About this app

DiaBest is a diabetic watch face for people with type 1 diabetes (T1D) who use continuous glucose monitoring (CGM). View your glucose (blood sugar) data on compatible Wear OS smartwatches.

See glucose, the trend arrow, reading age and a graph on the main screen. When available through Dia.best, the panel also shows active insulin, carbohydrates, time in range and calculated forecasts. The carbohydrate entry button opens the matching screen in the Dia.best watch app.

Glucose information requires Dia.best on both your phone and watch, a configured glucose data source and a connection between the devices. If you use Nightscout, connect it in Dia.best before using the watch face. The watch face does not connect directly to CGM sensors and does not measure glucose. Data and available readings depend on your connected source.

English and Russian are supported. The data panel follows the language selected in Dia.best on your phone. A large white clock improves readability, with a dimmed display in ambient mode.

Requires a compatible watch running Wear OS 6 or later with Watch Face Format 4 support. This watch face is not a phone app.

Do not use the watch face as your only basis for treatment decisions. Check the age of the latest reading and follow your sensor manufacturer's instructions and your healthcare professional's guidance.
