👀 Demo data

The upper graphs and main metrics use the demo data source. The After meals and Confirmed meals sections below also use actual meal records from that demo source.

Daily TIR

Percentage of time in the 3.9–10.0 mmol/L target range for each day.

TIR Average glucose

days: 14

avg TIR: 70%

Δ: Δ 30 days -58%

Daily CV

Daily glucose variability. A value below 36% is generally desirable.

CV Below/in range/above

Daily SD

SD is the spread of glucose values within a day. Lower SD means a more stable day. The graph background indicates approximate zones: good — up to 2.0 mmol/L, moderate — 2.0–3.0 mmol/L, high — above 3.0 mmol/L. Aim for a lower SD without increasing hypoglycemia.

📸 Confirmed meals

Shows the latest 24 confirmed photo meals in the selected period and evaluates the outcome using CGM data over approximately the next 2 hours.

Meals and calculation

This section is based on meal_events for the selected period. These are actual meal-calculation events, including meals where no photo was used.

Typical meal: about 49.5 g carbs per meal.

Prebolus used: 73% of meals.

Worth checking: meals with 50+ g carbs — 21 (43%).

The demo below shows photo-based meal examples, meal history and visual outcome summaries.

After meal

Evaluation based on meal_events and CGM data cached by Dia.best. Shows what happened approximately 60 and 120 minutes after the meal.

Stable outcome: 16 scenarios without a notable peak.

Peak above 10.0: 27 scenarios at approximately 2 hours.

Late rise: 8 scenarios where glucose at 120 min rose noticeably more than at 60 min.
