supports nap tracking, PeakWatch will adapt accordingly.

When should I adjust the sleep data source?

If you feel that the data from your Apple Watch does not accurately reflect your actual sleep patterns, and you want to use data from a third-party app, you can manually adjust the sleep data priority in PeakWatch by going to "Settings" -> "Sleep" -> "Sleep Data Source".

Please note that we recommend setting data sources that support both "sleep duration" and "sleep stages" as the highest priority. If your preferred data source only supports sleep duration (e.g., AutoSleep), you will not see PeakWatch’s sleep quality evaluation based on sleep stages.

Why are there two entries for the same sleep session?

Check if you are using a third-party app to record your sleep as well.
If you do not want duplicate data, you can delete one of the entries in the Apple Health app.

Why is there no sleep data on the home screen, but only sleep duration?

Check if your sleep data source is a third-party app like AutoSleep, which does not support writing sleep stages to Apple Health.
If PeakWatch cannot access detailed data such as sleep stages, it will only display the sleep duration data.

Body Battery

Why doesn't napping increase body battery?

Currently, Apple only supports automatic nap tracking in iOS 11 and watchOS 18 beta.
PeakWatch will not support this feature until Apple officially releases the final version of these operating systems. After the official release of iOS 11 and watchOS 18, PeakWatch will be adapted to support this functionality.

Why is my body battery status opposite to my recovery?

"Body Battery" is mainly calculated based on the body's stress levels, including heart rate, exercise expenditure, and sleep, reflecting physical energy consumption.
"Training Readiness," on the other hand, is calculated by analyzing HRV (Heart Rate Variability) and RHR (Resting Heart Rate), reflecting the body's capacity to handle exercise intensity.

Think of the body like a smartphone: body battery is similar to battery charge, and training readiness is like CPU processing power. These two measurements are not contradictory, and there may be situations where body battery and training readiness appear to be at opposite levels.

For example:
If someone stayed up late and their body battery is only at 30%, but their training readiness is at 90%, it means that while the body may not have fully recovered physically, their HRV and RHR metrics are still in a good range, indicating they can handle a training session. However, energy reserves are low, so caution is needed.

So, should you train under these circumstances?
We do not recommend it. Without proper rest and recovery, the effectiveness of training may be reduced, and you risk injury, making it unwise to proceed with exercise.

What should I pay attention to when using PeakWatch's "Body Battery"?

  1. The initial loading of body battery data may take a few minutes;
  2. Body battery is integrated into the app's overall caching system. If you want to clear the cache and recalculate your body battery, you can go to "Settings" and select "Clear Cache and Recalculate."

Recovery

How can I get more accurate recovery?

Recovery is based on HRV data, so the more HRV samples available, the more accurate your readiness score will be.
Here’s how to get more accurate HRV data:

  • Wear your Apple Watch to sleep, allowing it to collect HRV data overnight;
  • Upon waking, use the Apple Watch's built-in "Breathe" app to trigger an HRV measurement. Breathe normally rather than following the deep-breathing prompts, as deep breathing can artificially raise your HRV;
  • Enable the Atrial Fibrillation (AFib) function to increase the frequency of HRV measurements.

Why does my recovery change?

  • Check if your Apple Watch recorded HRV and RHR data during the night:
    1. If you wore your Apple Watch while sleeping and it recorded HRV and RHR, PeakWatch will calculate your readiness after syncing the data in the morning. Training readiness is updated only once in the morning.
    2. If you did not wear your Apple Watch to sleep or if HRV and RHR data were not captured overnight, PeakWatch will use HRV and RHR data collected throughout the day to estimate readiness. In this case, readiness may change throughout the day as HRV and RHR fluctuate.
    3. We recommend wearing your Apple Watch while sleeping to capture these important nighttime HRV and RHR values, which are critical for assessing recovery and ensuring more accurate readiness scores.
  • Check if the resting heart rate (RHR) in the Apple Health app fluctuates:
    The Apple Health app shows only one resting heart rate value per day, but RHR can sometimes change during the day. PeakWatch pulls this data, and if there is a change, it will update your training readiness score accordingly.

