Juva Health Redesign
Juva treats migraine through biofeedback therapy. Using their iPhone camera, patients run guided sessions in the app, track symptoms, and build a practice over time, on their own or alongside a doctor.
Role :
Senior Product Designer
Industry :
Telehealth / Therapy
Project Duration :
1 Year
Year :
2021
Problem :
The product was coming out of prototype and research, and a full design pass was next.
We started building light and dark together, on the prevailing assumption that a well-designed app shipped both. Screenshot comparisons across multiple versions of each said otherwise. Dark was heavily favored, and patients were direct about why: they would never look at a bright screen while managing a migraine. Light sensitivity is a symptom of the condition the product treats, which made light mode not just unhelpful but potentially harmful during the exact session it was built to support.
I pushed to make dark-only a primary goal of the redesign. It was the right call clinically, and it removed the cost of maintaining two schemes.
Solution :
Dark was treated as a clinical requirement, not a display preference. Contrast, type, and illustration were tuned to stay legible without becoming a source of strain.
The session lifecycle became the spine of the app: pre-session survey, calibration, session, results. Sequenced so a patient in discomfort makes the fewest possible decisions.
Around it sat the rest of the program. Guided learning, biofeedback games, nightly check-ins, activity log, reminders. One component language across all of it.
Challenge :
Camera capture was primary, but not always available. Device conditions and moment-to-moment failures meant the session needed a second path through a finger sensor. Rather than fail, the interface carries a version for each condition. That doubled the session screens and had to be specified case by case.
Survey burden was the harder call. The pre and post session survey was explored from three questions up to eight, weighing what clinicians wanted to capture against what a patient in pain will actually finish. The check-in flow went through six versions on the same tension.
Summary :
The redesign shipped dark-only, ending the two-scheme question for the product. The session lifecycle held as the spine of the app, with the learning program, games, check-ins, and logging built on the same component language. The Juva Design Kit became the source those screens were assembled from rather than a library maintained alongside them.
