MEDTRONIC

Role: UX/UI Design & Content Strategy

Duration: Two Weeks

Audience: Type 1 Diabetics

Tools: Figma & Freeform

Introduction

Over 300,000 Canadians, including myself, live with type 1 diabetes. Effective management is crucial to prevent serious long-term complications like blindness, nerve damage, and more. An extensive list of tools exist to help with glucose control, in my experience, the MiniMed Mobile app is at the very bottom of that list. Frequent crashes, accessibility issues with data visualization, paired with limited functionality, create significant challenges.

In this case study, I redesigned the app, creating a more meaningful and user-friendly experience for individuals with diabetes. Check it out below 👇

What do People say about Medtronic?

Nothing great… the app’s got a 2/5 star rating on the App Store 😵‍💫

Review titled "Pretty basic software" with a 2-star rating. The reviewer, nowayanthony, comments that the app feels outdated and requests features for report viewing and real-time blood sugar display via a widget.
Review of pumps expressing dissatisfaction over lack of watch interface, widget, phone control, and app updates.
App review giving one-star rating with comment on March 5th by user 'ezabelle.' The review titled 'Useless' mentions issues with syncing data with CareLink and states the app only shows blood glucose levels.

I read reviews, got lost in Reddit rabbit holes, spoke to friends, and interviewed my diabetes team of doctors, nurses, and dietitians at St. Mike’s Hospital. Here are the learnings that stuck out 👉

App review titled "Like the app, needs notes capability" with four out of five stars. Review mentions desire for note-taking features for tracking exercise and bolus occlusion.
Negative iPhone app review complaining about app malfunction after iOS 16 update, user mention of Medtronic.
One-star app review titled "Garbage" by user Swimmswimmswimm, stating frustration with a pump app's connectivity issues, wishing to rate 0 out of 5.
One-star review by MarieL222 stating, "If I could give it 0 stars I would."

Key Findings

  • Users want a discreet and convenient way to give themselves insulin straight from the application, removing the need to take out and consult their insulin pump.

  • Users desire visual improvements to the app to enhance usability and enjoyment, emphasizing that these changes don't need to be radical, but should improve the overall aesthetic.

  • Text is too small, icons are confusing, and the graphs… don’t get me started on the graphs (this one’s personal). Deciphering hieroglyphics might be an easier job.

What’s gotta Change?

These screens represent the app’s current state, as you can see it’s pretty bare bones. It has the information users need, like glucose levels, stats, and the user’s insulin pump status. Nothing more, nothing less.

Home Screen

While the prominent glucose level display and trend indicator exist, the graph's four overlaid data sets create a confusing experience.

Time In Range Screen

Good, I can see stats to gauge the quality of my glucose within the last 24h, but users need more information to make calculated decisions.

Status & Settings Screen

It’s great that I can see how much insulin and battery I have left in my insulin pump, but there has to be a better way to display this information.

Persona & Journey Map

As I define the problem further, you can consider Jessie as the manifestation of my research, highlighting specific goals and pain points.

A persona profile for Jessie Roy, a 30-year-old Type 1 diabetic from Toronto, who is a male, single UX designer with a Bachelor's degree. Motivations include maintaining healthy glucose levels to avoid complications. Goals are real-time glucose monitoring, trend analysis, and insulin delivery. Pain points are a cluttered app interface and inconvenience in handling insulin pumps in social settings. Personality traits include being introverted, thinking, judging, and intuitive. Skills highlighted are in mobile apps, meal planning, and carb counting. Associated brands are MoMA, Medium, Vice, SJCB, and Medtronic.

Problem Statement

“How can the MiniMed app be transformed into an essential resource for Type 1 diabetics through significant improvements in functionality, accessibility, and design?”

Intended outcomes

  • Overhaul the UI with a new color scheme, fonts, and micro-interactions to make the app enjoyable to use

  • Show what new functionality could look like if users could deliver insulin directly from the app

  • Improve accessibility and the overall clarity of the app so users can access their data to find patterns and make informed decisions about their health quickly

How it COuld Look

I dabbled with Dribbble and perused Pinterest to pinpoint a suitable art style. My focus: healthcare interfaces that prioritize clear, accessible information. A grid-based layout, reminiscent of a bento box with its distinct line and shape divisions, stood out as a compelling organizational structure. Finally, a quick mind map solidified the screen and content requirements, transforming scattered ideas into a focused design plan.

Mid-Fidelity Screens

High-Fidelity

I’m going to try and bring this back full circle for a second, let’s think about the problem statement and pain points users expressed online to create a short story (@hiringmanager, please humour me for a sec) using Jessie as an example 👉

  • Jessie’s at a wedding wearing a button-up shirt tucked into his pants. A notification tells him his sugar is rising, and he needs to give himself insulin. He can’t take out his insulin pump because it’s tucked under his shirt, so he needs to go somewhere private to undo his pants and untuck his shirt to get to his pump. He opens the current MiniMed app to check how much insulin he needs based on his sugar and carb intake. Keep in mind it’s a wedding, he might be a little tipsy, and looking at the current graph, each stacked on top of each other, makes him dizzy. He’s no amateur though, but he ain’t happy. He takes a few minutes to see where his sugar is trending and gives himself the correct dose of insulin. FIN.

  • Jessie’s at a wedding (tipsy) and his pump is hard to get to without a “wardrobe change” while his sugar rises. He takes a step off the dance floor and whips out the MiniMed mobile app to scan only the specific chart he needs to understand how much insulin is required. He navigates to the bolus screen and boom, job done.

Now you might ask, “How was it so much easier the second time around?”. The answer is based on two main things:

User Flow: The new app uses a primary chart as well as a bento grid that users can swipe through quickly. This simplifies the graphs and makes it easy to decipher at a glance. This is especially important when users need information quickly, along with users who may have limited vision.

Functionality: I’m aware the app may not have this functionality currently due to regulatory reasons, however I wanted to design a bolus function the way I thought most users would find helpful. This means easy access, proactive recommendations, and a clear separation of information through the app’s structure and colour coding, making it a breeze to use digitally and physically.

Moving to mid-fidelity, I redesigned the existing charts, empowering users to grasp trends and make informed decisions by removing overly complicated elements that served no purpose. Additionally, I broke each chart into individual screens for quicker comprehension.

Most importantly, I integrated an insulin bolus function so users don’t have to leave the app. This includes a smart dose recommendation, factoring in current glucose and carbohydrate intake, alongside a custom entry option.

These decisions were made to remedy specific pain points, such as the need for easy access to information and the ability to bolus insulin directly from the app.
