It helps avoid surprises by providing instant alerts on your phone, making daily management simpler and safer for kids or adults needing constant monitoring.
Who should use the Freestyle Libre 3 Plus over the 2 Plus, considering different diabetes types?
Type 1 diabetics or those on intensive insulin therapy should choose the 3 Plus for its automatic real-time readings and better accuracy, reducing hypo/hyper risks. Type 2 diabetics with stable control might stick with the 2 Plus, but upgrade to 3 Plus if you want a smaller sensor and no-scan convenience for easier tracking.
How do I choose between the Freestyle Libre 2 Plus and the Freestyle Libre 3 Plus for my diabetes management?
Pick the 3 Plus if you value automatic glucose updates every minute without scanning and a tiny sensor for comfort during activities or sleep. Go for the 2 Plus if you’re budget-conscious or prefer manual scans, but both offer 15-day wear and pump integration—check what fits your routine best.
What are the main differences between the Freestyle Libre 2 Plus and the Freestyle Libre 3 Plus?
The 3 Plus provides continuous real-time glucose readings via Bluetooth without scanning, plus a smaller, more accurate sensor for discreet wear. The 2 Plus requires manual scans for data, has a larger sensor, and slightly lower accuracy, but both last 15 days and work with insulin pumps.

Why should I consider upgrading from Freestyle Libre 2 Plus to Freestyle Libre 3 Plus?
Upgrade for the hassle-free automatic readings every minute and a smaller sensor that’s easier to wear without noticing it during daily life. You’ll get better accuracy and real-time alerts, reducing finger pricks and helping catch glucose swings early for improved control.
What new features does the Libre 3 Plus offer that the Libre 2 Plus does not?
It delivers continuous glucose data straight to your phone without scanning, plus superior accuracy with a lower MARD (around 7.9% vs. 8.2%). The tinier size makes it more comfortable and discreet, while still sharing 15-day wear and pump compatibility with the 2 Plus.
How does the accuracy of the Libre 3 Plus compare to the Libre 2 Plus in real-world use?
The Libre 3 Plus is more accurate in daily scenarios, with a MARD of about 7.9% meaning closer alignment to actual blood glucose levels during meals or exercise. The 2 Plus has a slightly higher MARD around 8.2%, but both are reliable—users report the 3 Plus feels more precise for avoiding false alarms.
When should someone consider switching from Dexcom G7 to Stelo, or vice versa?
Switch to Stelo from G7 if you’re off insulin, want to save money, and prefer fewer features for basic tracking without alerts. Consider G7 from Stelo if you start insulin, need real-time alarms for lows/highs, or want integration with pumps for tighter control.
