GlucoLine streams your FreeStyle Libre 2 and Libre 3 readings to your phone, watch, and home screen — with widgets, complications, Live Activities, and custom range alerts.
Read your sensor wherever you naturally look — wrist, lock screen, home screen, even your app icon.
Standalone watch app shows your current value, trend arrow, and a 24-hour mini chart — even when your phone is across the house.
Your reading lives on the lock screen and in the Dynamic Island, updating in real time without unlocking your phone.
Small, medium, and large widgets with your latest value, trend arrow, and chart — choose what fits your home screen.
Add GlucoLine to any watch face — circular, corner, modular, or inline complications, with smart-stack rotation support.
Per-band thresholds for low, in-range, and high glucose — choose tones, repeat intervals, and quiet hours.
No ads, no trackers, no data brokers. Your readings live on your devices and on a backend dedicated to making your widgets work.
No new sensor, no new account — bring your existing Libre setup.
