BluCon NightRider is a small Bluetooth transmitter made by Ambrosia Systems that sits on top of a compatible continuous glucose sensor and relays readings to your phone or smartwatch. It is designed to turn an intermittently-scanned sensor into a near real-time monitoring system, with the CE mark confirming European regulatory approval.

Key features

• CE marked — has cleared European conformity requirements for medical use.
• Smartphone pairing — connects to both Apple and Android devices over Bluetooth without manual scanning.
• Smartwatch ready — readings can be pushed to Apple Watch and Android Wear faces through supported third-party apps.
• Sensor compatible — works with the FreeStyle Libre 2 sensor for users who want continuous data rather than tap-to-read scans.
• Background monitoring — keeps streaming values overnight, which is the use case the NightRider name points to.
• Compact transmitter — clips over the existing sensor patch so you do not need a second site on your skin.
• Sold by Ambrosia Systems — the original manufacturer handles distribution and support directly.

This is aimed at people managing diabetes who already use a flash glucose sensor but want hands-free, always-on numbers, alerts, and trend arrows.

Use happens anywhere a phone or watch travels - home, work, or the gym.

How does and Apple/Android watches. BluCon NightRider received the CE mark. FreeStyle Libre 2 compare?

Compared with using a sensor on its own, this transmitter removes the need to physically scan and adds continuous streaming plus alarms. Against fully integrated continuous glucose monitoring systems, it is typically a lower-cost route because you keep using sensors you already buy, though it relies on third-party apps rather than one vendor-locked ecosystem. Versus generic Bluetooth bridges, the CE mark gives it a regulatory credential that many open-source alternatives lack.
