Are the memberships and data between Android and iOS intercompatible?

Currently, they are not intercompatible because:

The data acquisition methods and functions available on Android and iOS are different
We do not store users’ health data in the cloud; the current data is directly read from various sports health apps, so health data migration is not supported.
It may be supported in the future

Some data on iOS phones do not display

Reason 1: The wearable device may not support the data

If you are an Apple Watch user: Different models of Apple Watch can collect different data. For example, the Apple Watch SE cannot record blood oxygen and wrist temperature, which may cause some data in the app to be empty.
If you are a user of other wearable devices: OtterLife can only read data stored in Apple Health. If the sports health app associated with your device does not support measuring or writing certain data, some data in the app (such as HRV) may be empty.

Reason 2: Wearable device data not updated

OtterLife relies on health data uploaded from sports wearable devices like Apple Watch. If you do not wear the watch or band during exercise or sleep, we will not be able to obtain your health data.

HRV data: When you are wearing the Apple Watch normally, HRV data will be automatically updated every 2-5 hours. There may be delays in data updating and pushing due to Apple’s system reasons.
You can also open the “Mindfulness” app on the watch, select the “Breathing” function, and complete one session to update to the latest data.
Other data: Due to the limitations of the Apple Watch itself, there will be a certain interval for each data synchronization. If the data does not update immediately, you can try again later.
If you are using other wearable devices, it may be due to lack of timely data synchronization. You can open the corresponding sports health app for synchronization.

Reason 3: Apple Health data permissions not authorized

If you are using other health apps to track body data but OtterLife does not have data, it is most likely because data is not shared with Apple Health.
OtterLife relies on Apple Health authorization to ensure the accuracy and timely update of data and to provide you with statistics and notifications. Not turning on all the authorizations will affect your experience of the full functionality of the product.

Refer to the tutorial below to open all permissions by going to iOS Settings – Privacy & Security – Health – OtterLife and clicking “Open All,” ensuring OtterLife can function properly.

Android + Huawei device data synchronization issues

OtterLife pulls data from Huawei Cloud, and the lack of cloud synchronization on your Huawei device may cause this issue, which is different from the data acquisition method of Huawei Sports Health. You’ll have to wait patiently to see if the data can recover on its own.
Confirm whether the Huawei Sports Health and OtterLife accounts logged in are the same.

Apple Watch related

What to do if you can’t find “OtterLife” when adding a complication, or if the complication suddenly turns black on the watch?

If the “Watch” app on the phone shows empty, it may be a bug from Apple, and the watch may not actually be empty.
Please check the app list on the watch to see if “OtterLife” has been installed. You can go to “Watch” – “My Watch” and scroll to the bottom to check the installation status.
If you have already installed it on the watch successfully, you can long press the watch face – “Edit” – swipe left to switch to “Complications,” find “OtterLife,” and add it.
If you can’t find “OtterLife” in “Complications” on the watch, open the phone’s “Watch,” find “OtterLife” – “Don’t Show” – scroll to the bottom of “Watch” to find and reinstall “OtterLife.”

What to do if you get a prompt “Complications unavailable” when adding them on the phone?

This issue is primarily a bug with Apple Watch, mainly occurring during app updates.
Check if “OtterLife” has been successfully installed on the Apple Watch. If it has, you can long press the watch face – “Edit” – swipe left to switch to “Complications,” find “OtterLife,” and add it.
If you can’t find “OtterLife” in “Complications” on the watch, open the phone’s “Watch,” find “OtterLife” – “Don’t Show” – scroll to the bottom of “Watch” to find and reinstall “OtterLife.”

What to do if the app installation on the watch fails or remains stuck?

First, go to “Watch” – “My Watch” and scroll to the bottom to check the installation status of “OtterLife.”
On the watch, enter the App Store, scroll to the bottom to find the account – Purchased Items, find “OtterLife,” and click download.
Please check if the phone and watch are connected to the same Wi-Fi. You can disconnect and reconnect the watch Wi-Fi, and turn the airplane mode on and off.
Is the Bluetooth connection normal? → Disconnect and reconnect the watch’s Bluetooth.
If you are using mobile data on the phone, check if there are any pop-ups on the watch confirming the download.
Are multiple apps being downloaded at the same time? → Terminate all, and then download them one by one.
If none of the above issues exist, you can try long pressing the crown to restart the watch. If the issue persists, please contact customer service for assistance.

