Time in Range Calculator
Calculate your Time in Range percentage from glucose readings. Analyze diabetes management and get personalized insights for better glycemic control.
Step 1: Glucose Readings
More readings provide more accurate Time in Range calculation. CGM data with 14+ days is recommended.
About Glucose Readings
Time in Range (TIR) is the percentage of time spent in the target glucose range (usually 70-180 mg/dL). Higher TIR indicates better diabetes management.
Step 2: Target Range
Clinical Targets
For most people with diabetes, the goal is >70% Time in Range (70-180 mg/dL), <4% Time Below Range (<70 mg/dL), and <25% Time Above Range (>180 mg/dL).

Range Interpretation
Clinical guidelines recommend aiming for >70% Time in Range, <4% Time Below Range, and <25% Time Above Range. Use this data to adjust medication, diet, or activity.

Personalized Recommendations
Based on your Time in Range of 68%
Consider reviewing your mealtime insulin doses or carbohydrate counting accuracy. Monitor post-meal glucose spikes and consider adjusting pre-meal insulin timing. Discuss these results with your healthcare team.
