Love my Mobi

It’s so easy to fall in love with my pump. I love wearing it and control IQ is working its magic most of the time. My last A1C was 6.8 in April. This is my best pump so far.
I’m eating 2 meals a day. I’m able to go out for a one hour walk on the beach every day with perfect nos most of the time. Night time nos are always perfect.
Will update my A1C when I have another one.
There is room for improvement but for a machine I gave it a 5 stars. Thank you.

Awesome!!!!! Love the pump.

I’ve been a T1 for 2 years now and the mobi has really helped me through my journey with diabetes. Just one thing though, can y’all make it so I can turn the alerts off? Because if I go to shots (like I do every other month) it won’t stop alerting me, especially at night. But it’s the best pump out there!❤️

Great pump but…

I love my Mobi. Been on it since 12/2025. I have had to have a few replacements (2 pump replacements) but that wasn’t too big of a deal. Stuff happens, I get it. My biggest complaint is the fact that the app logs me out ALL THE TIME. MULTIPLE times a day sometimes. I’ve updated the app and the pump software and it keeps happening. I don’t always have an opportunity to throw it on the charger to re-pair it to my pump. So that’s pretty frustrating. Otherwise, I do love the Mobi.

Wait Until the Next Version

Version 3.6.2 consumes more battery on the iPhone. Also, it is ‘buggy’. I would wait until Tandem does a patch update before downloading.

Need update

Needs places where you can add whether you’ve been sick so has that other symptoms like migraines? Or any other people think you can with the G7 app where you can add events of your daily life to compare to your highs or low blood sugar

BEWARE you need two apps

I have to have the Dexcom app as well as this app. This is supposed to function as Control IQ for better BG control but because your app loses range AAAAAAALLLLL the time it barely functions as this. The Dexcom App NEVER loses range. I would get with them and see why they’re so much better than you. Tandem needs to step it up. You obviously,once again, put out a pump that wasn’t ready.

Battery

1. Both mobi and t:slim have the same issue that my app drains my pump extremely quickly, causing me to have to redownload and connect.
2. Why does the Mobi, which is supposed to be an improvement, not have the same option to choose how long to disconnect for, up until an hour. I mean it goes off after 10 which isn’t enough to charge and isn’t even enough to shower and get dressed

Love the Smaller Insulin Pump

Love the smaller size insulin pump, love controlling everything from the cellphone.
A minor issue was that the old TSlim app was disabled as soon as the Mobi app was installed. Hence I lost insulin on board. Please allow for 5 hours overlap for running both apps. The TSlim alarms when insulin delivery is stopped, making it difficult to keep old pump around for the few hours history.

It’s great but I’m giving a picky review

The app works as expected, but I would love to have widget options, square & rectangle. I want to see my IOB at a glance. Also, not to be hateful but I saw someone’s Omnipod app & I liked the bolus UX/design way better. But please, the widget 🙏

Awesome!

Best pump app ever!!! I feel so much better now that I have tandem! Thank you mobi!!!

Convenient 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.

Good app

Overall the app is easy to use. It would be nice if you could see the main screen in a horizontal view like how the Dexcom app rotates.

Update for G7 15 Day

Love the app, can't wait for G7 15 Day support!

The alarm to put it back on…

Look I get that everything needs alarms to make sure you wake up and such and it’s not the volume or the sound that’s weird it’s that the alarm still goes off while it’s charging. Like the alarm it gives telling you to put it back I ?if it’s on the charger OBVIOUSLY i don’t just have it off for no reason. I just think if it’s charging the alarm shouldn’t go off but if it’s not charging and it’s off then yeah let it go off.

Mobi

Slow to update anything. Needs more updates at in a quicker time frame and offer newer options sooner rather than later. While I love Mobi for its size it sucks with updates!

Give us a silent mode. And let us fill our tubing without stopping.

All in all I’m happy with the app. But please for the love of god give us the ability to shut the pump up. Not just vibrate, but a complete silent mode. Also, having to acknowledge yes or no if insulin has come out of the tubing when doing a site change is so unnecessary.

Graph visibility

Graph of bg needs enhancement. Green dots are hard to see they are so pale in color. Black dots would show up much better— or dark green.

An ok app with glaring omissions

This app is generally fine. It generally works consistently and includes most of the important functions it needs to: flexible boluses, temp basal rates, multiple profiles, etc. The pump itself can barely hold a bluetooth connection to the CGM and that should be an embarrassment to Tandem, but that’s separate from the issues with the app.

I’d really like to see the following changes to the app, and I’m not the only one, judging by the many reviews here, and discussion elsewhere online:

1. Implement a snooze function for alerts! This is basic, vital functionality. After I’ve been alerted my bg is out of range and I’ve treated the low/high, it is just useless harassment to force me to continue clearing staggered, redundant CGM and Control IQ alerts. It won’t make insulin or sugar take effect any faster, and it’s especially disruptive to sleep. Even a twenty minute “I’ve treated my high/low” option would be a huge relief, though I’d prefer a system like the G7 app, which lets me choose how long I want to silence alerts.
2. Stop Control IQ alerts when bg is already high/low, they’re 100% redundant in those times. Look: It’s valuable to be told I may go low in the near future, but it’s just infuriating to get ongoing, staggered alerts saying Control IQ has “predicted” I’m going to go low when its already happened.
3. Change the dashboard CGM graph to eliminate the periodic labels which cover up the readings! Especially when trying to make treatment decisions I want to see the last several values, and a spiky bubble that covers up what I want to know doesn’t help anything.
4. Lastly, and much lower priority: Maybe the pump doesn’t need to vibrate for in-app actions like clearing an alert, saving changes, etc? It’s already annoying to have it buzzing at me, I don’t need extra buzzes to tell me I’ve successfully addressed the cause of the buzzes.

I can imagine that those options might not be appropriate for every user to control - so put them behind a separate passcode or make them age restricted if need be. But it’s absurd for a responsible adult to not be able to snooze alerts. And PLEASE take these user requests seriously. Because of the nature of this app and our 24/7 dependency on it these things have huge impact on our quality of life.

Need to store pump settings in app

I like control iq. I don’t like the mobi. Since I’m averaging 2 pumps per year so far, it would be nice if the pump settings saved in the app to make replacement easier. It’d be even better to not need replacements but at least make this process easier. Otherwise the app is fine. I’m writing this after putting all my settings in a document in preparation for transferring to my second replacement/third mobi.

Vibration causes it to move off charger and makes too much noise

The vibration is super loud and there is no way to silence it. We already have alerts from the cgm so the vibration on the pump is extra and it burns the battery faster. It will not sit on the charger because when you stop insulin to charge it it vibrates nonstop and it moves off the charger.
