Tandem t:slim Mobile App Now Authorized by Health Canada for iPhone and Android Phones

via Business Wire

Tandem Diabetes Care, Inc. (Nasdaq: TNDM), a leading insulin delivery and diabetes technology company, today announced Health Canada authorization for distribution of the Tandem t:slim mobile application for Android and iPhone users. The Tandem t:slim mobile app allows users to deliver a bolus from their compatible smartphone, and to wirelessly upload their pump data to the cloud-based Tandem Source platform.1 The app is expected to be available later this year.

“This authorization demonstrates our dedication to expanding Tandem’s global offerings and delivering advanced technology to our Canadian customers,” said John Sheridan, president and chief executive officer. “It showcases our team’s agility in meeting international standards and our commitment to offering innovative, integrated diabetes solutions.”

The Tandem t:slim mobile app is a secure, user-friendly mobile application that, when paired with a t:slim X2 insulin pump, displays the user’s pump information on their personal smartphone. In addition to the ability to deliver and cancel a bolus, the mobile app displays the last 24 hours of glucose trends, pump status changes, and insulin therapy data, including basal and bolus deliveries and suspensions of insulin delivery. The app also displays pump alerts and alarms, and it securely uploads data into the cloud-based Tandem Source platform wirelessly. Importantly, the t:slim X2 insulin pump functions independently from the Tandem t:slim mobile app, therefore a user always retains the freedom to view pump therapy data, program requests and cancel or stop bolus insulin requests from their pump.

The Tandem t:slim mobile app will be available for compatible smartphones in the Apple App Store and Google Play store later in 2025. Once available, Tandem will email eligible customers with instructions on how to download and use the app.

The information on the t:slim mobile app display may not be identical to the current status of the user’s pump. Wireless uploads from the t:slim mobile app to the cloud-based Tandem Source platform require a compatible phone and an internet or wireless data connection. Uploads to the Tandem Source platform do not take place in real time and should not be relied upon by healthcare providers or caregivers for remote patient monitoring. Standard carrier data rates may apply.
