BioSense™ Technology is Oxiline’s integrated biometric sensing platform, combining advanced optical and motion sensors with proprietary signal-processing algorithms to capture, refine, and interpret physiological signals from the wrist.
Band XS Pro provides up to 40 days of battery life in Low-Power Mode, where heart rate is recorded every 5 minutes, or up to 12 days in Continuous Monitoring Mode.
Yes. Band XS Pro can continue recording data without your phone nearby and stores up to 7 days of monitoring data directly on the device. When you reconnect to the Oxiline Health App, stored data automatically syncs to your account.
Most everyday monitoring happens automatically. You can also initiate supported spot measurements when you want an immediate reading or a more focused measurement session.
Choose your activity in the app or supported workout mode and Band XS Pro will collect relevant biometric and movement data throughout the session.
Band XS Pro is designed to help you monitor health, wellness, and fitness trends. Measurements and calculated insights should not be used on their own to diagnose or treat a medical condition. For medical decisions, consult a qualified healthcare professional.
Band XS Pro is ideal for anyone who wants a clearer, more continuous view of their health without the size or distractions of a traditional smartwatch. It’s especially well suited for users focused on heart health, sleep, recovery, activity, and long-term wellness trends, as well as those who prefer a lightweight device they can comfortably wear day and night. It is also a good fit for older adults who want simple, continuous health tracking without learning a smartwatch.
Yes. Band XS Pro is a full sleep tracker. It records total sleep, sleep stages (light, deep, REM and awake), sleep efficiency, time to fall asleep and wake events, along with overnight heart rate, HRV, SpO₂ and skin temperature, and gives you a sleep score each morning. With no screen and up to 40 days of battery, there is nothing to charge overnight.
Yes. Band XS Pro pairs over Bluetooth 5.0 Low Energy with the Oxiline Health App on iPhone (iOS) and Android. Data syncs automatically whenever your phone is nearby, and the band keeps recording on its own when it is not.
Yes. Band XS Pro is IP68 rated and water resistant to 10 meters, so you can wear it in the shower, in the pool and through sweaty workouts. Use the ActiveFlex™ Strap for water and training, and the ComfortWeave™ Strap for daily wear and sleep.
Yes. In the Oxiline Health App, pick any date range and export it as a PDF report with daily charts for each metric. Send it to your doctor, coach or family in a tap, or keep it for your own records.
