For patients who prefer Multiple Daily Injections (MDI) over wearable pumps, Smart Insulin Pens have become the standard of care in 2026. These devices look like traditional insulin pens but are equipped with Bluetooth connectivity and internal sensors.

Smart Pens automatically log the timing and size of every dose, transmitting the data to a smartphone app. This eliminates the need for manual logging and helps prevent "stacking"—a dangerous situation where a patient takes a second dose too soon because they forgot the first. In 2026, these pens also integrate with Continuous Glucose Monitors (CGM), allowing the app to suggest dose adjustments based on real-time sugar levels and active insulin on board.
