iLet Bionic Pancreas

The iLet Bionic Pancreas from Beta Bionics represents 2025's most innovative fully automatic insulin pump for Type 1 diabetes – no carb counting required! Based on weight and CGM data from Dexcom G6/G7 or FreeStyle Libre 3 Plus sensors (durability 10–15 days), it adjusts insulin hourly, selects aggressive or conservative targets, and corrects automatically. As a tubed system weighing 110 grams at dimensions of 5.0 x 9.1 x 1.5 cm with 300 units capacity, it improves A1c and TIR up to 93% without traditional settings. The system offers maximum simplicity and is ideal for beginners, as no carb counting is required. The full closed-loop continuously learns patterns and works with targets from 110–140 mg/dL. The compact design and easy operation make it particularly user-friendly, while the integrated iCGM functionality ensures real-time data. The high TIR of up to 93% and fewer hypoglycemia significantly improve quality of life. However, the system works as a tubed tube system, which can be a limitation for some users. Occasional longer highs can occur, and the price is higher than other systems. Despite these aspects, the iLet convinces through its maximum simplicity and high TIR. Compared to other systems, the iLet shows particular similarity to the MiniMed 780G, as both prioritize automation and meal detection. While the 780G offers faster adjustments every 5 minutes, the iLet scores with fewer settings and no carb counting. The mylife YpsoPump also offers similar app-based learning ability but makes different compromises in automation.
