Tandem launches t:slim mobile app in Canada

Tandem Diabetes Care (Nasdaq:TNDM) announced today that it launched its t:slim mobile application for Android and iOS users in Canada.

San Diego-based Tandem’s t:slim mobile app connects to the company’s t:slim X2 automated insulin delivery system. It enables users to deliver a bolus from their compatible smartphone. They can also wirelessly upload pump data to the cloud-based Tandem Source platform.

Tandem — one of the largest diabetes tech companies in the world — received Health Canada authorization for the mobile app in September. It says its app offers a secure, user-friendly interface that displays pump information on a personal smartphone. In addition to bolus delivery and cancellation capabilities, it displays the last 24 hours of glucose trends, pump status changes and insulin therapy data. That includes basal and bolus deliveries as well as suspensions of insulin delivery.

Read more about Tandem and its recent developments, including other mobile app advancements in a recent Drug Delivery Business News interview with Director of Product Marketing, Ben Mar.

Additionally, the app displays pump alerts and alarms and securely uploads data into the cloud-based Tandem Source platform wirelessly. Tandem says the t:slim X2 pump still functions independently from the app. This allows the user the freedom to view pump therapy data, program requests and cancel or stop bolus insulin requests from their pump.

The t:slim mobile app is now available for download in the Apple App Store and Google Play Store. Eligible customers will receive an email with instructions to download and use the app. Users must be on the t:slim X2 pump version 7.8.1 or above to pair the pump with a compatible smartphone and use the app.

“With this release, we are furthering our commitment to expand our innovative, integrated solutions to customers worldwide,” said John Sheridan, president and chief executive officer. “We are thrilled to be able to bring the benefits of the Tandem t:slim mobile app to our customers in Canada for both iOS and Android devices.”
