Glynce

Glynce is an iPhone app for adults with diabetes that combines glucose readings, meals, carbohydrate intake, activity, and other health data in a customizable dashboard. It connects to Dexcom G6 and G7, FreeStyle Libre 2 and 3, Medtronic Guardian, Medtrum, Eversense, and Nightscout. Abbott Lingo, Stelo, and other sensors can connect through Apple Health, while glucose readings can also be entered manually. CGM data is sent directly from the CGM service to the phone without passing readings or CGM credentials through Glynce servers.

Meals can be logged with photos, nutrition-label or barcode scans, and food search, with estimates for carbohydrates, protein, fat, and calories. The app displays meals alongside glucose curves and provides Time in Range, average glucose, estimated HbA1c, standard deviation, coefficient of variation, and time-of-day heatmaps. Apple Health integration supports heart rate, HRV, steps, workouts, and VO2 Max. It also includes Apple Watch support, widgets, Live Activities, Dynamic Island, StandBy, CarPlay, reminders, goals, and PDF reports for selected date ranges.

The free version includes core tracking features. Glynce Plus adds meal analysis, advanced statistics, additional widgets and CarPlay features, custom goals, and additional insights. Glynce is a self-tracking and lifestyle app, not a medical device, and does not replace CGM or insulin-pump software, healthcare providers, or medical advice.
