Sequel twiist

The Sequel twiist represents 2025's latest AID pump for Type 1 diabetes and convinces with unique acoustic technology for precise dosing. As a tubed system weighing about 80g, it holds 300 units and predicts 6 hours ahead, adjusts every 5 minutes, and detects blockages automatically. Compatibility with Dexcom G6/G7 sensors (durability 10–15 days) and targets from 87 mg/dL enable control via iPhone/Apple Watch and significantly improve TIR. The high precision through acoustic technology and accuracy with air bubble detection make the system particularly attractive for users who value precise dosing. Real-time volume measurement, blockage alarms, and personalized loop functionality via Tidepool ensure optimal control. As the smallest pump with 300 units and water-resistant design, it offers versatile control over iPhone and Apple Watch. However, the system is new to the market, which means less long-term data. As a tubed tube system, it can be a limitation for some users, and the relatively high price should be considered in the decision. Despite these aspects, the twiist convinces through its innovative technology and high precision. Compared to other systems, the Sequel twiist shows particular similarity to the Tandem Mobi, as both are small, tubed, and work with Dexcom and strong prediction capabilities. While the twiist is more precise through acoustic technology, the Mobi scores through its more established position and lower price. The iLet also offers similar automation and control but makes different compromises in technology.
