Product Questions
What does the Rsuntek device track?
Rsuntek devices continuously track key biometric signals including heart rate, heart rate variability (HRV), resting heart rate, sleep stages, recovery score, daily strain, and skin temperature. The data is translated into clear daily insights on the Rsuntek app.
Is the device waterproof?
Yes. Rsuntek devices are water-resistant up to 1 meter for short periods (e.g. showering, hand washing). We do not recommend wearing the device while swimming in chlorinated or salt water for extended periods, as this can degrade the band over time.
How long does the battery last?
On a single charge, the battery lasts approximately 5–7 days with normal use. Heavy continuous monitoring (e.g. workout tracking with GPS connected) reduces battery life. Charging from 0 to 100% takes about 90 minutes.
Do I need a subscription to use Rsuntek?
The Rsuntek device works out of the box for basic tracking. The Rsuntek Membership unlocks advanced insights, long-term trend analysis, personalized recommendations, and the full ecosystem of coaching content. You can activate or cancel the membership at any time.
Is my health data private?
Absolutely. Your personal health data is encrypted end-to-end, stored securely, and never sold to third parties. You can export or permanently delete your data at any time from your account settings. Read our full Privacy Policy for details.
Which devices and operating systems are supported?
The Rsuntek app is available for iOS 14 and later, and Android 9 and later. The device syncs via Bluetooth Low Energy (BLE).
How accurate is the data?
Rsuntek sensors are validated against clinical-grade reference devices. Accuracy may vary based on fit, motion, and individual physiology. The device is not a medical device and is intended for general fitness and wellness purposes only.