What to do if the watch complications show “No Data” or fail to update normally?

Check if the corresponding permissions have been authorized? Go to “Settings” on the watch – “Health” – “Apps and Services” – “Otter Health,” and select “Open All.”
Is there any data update?

When you wear the Apple Watch normally, it automatically updates your HRV data every 2-5 hours. There may be delays in data updating and pushing due to Apple’s system issues, thank you for your understanding. You can also open the “Mindfulness” app on the watch, select the “Breathing” function, and complete one session to update to the latest data.

If the above does not solve the issue, please contact customer service jikeqa for feedback.

HRV

What is HRV?

HRV, also known as heart rate variability ❤️, records the small differences in your heart rate between each beat. HRV can reflect your body’s ability to cope with stress ⚡, fatigue 😴, or illness 🤒.

Is HRV scientific?

The human body primarily reflects stress through the autonomic nervous system. Under stress, the sympathetic nervous system becomes more active, speeding up the heartbeat, reducing the interval between beats, and therefore decreasing HRV 📉; in relaxation or recovery states, the parasympathetic nervous system becomes more active, slowing down the heartbeat, lengthening the intervals, and thus increasing HRV 📈.

What HRV values are better?

Each person’s HRV reading is unique and influenced by many factors such as age 👩🏼👩🏼🦳, gender 👩🏼👱🏻♂️, etc. Therefore, stable HRV data over time is more accurate in reflecting individual health status 😇 than a single high or low HRV reading. So there’s no need to feel anxious about occasional low HRV 😌!

Understanding HRV more intuitively!

Stable HRV data 📊 can more accurately reflect individual health status. Therefore, we calculate your average HRV over the past 30 days and tell you the state of your body: When HRV is much higher than average: Good things are happening When HRV is within the normal range: Full of vitality When HRV is much lower than average: High stress

Why is the HRV data measured different from that in Apple Health?

Because Apple Health uses the SDNN algorithm, while we use the rMSSD algorithm. In simple terms, SDNN assesses long-term heart rate variability, while rMSSD focuses more on short-term heart rate variability, making it more suitable for observing daily HRV changes.

How often is data updated?

When you wear the Apple Watch normally, HRV data is automatically updated every 2-5 hours. There may be delays in data updating and pushing due to Apple’s system reasons, thank you for your understanding. You can also open the “Mindfulness” app on the watch, select the “Breathing” function, and complete one session to update to the latest data.

Why can’t it update in real time?

HRV data updates primarily rely on updates from Apple Health for heart rate variability, which updates randomly every 2-5 hours on the Apple Watch. (If the fibrillation function is enabled, the refresh rate will be higher). Heart rate variability (Figure 1) depends on beat-to-beat measurements (Figure 2) taken within one minute by the heart; any calculations derived from other methods are meaningless and valueless. Therefore, updating is currently not supported on the Apple Watch.

Sleep

Why is there no recorded sleep data on Apple Watch?

Open sleep tracking.

First, ensure that sleep monitoring is enabled on the Apple Watch and wear the watch while sleeping for more than 7 days so that the Apple Watch can learn your sleep habits to generate more accurate sleep data. If you want more accurate sleep tracking, set sleep timings and sleep goals. Additionally, if each sleep duration is less than 4 hours, sleep data cannot be generated.

Set sleep timings.

On the phone, open the “Watch” App, select “Sleep” – “Manage sleep focus mode in settings” – set “Sleep Timings.” If sleep mode is not turned off after waking up, sleep will be recorded until the sleep mode’s end time.

Why can’t the phone record sleep?

After the iOS 18 update, it is no longer possible to record sleep duration through the phone.

Does it support reading sleep recorded by other apps?

