Tandem Device Updater


Innovation delivered in real time

The Tandem Device Updater is a Mac® and PC-compatible application  for the remote update of Tandem insulin pump software. It provides our customers access to new and enhanced features faster than the industry has been able to in the past.

Touchscreen Technology

Insulin delivery will be revolutionized by advancements in software – the instructions that tell your pump how to respond. Because Tandem’s pump buttons are touchscreen controls that respond the way software instructs them to, you’ll be able to take advantage of future innovation with a simple software download.1




Immediate Pump Updates   

The first use of the Tandem Device Updater is the deployment of the latest t:slim® Insulin Pump software to t:slim Pumps purchased before April 2015. This software, updated based on customer and healthcare provider feedback, includes an expansion of the reverse correction functionality, the ability to enter a manual bolus directly in the suggested bolus window, off-pump cartridge filling, and other features that enhance convenience and flexibility.

Am I Eligible to Update?

The current update is available to customers with the original t:slim Pump software. The updated software that shipped on or after April 2015 uses on-screen buttons with square corners. The original t:slim Pump software, shipped before April 2015, displays rounded corners. If your pump screen’s buttons have rounded corners like the "Original t:slim Pump" images shown here, this update is for you. Please see the System Requirements below for a list of minimum computer and software requirements needed to install and run the Tandem Device Updater.
