Has potential but app is not ready for use

I was very excited for this insulin pump due to its small size and ability to be worn in different ways compared to the tslim x2. Unfortunately I think tandem has released this pump before it was ready to be used by people. While the small size of the pump is great, the app is not reliable which brings constant headaches to managing my diabetes. Connection will be lost between the app and the pump at least once a day, sometimes up to 10 times a day. The notifications are glitchy and inconsistent (sometimes they will not let you dismiss them or they will vibrate on the pump and not show on the app). The graph which shows blood sugars and daily time in range will only show and update ~20% of the time (sometimes closing and reopening the app will resolve this issue but sometimes it doesn’t). Tandem should not have released this pump before properly testing out the app. Due to the headaches of this app my time in range and A1c have both gotten worse compared to when I was on the tslim x2. I will probably switch back to injections over using this pump until tandem can resolve all of the issues with the app. But the small size of the pump is fantastic and that is the reason I will not consider switching back to the tslim x2.

No support for t:slim X2

This app does not support full control of the t:slim X2 from the phone app, nor does the t:connect app. If you guys are considering not giving us FULL control of OUR pumps (we own them, not you or the FDA) I suggest rethinking things.

While I’m at it, why don’t you guys work with the DIY community and make it easier for us to send commands to OUR pumps as we see fit, using whichever app whether DIY or slowly FDA approved, that we choose?

The t:slim X2 is my preferred pump (hardware-wise) to close the loop with via DIY APS apps, but it will not be possible until you guys release full control to the T1D community via an app update or share the communication protocols needed. My old Medtronic pump that gives me better glucose control thanks to having full radio control from DIY APS apps ain’t getting any younger while my X2 collects dust while I’m waiting for it to be unlocked. Please make our diabetic dreams come true by unlocking the full potential of out X2s before our old Medtronic pumps bite the dust! ❤️

fix your bad software

least customizable notification settings in the world, does not allow user autonomy over something that is CONSTANTLY ATTACHED TO THEM. there NEEDS to be a way to silence certain notifications. WHY is there no way to even put control IQ alerts on vibrate only at best???? control IQ alerts are also annoying and redudant given that it runs off of the user's CGM.... which gives them notifications but far, far far far less annoying because you can customize them. unlike the tandem mobi. additionally, there NEEDS. TO. BE. an easy to access place to see what phone update is compatible with the app if you're going to tell us during training that we can't update our phone unless the app is up to date, or else WE WILL NOT HAVE ACCESS TO OUR INSULIN PUMP. the user needs to know!!!!!!!!!! i haven't updated my phone since i got this pump. biggest mistake of my life.
