BUT, will you please change the long acting dose settings! Having it at a max of two doses a day is troublesome especially when there’s people like me who take long acting 3X a day ### 4/5 — Inpen app *2026-03-12, version 8.0.0* I love my Inpen and the app. I bought a new iPhone and the app didn’t transfer from old phone to the new phone. I can’t make contact, get an answer when I call the company about how to move and properly set the app up on new phone. I’m on hold forever waiting for a representative to answer my call! I need help to do this. Where is customer service technical support? Help me! ### 1/5 — Freezes and crashes *2026-02-14, version 8.0.0* InPen is amazing. The app used to be amazing. Over the past year with Medtronic it has gone to garbage. Now it constantly freezes,crashes and takes forever to load. This needs to be fixed. iPhone 17 with latest iOS. ### 1/5 — HEY! We need the widget asap! *2025-12-19, version 8.0.0* Update the app and support the Lock Screen widget! It’s not that hard. The data to sync to the widget is deterministic so it should be quite simple to do. Now for over a whole year you’ve ignored this most critical feature ### 5/5 — Great product *2025-10-13* Absolutely love my InPen!! Makes things so much easier when giving doses of insulin and I love how it calculates my dose. One thing I’d love to see changed is the dosing of long acting insulins. The app only gives you the option of two doses a per day, as I am given three doses per day, I’d love to see the option to have reminders for three times a day. But other then that I am extremely happy with this product and I will definitely continue using it for years to come ### 1/5 — We need the widget asap! *2025-10-10, version 8.0.0* Dexcom is forcing us to upgrade to iOS 18.5 by December 2025. This means we can no long stay on iOS 17 to keep the old inpen widget working. Update the app and support the Lock Screen widget! It’s not that hard. The data to sync to the widget is deterministic so it should be quite simple to do. Now a whole year you’ve ignored this most critical feature ### 4/5 — You broke it! *2025-08-13, version 8.0.0* The app isn’t perfect but the most recent update is terrible. I constantly get a pop up asking me to turn on e - which I already have on. The app gets stuck constantly!!! Also why can’t you make a complication for Apple Watch? ### 2/5 — Update is horrible *2025-08-04, version 8.0.0* The recent app update causes a notification to pop up every time you open the app and asks you to turn on notifications in the background. When you got to settings, that option is greyed out and doesn't work. What is worse is you get that pop up every time you open the app. Notifications were not broken so you mucked it up, s/w developers!! Update: contacted support and they stated they are aware of this glitch. They are supposedly going to issue another update but the phone rep did not know when. In the meanwhile, you have to keep ignoring the pop up and manually entering your long acting insulin. ### 3/5 — iOS 18 broke Widgets *2025-07-20, version 8.0.0* Widget for active insulin and access to calculator was was extremely valuable. Please update with new widget option for iOS 18. ### 1/5 — Horrible Customer Service *2025-07-19, version 8.0.0* They upgraded their software which cause a problem with recording doses. I spoke to THREE different reps to get help. ALL said the would look into and get back to me. Still can record my dose. You should be ashamed of yourself Medtronic. Don’t invest in this tool. It’s not worth the aggravation. ## Frequently asked questions about InPen Smart Pen ### What does the InPen app do?
