The t:connect mobile app, designed for Android devices, serves as a companion for the t:slim X2 insulin pump. This free lifestyle application enhances user experience by allowing users to deliver boluses directly from their smartphones. It acts as a secondary display for the pump, providing easy access to pump data and notifications, making diabetes management more convenient and discreet.

Users can wirelessly upload therapy data to the cloud, ensuring that all relevant information is stored and accessible. The app supports multiple languages based on the smartphone settings, enhancing usability for a diverse range of users. While it offers significant functionality, it is important to note that alerts and alarms must be managed directly on the pump, maintaining a direct line of communication for safety and reliability.
