How it compares
Unlike traditional blood glucose monitors such as the Ascensia CONTOUR NEXT GEN or the OneTouch Verio, Stelo requires no finger pricks or test strips. It also competes with prescription-only CGMs like the Dexcom G7, but Stelo is available over the counter without a doctor's visit. The 15-day wear time is longer than most non-invasive alternatives, and the app provides actionable insights without complicated calibration.
What to know before buying
- Check that your smartphone is compatible with the Stelo app (iOS 15+ or Android 10+).
- Apply the sensor to the back of your upper arm and avoid areas with scars or tattoos.
- Allow 1 hour for sensor warm-up after initial activation.
- Sensors are water resistant, so you can shower and swim, but avoid submersion beyond 1 meter.
- Stelo is not intended for diabetes management without consulting a healthcare provider; it is a wellness device.
- The 2-pack covers 30 days; reorder before the last sensor expires to maintain continuous data.
