👀 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.
Daily CV
Daily glucose variability. A value below 36% is generally desirable.
days: 14
avg CV: 40%
Δ: +13%
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.
days: 14
avg SD: 2.9
Δ: +1.0 mmol/L
📸 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 53.8 g carbs per meal.
Prebolus used: 75% of meals.
Worth checking: meals with 50+ g carbs — 23 (42%).

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: 12 scenarios without a notable peak.
Peak above 10.0: 38 scenarios at approximately 2 hours.
Late rise: 10 scenarios where glucose at 120 min rose noticeably more than at 60 min.
