Explore the features of the t:connect mobile app

Your patients can conveniently view their pump data, including basal and bolus insulin events, insulin on board, carbs, settings, and both pump and sensor status directly on their smartphone with the t:connect mobile app.

Getting started

Patients must download the app on their phone and then pair the app with their insulin pump. Here are the steps to follow:

  1. Download Free Mobile App

  2. Visit Google Play or the App Store, search for “Tandem Diabetes” and select “t:connect mobile” from the results.

  3. Turn on Mobile Connection

  4. Unlock the pump, tap OPTIONS, Device Settings, and then select Bluetooth® Settings. Tap the toggle to turn on the Mobile Connection and enable Bluetooth.

    NOTE: If your patient doesn’t see Bluetooth Settings, they can visit the Customer Portal to update their pump to the latest software (they may need a prescription and training).

  5. Login to Mobile App

  6. Use a t:connect web application username and password (or create a login and password in the t:connect mobile app).

  1. Pair Insulin Pump to Mobile App

  2. Follow the prompts to pair the pump with a phone. For detailed pairing instructions, visit our Quick Reference guide. Only one device can be paired with the t:connect mobile app at a time.

    NOTE: We strongly suggest patients upload pump data to the t:connect web application via USB cable before pairing their phone. After they’ve synced their pump to the app, the data will upload to their t:connect account. This can take minutes, hours or days depending on when the patient last uploaded and how much data is stored on their pump.

*Bolus delivery from the t:connect mobile app requires a compatible smartphone model and operating system, an app update, a remote software update on the user’s t:slim X2 insulin pump and additional training. Only available to customers who reside in the United States.
The information on the t:connect mobile app display may not be identical to the current status of the user’s pump. Wireless uploads from the t:connect mobile app to the cloud-based t:connect web application require a compatible phone and an internet or wireless data connection. Uploads to the t:connect web application 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.
†† You cannot dismiss alerts and alarms from the app and must do so on the pump itself, but once an alert or alarm has been dismissed on the pump it will immediately disappear from the mobile app

Important Safety Information

RX ONLY. The t:slim X2 pump and Control-IQ technology are intended for single patient use. The t:slim X2 pump and Control-IQ technology are indicated for use with U-100 insulin only.

t:slim X2 insulin pump : The t:slim X2 insulin pump with interoperable technology is an alternate controller enabled (ACE) pump that is intended for the subcutaneous delivery of insulin, at set and variable rates, for the management of diabetes mellitus in people requiring insulin. The pump is able to reliably and securely communicate with compatible, digitally connected devices, including automated insulin dosing software, to receive, execute, and confirm commands from these devices. The t:slim X2 pump is indicated for use in individuals six years of age and greater. Control-IQ technology: Control-IQ technology is intended for use with a compatible integrated continuous glucose monitor (iCGM, sold separately) and ACE pump to automatically increase, decrease, and suspend delivery of basal insulin based on iCGM readings and predicted glucose values. It can also deliver correction boluses when the glucose value is predicted to exceed a predefined threshold. Control-IQ technology is intended for the management of Type 1 diabetes mellitus in persons six years of age and greater.

WARNING: Control-IQ technology should not be used by anyone under the age of six years old. It should also not be used in patients who require less than 10 units of insulin per day or who weigh less than 55 pounds.

Control-IQ technology is not indicated for use in pregnant women, people on dialysis, or critically ill patients. Do not use Control-IQ technology if using hydroxyurea. Users of the t:slim X2 pump and Control-IQ technology must: use the insulin pump, CGM, and all other system components in accordance with their respective instructions for use; test blood glucose levels as recommended by their healthcare provider; demonstrate adequate carb-counting skills; maintain sufficient diabetes self-care skills; see healthcare provider(s) regularly; and have adequate vision and/or hearing to recognize all functions of the pump, including alerts, alarms, and reminders. The t:slim X2 pump, transmitter, and sensor must be removed before MRI, CT, or diathermy treatment. Visit for additional important safety information.

t:connect mobile app: The t:connect mobile app is intended to be a secondary display for compatible Tandem Diabetes Care insulin pumps and is capable of wirelessly uploading pump data it receives into the t:connect web application. The t:connect mobile app is not intended to control an insulin pump and is not intended to be a replacement for the information displayed on your insulin pump. Dosing decisions should not be made based on the secondary display device. The user should follow instructions on the continuous glucose monitoring system and insulin pump. This secondary display device is not intended to replace self-monitoring practices as advised by a physician.
