Tandem launches t:slim mobile app in trio of European countries

Tandem Diabetes Care (Nasdaq:TNDM) announced today that it made its t:slim mobile app available in a handful of new European countries.

The company said on LinkedIn via its International account that it made the app available on both Android and iOS in Germany, Belgium and the Netherlands.

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 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.

Additionally, 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.

This launch marks the latest milestone for the company’s automated insulin delivery technology. President and CEO John Sheridan recently outlined the plans for Mobi Tubeless, the company’s existing Mobi pump that utilizes a novel infusion set option for tubeless insulin delivery.

Other recent milestones include the launch of a pay-as-you-go reimbursement model in the U.S. pharmacy channel, the launch of a new Mobi app for Android, and the pricing of an upsized offering worth $265 million.

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.
