Tandem Mobi introduces multiple innovative features and enhancements that set it apart from the current existing insulin pump options. Keep reading to discover more features about Tandem Mobi and how it differs from current automated insulin pumps.

Tandem Mobi Features

Some of the unique features of Tandem Mobi system includes:

IsTandem Mobi tubeless?

Tandem Mobi is not tubeless, but features a newly introduced 5-inch tubing designed specifically for this pump. Tandem Diabetes is working on a tubeless version of Tandem Mobi , but there are no details on a possible release date.

Is Tandem Mobi FDA approved?

Tandem Mobi received FDA clearance in July 2023 for people with diabetes aged 6 and up.

What’s the difference between TSlim X2 and Tandem Mobi?

While Tandem Mobi will utilize Control-IQ, the same automated technology that is used by the Tandem t:slim X2 along with a similar 200-unit insulin cartridge there are some notable differences between these insulin pumps including:

Size: Tandem Mobi significantly small than the t:slim X2 pump, fitting easily into a coin pocket or adhering to the body using a separately available adhesive sleeve.
Remote Insulin Delivery: Tandem Mobi lacks a built-in screen and relies on a compatible iPhone application for insulin delivery. In comparison, the t:slim X2 comes equipped with a screen for dosing or users can utilize the Tandem app for mobile dosing.
Tubing Options: When it comes to tubing options, Tandem Mobi users will have access to a shorter 5-inch tubing option in addition to over 30 existing infusion site and length options.

Individuals who purchase a new t:slim X2 between July 1 and December 31, 2023 may be eligible for the Tandem Choice Program which allows users to switch to the Tandem Mobi for $199 when it is available.

What’s the difference between Omnipod 5 and Tandem Mobi?

Tubing: Omnipod 5 is a tubeless insulin pod that doesn’t have any tubing. Tandem Mobi requires at least 5 inches of tubing for insulin delivery.
Automations: Omnipod 5 and Tandem Mobi have distinct automation algorithms and varying glucose target goals. Because Tandem Mobi incorporates Control IQ technology, its functionality will closely resemble that of the Tandem t:slim X2, which we previously compared to Omnipod 5.
Insulin Delivery: Omnipod 5 requires a separate mobile device for insulin delivery while Tandem Mobi users can utilize their compatible iPhone for mobile insulin dosing.