Go to the sleep detail page, choose settings in the upper right corner, and switch the data source. Selecting “Smart Selection” will limit the data source list to those with sleep stage data (Apple Watch takes priority).

Is sleep duration incorrect?

Please check if you have modified the sleep statistical cutoff time; the app will use this time to separate sleep statistics. It is recommended to set the latest end time for naps and short sleeps to any time within the earliest start time for nighttime sleep.

How to track naps

After updating to watchOS 11, if you have enabled the sleep feature and wear the Apple Watch, it will automatically track naps without additional actions. Naps of less than 30 minutes are unlikely to be detected by the watch. For naps longer than 30 minutes, the watch may record your nap, but the recorded data will not include sleep stages (such as deep or light sleep). The longer you sleep, the higher the likelihood of being recorded, with sleep stage information only documented for sleeps longer than 2 hours.

Menstruation

How to view wrist temperature data

Supported only on Apple Watch Series 8, 9, 10, Ultra, Ultra 2 models.
Open “Track Sleep Through Apple Watch” to set “Sleep.”
To establish a temperature baseline, ensure sleep focus mode is enabled and wear the Apple Watch during sleep.
You must track sleep for at least four hours each night to collect wrist temperature data from the Apple Watch. Wrist temperature data will typically be available after about five nights.

[Note] Your body temperature naturally fluctuates and can vary each night due to various factors. Wrist temperature may also be affected by external factors such as the sleep environment.

Exercise and activity tracking related

If there are no recent exercise records, the fitness module in the navigation bar is hidden.
iOS only supports exercise recorded from Apple Watch, does not support exercise records from other devices.
Huawei only supports exercise recorded from Huawei watches/bands, does not support exercise records from phone classes.
Xiaomi and phone sources do not support exercise records.

Will weight trends, sun exposure time, and other data be added later?

There are development plans.

—————— Subscription and membership related issues ——————

Is there a discount plan?

We offer a permanent membership discount for our long-time supporters, but the early bird discount has currently ended. Future promotions may occur during Double Eleven and other holidays, please follow the official Xiaohongshu account or official Jike account for updates.

If I am a current member, can I still use it after switching phones?

iOS side: Membership purchases follow your Apple ID, so after changing phones, use the same ID to click the “Restore Purchase” option at the top right of the purchase page to restore membership status. Android side: Membership purchases follow your WeChat account, so after changing phones, log in using the same WeChat account. Note: Memberships across both platforms are not intercompatible.

What should I do if I have a current subscription and want to upgrade to a permanent membership?

Currently, we do not support upgrade operations, and this functionality will be developed in the future. To become a permanent member, your current status must be non-member.

If I click on the trial, will I be charged if I cancel the subscription during the trial period?

Under normal circumstances, you will not be charged if you cancel the subscription during the trial period. However, if you do not cancel the subscription after the trial period ends, you will be charged directly.

Why was I charged directly after clicking on the trial?

If you have previously tried this product, clicking on the trial again will result in immediate charges (the confirmation message before charging will be different). Figure 1: Clicking to trial a product for the first time. Figure 2: Having previously tried this product, clicking trial again will lead to immediate charges.

Can members issue invoices?

Developers cannot provide the function to issue invoices. Here is the official response: “Apple does not provide invoices for app subscription purchases in China.”

Membership refund issues

iOS

Official refund process

You can initiate a refund request through Apple’s official refund link: https://support.apple.com/zh-cn/HT204084

My refund request was denied?

First, you should note that all refund requests for App Store apps are handled uniformly by Apple; developers cannot control the refund process. Developers only receive notification when Apple successfully processes a refund. Generally, refund requests are usually approved, but approval primarily depends on Apple. Since your payment is held by Apple and periodically transferred to developers, not directly to developers, if Apple customer service advises you to contact developers for negotiation, in fact, developers have no way to process refunds. Furthermore, accounts that frequently request refunds may be flagged by Apple’s risk management system. In this case, we may not be able to provide a refund, due to Apple’s policy. We understand your concerns. If you have further questions, please add our customer service: jikeqa
