1. AI-Powered Features

All our AI capabilities work with any iOS or Android device—you don’t need a Samsung- or Apple-only phone. Simply download our app and you’re good to go.

2. Heart-Rate Monitoring

This feature is designed for general wellness insights only. It is not a medical device and should not be used to diagnose, treat, mitigate or prevent any health condition.

3. Smartphone Requirement

A compatible smartphone is required to pair with the device and access all features in our app.

4. Energy Score Insights

Your Energy Score is generated entirely from your tracked data—no special AI-enabled phone or brand-specific account is necessary. Just wear your device and open the app.

5. Data Tracking

All metrics are captured through our own application. You don’t need any particular phone model or branded account to see your data.

6. Calibration Period

To ensure accurate AI-powered reports, wear the device every night for the first 7 nights within any 30-night window. This initial week of continuous wear provides the baseline our algorithms need.

7. Snore Detection

For snore tracking to work, keep your phone within 2 feet of your bedside and enable snore detection in the app settings.

8. Cycle Tracking

Use Cycle Tracking to log menstrual cycles—but it is not a contraceptive tool. If you’re on hormonal birth control or other treatments that prevent ovulation, this feature won’t predict ovulation. Accuracy can also be affected by wearing time (we recommend at least 4 hours nightly, five nights a week), manual inputs, and external factors like illness, travel or routine changes. Always consult a healthcare professional before making any medical decisions, and note that Cycle Tracking is intended for users aged 18 and up.
