PEER REVIEWED

The OneTouch Verio Flex is designed for simplicity. Its defining feature is the ColorSure Dynamic Range Indicator, which displays a color-blue (low), green (in range), or red (high)-along with the numerical result. This provides immediate context, which is especially helpful for newly diagnosed patients. The meter itself is slim and portable, with a basic screen and just two buttons. It syncs via Bluetooth to the OneTouch Reveal app, which is functional for tracking and spotting trends, though less feature-rich than competing apps. Our accuracy tests found it to be reliable for everyday monitoring, though it requires a slightly larger blood sample than some other modern meters. For those seeking an uncomplicated entry into smart glucose monitoring, the Verio Flex is a solid and dependable option.
