Dexcom G7 – Accurate, But Requires Prescription & App Learning Curve
  • 10-Day Wear Sensor
  • Real-Time Data via Smartphone
  • Alerts for Hypo/Hyperglycemia
  • Auto Data Sharing with Doctors
  • High Accuracy Readings
  • Slim Sensor Profile
  • Requires prescription
  • Complicated app interface for beginners
  • Can trigger skin irritation for sensitive users
  • Not waterproof for full immersion
⚠️ Downside: Dexcom G7 is a solid performer in clinical settings, but it’s not beginner-friendly and lacks the simplicity of BloodVitals. Between app bloat and short 10-day wear time, it falls short in day-to-day convenience.

  • Optional Alarms with App
  • Good Accuracy
  • Easy to Apply
  • Requires manual scanning to check readings
  • No real-time continuous alerts
  • No full water resistance
  • Bluetooth pairing issues reported
⚠️ Downside: While affordable and accurate, FreeStyle Libre 2 still feels stuck in the past. Needing to manually scan every time limits its effectiveness—and in emergencies, those few seconds can matter. BloodVitals CM updates in real time—no scan needed.

  • Bluetooth Data Sync
  • High Accuracy
  • Long-Term Glucose Trends

  • Invasive for first-time CGM users
⚠️ Downside: Eversense is impressive on paper, but it’s not for the faint of heart. The implant procedure and high cost make it a niche option. For most users, BloodVitals CM offers all the key benefits—without a scalpel or surgery.
