- Freedom to wirelessly upload pump therapy data to cloud

Note: Units of measure on app may differ from those pictured above. Mobile app units of measure will match the paired t:slim X2 insulin pump.

ALWAYS READ THE LABEL AND FOLLOW THE DIRECTIONS FOR USE.

The Tandem t:slim mobile app is an accessory intended for use as a connected software device that is able to reliably and securely communicate with compatible insulin pumps.

*Requires a t:slim X2 insulin pump from Tandem Diabetes Care and a compatible smartphone. Additional restrictions apply. Refer to the user guide for t:slim X2 insulin pump for a list of warnings and precautions.

†The information on the Tandem t:slim mobile app display may not be identical to the current status of your pump. Wireless uploads from the Tandem t:slim mobile app to the cloud-based Tandem Source platform require a compatible phone and an internet or wireless data connection. Uploads to the Tandem Source platform do not take place in real time and should not be relied upon by healthcare providers, pump users, 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 also disappear from the mobile app.

Ratings and reviews

I updated my phone once I received the email that my phone was now compatible, but after updating, the app no longer works even though all software is covered. Sad face. *Edit: about fifteen hours later, the app said I could do bolus delivery and it worked. *Edit: lots of disconnects with this version. I am turning my Bluetooth on and off several times a day for it to connect again.

It's nice when it works. It loses connection constantly and won't reconnect on its own, I have to force close the app and relaunch it for it to connect. This has just become a normal thing in order for me to use the app. Please make a dark mode. Having a solid white screen when delivering a bolus hurts the eyes when it's dark. Still seeing the same issues, but now the app is also draining my battery. It regularly accounts for 30% of discharge despite less than 10 minutes of screen time.

Since I've updated to Android 16, I am now experiencing constant disconnects from my pump. It's very easily fixed by turning Bluetooth off and right back on, but it shouldn't happen. This never happened for me until the OS update. Note that I do not talk on the phone for support. You should provide tech support via email as that's the only way I will communicate.
