FreeStyle LibreLink SG for iPhone

App summary

FreeStyle LibreLink SG, created by Abbott Diabetes Care Inc., is a mobile application designed to help people with diabetes check their glucose levels using the FreeStyle Libre sensor. The app allows users to obtain glucose readings by scanning the sensor with a compatible iPhone and review patterns over time.

Primary capabilities

• Historical glucose data, including past readings and trend visualizations.
• Instantaneous glucose value plus an indicator showing whether levels are rising or falling.
• Built-in summaries such as Daily Patterns and Time-in-Range that highlight routine glucose behavior.
• Options to transmit glucose information to clinicians or family members when the user chooses to share.

Device compatibility and requirements

• Compatibility differs across phone models and operating system versions; verify your device before relying on the app exclusively.
• A complete list of supported phones and OS requirements is available on the FreeStyle Libre website.
• The app is intended for use only with the FreeStyle Libre sensor and is intended to assist in glucose monitoring for people living with diabetes.

Using the reader and the app together

• If you plan to use both the dedicated reader and the smartphone app with the same sensor, begin by initializing the sensor with the reader.
• After the reader starts the sensor, you can then scan the sensor with your phone to view readings in the app.
• Using both devices for one sensor is supported, but follow the manufacturer’s instructions to ensure the sensor is activated correctly.

Getting started (quick steps)

1. Confirm your phone model and operating system are supported.
2. Start the sensor using the reader if you’ll be using both the reader and the app.
3. Open FreeStyle LibreLink SG on your iPhone and scan the sensor to receive readings.
4. Review reports and, if desired, enable data sharing with your clinician or family.

Support and documentation

• The app contains a User’s Manual with detailed guidance on features and safe operation; review it for step-by-step instructions.
• For questions that the manual doesn’t answer, contact Abbott Diabetes Care Customer Support for assistance.

Alternative options

• For those evaluating continuous glucose monitoring systems, consider other commercially available CGM products such as the Dexcom G7 as a potential alternative depending on personal needs and provider recommendations.

Final note

FreeStyle LibreLink SG provides an accessible way to monitor glucose trends on a smartphone. When used correctly and on a supported device, it can help users track glucose history, view trend indicators, and share information with care partners to support diabetes self-management.
