Coming Soon!

Enjoy the freedom to bolus directly from your smartphone

Mobile App

Give yourself the freedom to more easily manage your diabetes with the t:slim X2 insulin pump and t:connect mobile app

With this much-anticipated feature, expected summer 2022,* you'll have the freedom to bolus without having to touch your t:slim X2 insulin pump. That increased flexibility decreases how often you need to interact with your pump.


Enjoy the Freedom to See Clearly

Conveniently view your pump data, including basal and bolus events, pump and sensor status, insulin on board, carbs, and settings on your compatible smartphone.


Enjoy the Freedom to be Discreet

Serving as a secondary display for your t:slim X2 insulin pump, the t:connect mobile app allows you to view alerts from your pump as push notifications.
