RangeTrace

Keep the latest Dexcom Share reading beside your Mac’s clock. Add the trend arrow, change since the previous reading, or a tiny graph to get the context you need without opening another app.

Open RangeTrace to see your time in range, low and high percentages, average glucose, and estimated GMI. Your day is only one click away.

Turn on alerts for urgent low, low, high, urgent high, signal loss, fast changes, or a predicted urgent low. Use quiet hours, snooze, sound, and repeat controls to decide how and when RangeTrace gets your attention.

Choose which details appear beside the clock and where range colors are used. RangeTrace supports both mg/dL and mmol/L and adapts to light and dark mode.

Use the Current Glucose action in Apple Shortcuts or search for it with Spotlight. Get a compact result based on the latest reading saved on your Mac.

RangeTrace stores Dexcom credentials in the macOS Keychain. Readings and preferences stay on your Mac, with no separate RangeTrace account, advertising, analytics, or tracking.
