Why is Time In Range important?

Every 10% increase in Time In Range can lower A1c by 0.8%12.

Every extra hour in range has a positive impact on your glucose control13.

Spending more Time In Range can reduce long-term health complications14.

Guidelines recommend spending at least 70% of your Time In Range(70–180 mg/dL)13,15.

Automatically calculates the percentage of time you spend in, above and below the target range
