FreeStyle Libre 3 - IT for iPhone

Quick summary

The FreeStyle Libre 3 system pairs a small, wearable glucose sensor with a smartphone app to provide continuous glucose monitoring (CGM) for people with diabetes. Glucose values are sent to your phone every minute so you can view near–real-time glucose information and trends.

Main capabilities

• Delivers glucose updates to your smartphone on a one-minute cadence for near real‑time awareness.
• Offers optional alerts that notify you when glucose levels are above or below your chosen thresholds.
• Produces detailed analytics and reports — including time‑in‑range metrics — to help you track patterns and make informed decisions.
• Designed specifically to work with the FreeStyle Libre 3 sensor; it is not backward compatible with earlier FreeStyle Libre or FreeStyle Libre 2 sensors.

Sensor highlights

• The FreeStyle Libre 3 sensor is extremely compact and thin, engineered for discretion and comfortable wear.
• Provides up to 14 days of continuous glucose monitoring per sensor insertion.
• Built to maintain reliable and accurate readings while offering strong connectivity to the paired smartphone.

Compatibility and requirements

• App compatibility depends on your smartphone model and operating system version; check device requirements before downloading.
• The app only functions with FreeStyle Libre 3 sensors — it will not communicate with FreeStyle Libre or FreeStyle Libre 2 devices.

Alternatives and next steps

• If you’re exploring other CGM options, the Dexcom G7 is frequently suggested as an alternative system.
• To get started, download the FreeStyle Libre 3 app that matches your device’s app store and review compatibility details.
• Speak with your healthcare provider to determine whether this CGM system is appropriate for your needs and to receive guidance on setup and interpretation of glucose data.
