Has potential

It works well in general. It needs extended bolus and exercise mode activation.

Great App

Love this app, everyone should use it, very good! I would like to see it also have extended bolus function and activity function added to it in Canada.

I need help

It says it connected but when I try and since my data and actually use the pp it won’t let me , I’ve tried everything that the doctors and website had told me to do, it says it is a technical issue error

Pump Real-time Data??

Your competition has near realtime pump, insulin data telemetry; how about a caregiver app that lets us help our kids maintain sites, pump battery, insulin levels… y’all are so slow on features 😑

Great app

Great app for my pump although one major downside is it is missing extended bolus and it would be amazing if they added a Apple watch app
.

Just needs a widget

I love having the option to bolus from my phone. Would be nice if more pump features were available in the app. A widget that I could add to my Home Screen to show my glucose with the directional arrow would be innovative. I can see the remaining fuel and mileage I can travel in my car with a widget, and having the option to add my blood sugar reading on my phone screen would be a game changer. Please share with your developers.

The Software

Is there a way that you the builders of the app can help improve the experience of this app on IOS 27 software? Because I’ve tried to use the insulin pump amount function and it doesn’t work and I’m getting a new iPhone tomorrow and would like to be ready as soon as possible. Pls and thank you

Genuinely impressed

Works super well and there is almost no delay when bolusing.

It seems to reconnect to the pump everytime I open the app but it take about 5 seconds so I don't mind it.

One suggestion would be to have the bg numbers appear higher or lower instead of directly on the dots of the graph. As it is now its hard to see the tendency as the green "star" covers multiple dots especially if you checked it multiple times.

Yes

I like the app but would REALLY like to be able to see the date/time the cartridge was last changed like you can see when your CGM was last changed please! It would be so much more convenient than it is now to have to go into the pump and go through a bunch of screens to see when you last replaced the cartridge.

More customization

I just started an insulin pump, as a diabetic which is super cool! But the lack of features like setting your exercise or sleep schedule, or even turning on dark mode from inside the app is SUPER ANNOYING! I went with the X2 /specifically/ because I wouldn’t have to change it as often which is great but the fact that I have to activate sleep mode from the pump itself gets me annoyed. I shouldn’t have to dig my pump out from wherever I have it to activate sleep mode just so I can SLEEP! MOBI users get to active sleep and exercise from their app so why can’t X2 users? And NO, I don’t want to talk to anyone from the tech team tandem, I want you to update the app to have these features because I know you can!

Update: App QoL updates can include a built in calculator like the pump itself has and a way to activate activities from the app w/o needing to unlock the pump. Again, I don’t want to talk to the tech team, I want you to bring this review directly to them and ask “Is this possible for our diabetic patients?”

Terrible

Randomly stopped accepting my libre 2 plus sensors with no prior warning and didn’t let me update the pump before to use the libre 3 plus sensor. Absolutely criminal. Now I’m stuck with a libre 2 plus sensor that won’t work. What a terrible company and product. Switching to another company and product asap. Unbelievable.

Stop telling me to verify my time

Seriously stop sending me the damn "Verify the time on your pump" notification, it's the right time off by ONE MINUTE, like goddamn make it so it detects like a 5 minute gap instead or a 2 minute gap.

Sandysanjon

It stinks. Half the time it loses connection and when that happens it won’t give you the basil dose. Not reliable

Request for notes option

I really wish there was a way to add time stamped notes in the app, especially regarding blood glucose readings compared to my CGM.

Poor Software

This app does not let you zoom in on features to view the graph. It basically just shows you if you are over or under your target number

Lame

The only thing this app is good for is a bolus. Tandem needs to add the ability to do pretty much everything you can do on the pump with the app. Should be able to stop insulin to jump in the shower, change the personal profile and so much more. The app hasn’t received any major improvements in the many years I have been using it. I am going to be looking at the competition very seriously when I get close to being out of warranty and eligible for a new pump. Great pump but Tandem hasn’t kept up.

App update

Great experience. Would it be possible in iOS 27 to ask Siri to give me a bolus or change activity mode? That would be very helpful. Thanks for a great product.

Very hit and miss

Hasn’t worked for over 2 weeks now. Says “make sure the pump and phone are near each other”… I have put my pump and phone literally on top of each other and doesn’t work. Very annoying

17 pro max incompatible

Bolus feature not available on 17 pro max apple. Always loses connection. Useless

Always disconnecting

Constantly disconnects from my insulin pump
