By Dr. Sarah Mitchell, Respiratory Equipment Specialist · Published 2026-06-03 · 8 min read
Beta Bionics iLet eliminates carb counting. Users just enter their weight. Real-world TIR results are extraordinary.
Type-1 Diabetes Without Math
The Beta Bionics iLet is the first FDA-approved insulin pump that requires only the user's weight — no carb counts, no correction doses.
How It Works
- Pairs with Dexcom G7 or Libre 3+
- Algorithm adjusts every 5 minutes based on CGM trend
- User taps "small/medium/large meal" — pump handles the rest
Real-World Results (2026 registry data)
- Time-in-range (70-180): 72% average
- Hypo time (<70): 1.4% (target <4%)
- A1c reduction: 0.7% in first 6 months
vs Tandem Control-IQ and Omnipod 5
- iLet wins on simplicity
- Tandem wins on customization
- Omnipod wins on tubeless
Coverage
Medicare and most commercial plans now cover iLet for type-1 and select type-2 (insulin-dependent) diabetes.
