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. ### 5/5 — Awesome!!!!! Love the pump. *2026-07-30, version 3.6.2* 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!❤️ ### 4/5 — Great pump but… *2026-07-28, version 3.6.2* 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. ### 3/5 — Wait Until the Next Version *2026-07-25, version 3.6.2* 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. ### 3/5 — Need update *2026-07-18, version 3.6.2* 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 ### 1/5 — BEWARE you need two apps *2026-07-17, version 3.6.2* 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. ### 2/5 — Battery *2026-07-16, version 3.6.2* 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 ### 4/5 — Love the Smaller Insulin Pump *2026-07-12, version 3.5.2* 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. ### 3/5 — It’s great but I’m giving a picky review *2026-07-11, version 3.5.2* 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 🙏 ### 5/5 — Awesome! *2026-07-08, version 3.5.2* Best pump app ever!!! I feel so much better now that I have tandem!
