Solution
Go/No-go is a therapeutic game that helps patients learn to withhold responses on No/go trials. Patients are asked to interact with positive and neutral words while avoiding words associated with their condition.
Onboarding
Onboarding is crucial for treatment, as it educates first-time users on the benefits and effective use of the product.
Practice round
Even after onboarding, some participants faced challenges with the activity.
Confusion arose over task execution. Testing feedback indicated a need for clearer instructions or more support.
Working memory words
“Working Memory Words” is an additional activity in the Go/No-Go. activity. Patients are asked to remember and recall a list of specific words. This activity helps improve working memory.
Score
Participants want to track their performance. The Training Score at the end of the activity displays statistics on each patient’s progress.

How does it help the patient
Autonomy - This activity helps patients feel accomplished
Working Memory - Improving memory
Impulse Control - helps practice the ability to not react to triggers
Engagement - Both a distraction tool and game like experience
Cravings Management - reduces automatic responses to triggers and serves as a distraction tool

How it started - discovery and research
The user research phase lasted 9 months
Conducted 50+ patient and peer advisor interviews. I served as research moderator and note-taker.
“I’m interested in the finer details of the science behind these exercises. Whether these are conducted in clinical studies or what.”
- Research participant
Early design explorations
Initial ideas stem from the feedback from the science team and user interviews.
Wireframes onboarding - user testing
These designs were created during the exploration phase and helped gather valuable user research insights.
Iterations
Updates came from user feedback. The first version was too long and text-heavy, making onboarding tiring.
User testing
User testing revealed a desire for more performance and progress details. We added extra score information and exploration options.
Design system
Design system components annotation, and dev handoff
User journeys
Next steps - future concepts
Early explorations for the next steps. In order to make the game more engaging, we wanted to introduce different themes and animations.
Results and outcomes
High task completion and strong engagement were observed across multiple moderated usability sessions.
80%
Participants reported being very interested in brain training
70%
Participants said they would use the app daily
User Outcomes
Participants reported feeling more in control, encouraged by the idea that brain function can improve over time.
Testing revealed notable improvements in task accuracy and response speed across repeated sessions
Business Outcomes
Insights from early testing helped secure client buy-in and Phase 2 funding
