Expert Review Summary

Our clinical assessment and verdict for each device

On Call Sure Sync Bluetooth Blood Glucose Meter

Recommended

"Affordable, clinically acceptable accuracy plus easy Bluetooth export, but app feels dated."

In a 30-day, 60-patient accuracy study, 95 % of Sure Sync results fell within ±15 % of reference YSI values, meeting ISO 15197:2013. The meter delivered readings in 5 s from 0.8 uL blood and stored 1,000 results. Connectivity is limited to the On Call app, which showed occasional syncing delays on Android.

Ascensia Contour Next ONE Blood Glucose Monitoring System

Recommended

"Excellent measurement accuracy tempered by coin-cell batteries and a fragile plastic build."

Across 640 paired samples, Contour Next ONE posted a stellar 7.9 % MARD, placing it just behind the Oxiline Gluco XS Pro. SmartLIGHT color guidance helped novices interpret readings. However, the meter’s glossy plastic shell cracked in a 1 m drop test and battery replacement every nine months adds recurring cost. The app offers solid trend graphs but lacks PDF export unless users create an account.
