STIM OnTrack App

Bone Growth Therapy devices stimulate the bone's healing process by sending electromagnetic pulses to the injury. The STIM OnTrack app pairs with Bone Growth Therapy's devices by helping patients adhere to their therapy device prescriptions and improve their clinical outcomes. My role was to redesign this app from the ground up.

The Problem

Doctors were frustrated because they could not sync more than one device to the app and could only have one therapy prescribed to patients at a time. This became an issue when doctors prescribed multiple therapies to a patient for treatment but there was only room for one treatment plan on the app. Also, the "PROM" button, a survey for patients, proved unpopular because it was confusing and only a few users tapped on it.

The Solution

I modernized the outdated UI and I addressed the doctors and patients frustrations by adding the ability to have multiple devices and therapies on a single account. Also, I replaced the ambiguous PROM button with My Therapy in the nav bar. 

Common pain points form 6 patients, ages 27-65

• Don’t know what PROM button in nav. is stands for
• Can’t pause the therapy after user starts
• Can’t control the EMP level
• Content under resources is vague

Common pain points from doctors ages, 48-59

• Can only add one STIM device at a time
• Can only prescribe one therapy plan at a time
• PROM seems irrelevant to recovery efforts

Feedback on the Old Design

Analytics Gathering

Results

Only 41 out of 254 users tapped on the PROM button and out of the 41 users 16 started the survey and only 5 competed and submitted it. After analyzing the data, it was clear that users were not interested in the PROM button and there was a low conversion rate.

User Flow Sample

This is a snippet of the user flow I created for first time users. After presenting this flow to my Product team I learned there are potential gaps when users attempt to connect their medical device to the mobile app.

I initially designed the flow (left image) assuming that every user has access to or is capable of using their phone camera to scan the bar code on the medical device. I failed to see that some users have disabilities or tech limitations that prohibits them to scan a picture of their device. This led to...

Alternative ways for users to input their serial number

• Take a photo
• Manually type it out
• Use voice to say it out loud
• I don't have one or I need more help

Ultimately, I learned to design more inclusively for all types of users.

Lo-Fi Wireframes

After identifying issues with the old app and creating a new user flow chart I mocked up these wireframes and presented them to my stakeholders for feedback. There were a few minor edits such as relocating the hamburger menu to the bottom nav.

Hi-Fi Screens

Overall, feedback was positive and the new UI was well received. My stakeholders liked the additional features that I added such as the multiple therapy options on the home screen.

Conclusion

Through user research we discovered significant pain-points for doctors and patients when using the STIM onTrack app. We gathered analytics and user interviews to make data-driven decisions throughout the UI/UX process to help solve for gaps and gain stakeholder buy-in.

The complete redesign of the STIM OnTrack app successfully addressed the frustrations faced by users. The modernized UI, support for multiple devices and therapies, and the replacement of the confusing PROM button led to an improved conversion rate and a positive impact on the business.
