Tandem Mobi

The Tandem Mobi represents 2025's most compact tubed insulin pump and is a true game-changer for Type 1 diabetics seeking mobility and automation. As a smartphone-controlled system with Control-IQ+ technology, it predicts glucose 30 minutes ahead, automatically adjusts basal insulin, and delivers hourly auto-correction boluses – ideal for unpredictable days. With 300 units capacity, only 88 grams weight, and touchscreen-free app-based control, it's water-resistant and integrates Dexcom G6/G7 and FreeStyle Libre 2 Plus sensors (10–15 days). The ultra-light design at about 5 x 3 x 1 cm makes it the world's smallest tubed pump and improves quality of life through intelligent predictions. The automatic features include temp basal adjustments, special sleep and exercise modes, and AutoBolus for missed meals. The seamless Bluetooth connection and extended CGM compatibility ensure easy software upgrades and long battery life of up to 3 days. Users report up to 90% TIR and significantly fewer manual inputs. However, the tube can interfere with certain activities, and app dependency requires a smartphone. As a newer system on the market, there are fewer long-term data compared to established models. Despite these aspects, the Mobi convinces through its intelligent modes for different situations and compact design. Compared to other systems, the Tandem Mobi shows particular similarity to the t:slim X2, as both come from the same company and offer identical Control-IQ+ features. While the Mobi is smaller and lighter than the X2, the X2 scores with integrated touchscreen instead of app control. The Omnipod 5 also offers similar compactness and prediction capability but works as a tubeless system.
