iOS app design • www.qbtech.com
Qbtech is the market-leading provider of objective ADHD tests for patients 6-60 years old. The tests are FDA-approved and CE-marked. For more than 20 years, Qbtech has provided objective tests for in-clinic use only by healthcare professionals (B2B). For the first time in the company's history, our design efforts are bringing these tests to people at home. We designed a native iOS application that includes their objective ADHD assessment designed by clinical psychologists as well as resources, a symptoms tracker, and collaborating clinics. The application is geared towards adults and parents.
Duration: 10 months
My role: Product designer
Team 1: 1 designer, 1 product manager, 2 iOS developers, 1 back-end developer, 1 product owner, 1 test and verification engineer
Team 2: 2 iOS developers, 1 test and verification engineer
Tasks included: Research, wireframes, prototyping, stakeholder management, roadmap shaping, high fidelity designs, design system, documentation
For the last 22 years of its lifetime, the company has been providing hardware (i.e. headband, motion-tracking camera, and laptop) to clinicians around the world to perform ADHD tests. The company had a few future goals:
When I joined the company, the project was in the discovery phase. I became part of a small design team alongside a lead designer and a junior designer. At that point, the lead designer had initiated research, conducting usability testing with 15 participants from the U.S. using an early prototype. I quickly got involved in the process.
After the research was completed, I worked closely with the lead designer to analyze the insights and shape the product direction. From there, I partnered with the product manager to define the product roadmap and led the design efforts for the app. Together, we identified and prioritized four key features to build the app from the ground up.
To focus on the functionality and involve the team as soon as possible, I started with wireframes and low-fidelity prototypes. This approach helped us focus more on the flow and content instead of the visual aspects of the app.
According to medical experts, ADHD is hereditary. Based on that fact, it was decided that the app should give to individuals a more personalised experience. From the start, in the app's onboarding, the user can choose to create multiple profiles (for themselves, their child or both). The finalised version of the app included four main features:
One of the app's key features was offering the user a symptoms and mood tracker. By tracking their symptoms and mood daily, the user would create a journal that would help them recognise triggers and patterns of behavior associated with ADHD. They would also have the opportunity to share their journal with their doctor to aid with their diagnosis and treatment.
To ensure consistency across the application and establish a common language between us and the developers, our design lead and I created the app's design system from the ground up. I was responsible for maintaining it and introducing new components. Learning variables helped us set up the app's light and dark modes efficiently. We referenced the HIG (Human Interface Guidelines) at every step of the way, as we designed for iOS.
As part of the standard operational procedure dictated by the principles and methods of HFE (Human Factors Engineering) and user-centered design, I invited five users to validate the application's design. I was acting as the moderator. The five participants were assigned tasks guiding them to complete all the main flows in the app while sharing their comments and experiences with me. I documented and compiled their input in a formal validation report as directed by the relevant company's SOP document.
Designing and building the app concluded in 10 months and it was launched in Ireland. The purpose is to initially test it in Ireland as it is a smaller English-speaking target group. This will give us the opportunity to collect as much feedback as possible and continue with data-driven iterations. In 6 months time, we are planning to launch the new and improved app in the US market.
