1. 3/5Convenient but annoying

   I want to start this review off by saying that the Tandem Mobi itself is amazing and makes injecting insulin and keeping track of blood sugar so much easier and more convenient. The problems come in when you look at the app itself, more specifically when it comes to the alerts. This thing will non stop spam you with loud beeps and buzzing and there is nothing you can do to stop it. You can turn off the beeps at least but that infuriating buzzing will never stop no matter what you do. I understand some of these alerts are important, but a lot of the time it will keep repeating the same alerts over and over and over again despite you having cleared them and it gets old very fast. Not to mention other design flaws such as the fact that that when you manually stop insulin flow, THE APP WILL BEEP AND BUZZ AT YOU AFTER A CERTAIN AMOUNT OF TIME. This is beyond stupid, as there are many instances where you need the mobi to be off of your body for a long period of time and you obviously need to stop the insulin flow so it doesn’t leak and waste insulin but this stupid thing will not stop bothering you. This happens a lot when you try to charge it, because for some reason the people who programmed it didn’t have the foresight to turn off the buzzing while it’s literally charging. I ran out of supplies for new pumps and so I haven’t been able to connect it to my body and since this app is poorly thought out and poorly programmed, I had to manually make a new profile and set the basal rate to 0. There should just be a button that lets me fully shut the pump down in cases such as this, because it is absurd that I have to jump through all these hoops just so I don’t get kept up at night by buzzing every 5 minutes.

2. 3/5Core app is good but notifications need more options

   I have this app and the dexcom app installed. Which means everytime I go low or high I receive like 4 notifications. I would love to delete the dexcom one so I don’t get spammed as much but I can’t because this app doesn’t let you customize the notification noises at all. The only options are vibrate and beep. I am a heavy sleeper so I need the dexcom apps notifications to wake me up cus this app has very quiet notifications and I’d rather not die in my sleep from being low. But it’s also really annoying cus clearing the notifications when I’m already irritable from being low is terrible. Also the only way to stop the beeps for this app is to go to notifications and swipe to the side and delete it. I don’t know why there’s not just an acknowledge button that pops up similar to the dexcom app. Again the rest of the app I like. The stats main screen is great but everything related to notifications is terrible.

3. 1/5Has 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.

4. 1/5Infuriating design choices

   I use this pump because it’s what my insurance covers and it’s what I have, but the alarm system on this thing makes me wish I didn’t have to. There are two high alarms when control IQ is on, BUT the second one always goes off after a genuinely random amount of time, so if I wake up in the middle of the night to a high alarm, I have to wait an indiscernible amount of time for the second one to go off. This problem has brought me to the point where I sometimes just been sleep without my pump, which I know is dangerous and not sustainable long-term, but I also have to rest well at some point. Additionally, the “find Paired Pump” alarm used to be really loud, but after a software update in ‘24 or ‘25, it became the QUIETEST sound this pump makes. I’d love to talk to whoever made that decision because why is the seeking noise the QUIETEST sound the pump is capable of?!? It USED to be loud!!! Why did we change that?! Just some super strange design choices I am BEGGING you guys to change: make the Control IQ high alarm go off at a consistent time after the first high alarm and please make the find my Paired Pump alarm louder

5. 3/5Need timers

   This has a few very basic shortcomings, mainly the lack of timers. I exercise daily and change my profile to lower my basal and corrections. There needs to be functionality added to set a timer for a profile change as I am prone to leave that on for hours, only to realize it when I enter a correction and the amount is clearly too low. The fact of the profile change is also very subtly displayed on the Home Screen; a different colored bar across the top would be a more apt alert. In addition, the algorithm on exercising needs work as it over delivers insulin during it. Lastly the graph is not very helpful. It has a huge range and you can’t zoom in nor see the detail unless you’re on a computer. I’m often in range and want to see what my BG is when there are changes, but the “in range” part of the graph is less than 25% of the graph.