Why does recovery not match how I feel?

While your subjective feelings are important, they are influenced by various factors that may not be directly related to training readiness, such as emotions from dreams, hunger, or even the weather.
Training readiness, on the other hand, is calculated based on objective health metrics like HRV and RHR, providing a more reliable indicator of your body's preparedness for exercise.

We recommend considering both subjective feelings and training readiness when planning your workouts, with training readiness serving as a valuable reference.

If my recovery doesn’t match how I feel, should I still follow the training suggestions?

PeakWatch serves as a training tool, and its daily workout suggestions are for reference only.
It’s best to listen to your body’s signals while also considering the training recommendations. Take into account factors such as recent diet, emotional state, stress, and other influences that your watch cannot monitor when deciding whether to train.

Exertion

Why is it difficult to reach 100% exertion?

Due to the "law of diminishing returns" (whereby as training intensity increases, the body gradually adapts to the workload, resulting in smaller gains), PeakWatch's Exertion is not a linear progression. It’s challenging to hit 100% exertion, unlike closing the rings on the Apple Activity app, unless you’re engaging in an extraordinary amount of physical activity, such as running a full marathon in one day.
For the average fitness enthusiast, it’s not recommended to aim for 100% exertion.

PeakWatch recommends a personalized workout range based on your current training readiness and chosen training mode:

  • When training readiness is high, the recommended range is adjusted upwards; when readiness is low, the range is adjusted downwards.
  • In "Settings" -> "Training Mode", different modes correspond to different intensities. Choosing a higher intensity mode will increase the recommended range, while a lower intensity mode will decrease it.

This depends on the accuracy of your maximum heart rate (MHR).
If your heart rate readings are unusually high, it will be more difficult to reach the recommended exertion range (e.g., if your heart rate monitor shows 210 when your actual maximum should be 186).
Conversely, if your heart rate readings are lower than expected, it may be easier to reach the target range, especially if you are just getting back into training.
If you know your exact MHR, you can manually adjust it in the settings to help improve the accuracy of the recommended range.

Energy Intake

Why is there no data for my energy intake?

PeakWatch pulls data from the Apple Health app. To record your energy intake, you can use a third-party app that supports writing to Apple Health (such as "Keep").

Once you’ve recorded your intake, check that the data (such as "Dietary Energy", "Protein", "Carbohydrates", and "Total Fat") has been successfully synced to Apple Health. PeakWatch will display this information once it’s available.

Why is some of the energy intake data missing?

Check whether the Apple Health app has recorded values for "Dietary Energy" (listed as Energy Intake in PeakWatch), "Protein", "Carbohydrates", and "Total Fat".
If any of these values are missing, PeakWatch will not display the corresponding data.

Workout Details

Why does the intensity of strength training not match how I feel?

Workout intensity is primarily assessed based on the proportion of time spent in different heart rate zones, which reflects cardiovascular load. However, strength training places more load on the muscular system, which is difficult for the Apple Watch to monitor.
As a result, the workout intensity reported by PeakWatch may not match how you feel, as your muscles might experience significant strain while your heart rate remains relatively low.

If strength training makes up a large part of your workouts, we recommend using "Training Readiness" to help guide your training plans.

Why is the impact of training on HRV not displayed?

If you haven’t enabled the AFib function, the Apple Watch collects HRV data less frequently (about every two hours, or even less often).
If the Apple Watch doesn't record HRV data immediately after your workout, PeakWatch will not be able to analyze the impact of your training on HRV.

You can use the "Breathe" app on the Apple Watch after training to trigger an HRV measurement, but remember to breathe normally instead of following the deep-breathing prompts, as deep breathing can inflate your HRV. This will help PeakWatch capture more accurate HRV data after your workout.
