We’ve teamed up with a range of partners, giving the Clue community more opportunities to sync various wearable devices.

Launching in late October 2025, you can connect wearables from Oura, Withings, Ultrahuman, HUAWEI and Whoop. Watch this space for more to come.

The Clue wearable integrations allow people to seamlessly sync selected biometric data from their wearable into the Clue app. Right now, the biometrics that can be synced are skin temperature trends and sleep duration data.

Once someone has successfully connected a wearable with their Clue account, the integration works by the person’s device measuring their biometrics and then automatically sharing that data with Clue via the partner’s API provider. This data is then used to create data visualizations in the Analysis Tab of the Clue app, showing the biometric readings alongside the person’s cycle phases.

Seeing your biometric data in Clue can give you a deeper understanding and more complete view of your cycle.

You’ll be able to identify how your sleep and temperature change in different phases of your cycle. This can help you make correlations between things like:
‍

Temperature trends and ovulation

‍Many wearables measure skin temperature while you sleep. This isn’t the same as basal body temperature (BBT), which is measured with a thermometer right after waking up. Here are some helpful things to know:

• BBT reflects subtle hormonal changes. For example, it’s slightly lower in the first half of the cycle (follicular phase), then rises after ovulation and stays higher throughout the second half of your cycle (luteal phase).
• Some wearables can show similar up-and-down patterns in skin temperature. These patterns can give you clues about where you are in your cycle. 
• Not all wearables measure temperature the same way. For details about how your device works, check the information from the manufacturer.
• These patterns are only visible if you’re having natural ovulatory cycles. If you’re using hormonal birth control, ovulation is typically suppressed, so you won’t see the same temperature shifts.

Sleep and energy levels

‍Hormones that shift across your cycle can affect how well you sleep and how much energy you feel you have. By linking sleep data from your wearable with cycle tracking in Clue, you may notice patterns in how rested or energized you feel in different phases of your cycle.

This awareness can help you tailor your daily activities, like planning workouts for days when your energy is higher, allowing more recovery when your sleep has been disrupted, or adjusting your schedule to better support your well-being.
‍

‍Sleep and moods

‍Sleep is closely tied to mental well-being. Poor sleep can make mood changes feel stronger, while good sleep can help balance them out. Seeing your sleep patterns alongside mood tracking in Clue can help you explore how these factors interact in your own cycle.

This can give you a clearer picture of whether your mood shifts are more connected to cycle phases, sleep duration, or both. With that awareness, you might choose to prioritize rest on days when you anticipate more emotional sensitivity, build in calming routines, or be kinder to yourself when you notice patterns emerging.

‍Disclaimer: Temperature and sleep data from wearables are intended for general wellness insights only. They are not diagnostic tools and should not be used to confirm or rule out medical conditions. Importantly, temperature data from wearable devices cannot be used as a method of contraception. For questions about contraception or medical concerns, please consult a healthcare provider.

Yes, you’ll need an active Clue Plus subscription to connect your wearable device. This integration feature is part of our premium offering that gives people the tools to understand their cycle health in a deeper way.

At this stage, only temperature trends and sleep duration data can be synced. We’re currently looking into other biometric data that can be shared to bring even more value to these wearable integrations.

When you first connect your device in the Clue app settings, you’ll be asked which wearable data you’d like to share with Clue. If you disconnect your device from Clue, then the data sharing will stop.

When wearable data is shared with us, it’s treated with the same care as all your other health data that you track in the Clue app—with privacy, security, and protection under the GDPR. You can read more about how we handle data in our Privacy Policy.

Clue does not share any of your Clue data with your wearable device, or the corresponding company and their apps.

The integrations are set up to be one-way, meaning only your biometric data is shared with Clue.
