Colour-Coded Results System
The Verio Flex's standout feature is its colour-coded display: blue indicates a low result, green signals within-range, and red highlights a high reading. This visual feedback is especially valuable for older users, newly diagnosed patients, or anyone who benefits from an immediate, simple interpretation of their glucose level without manually comparing to target ranges.
Accuracy & Reliability
The meter meets ISO 15197:2013 standards, meaning 95% of results fall within ±15% of a laboratory reference value for glucose concentrations above 5.6 mmol/L, and within ±0.83 mmol/L for lower concentrations. Independent studies consistently rank the Verio Flex among the top performers in its price category. The no-coding design eliminates a common source of user error.
App Integration
Via Bluetooth, the Verio Flex pairs with the free OneTouch Reveal app (iOS and Android). The app displays 14-, 30-, and 90-day averages, pattern alerts, and meal-time breakdowns. Data can be shared directly with healthcare providers — a practical feature for remote diabetes management appointments.
