Geuza had the hardware; load sensors, GPS, accelerometers but no interface. I designed the mobile app MVP in 3 weeks to translate sensor data into actionable safety feedback and demonstrate product viability to the Rwanda Ministry of Health

CHALLENGE
CHALLENGE
People using crutches face real risks falls, improper weight distribution, declining mobility but no assistive device gives them feedback. Geuza's smart crutch collected the data. The design problem was what to do with it. A data-heavy analytics app would be ignored by someone focused on walking safely. The interface had to surface only what prevents harmnot everything the sensors could measure

KEY DECISIONS
KEY DECISIONS
I choose alerts over dashboards. Real-time safety warnings are more useful to a rehabilitation patient than historical gait charts. Detailed analytics are available but secondary. Offline-first architecture was non-negotiable: users in recovery are often in environments without reliable connectivity. A safety-critical app that fails without internet is not a safety-critical app

SOLUTION
SOLUTION
Three core features: real-time alerts when weight distribution is unsafe, daily summaries of steps, balance, and fall risk, and offline-first sync that stores data locally and uploads when connected. Designed within the ESP32's technical constraints, no features that could not actually be built

IMPACT
IMPACT
The prototype was used directly in a Ministry of Health pitch, where the design demonstrated a credible safety monitoring use case for post-operative and rehabilitation patients. The 3-week timeline from no app to Ministry-ready prototype validated that the MVP scope decisions were correct, the three-state alert model was sufficient to convey clinical value without requiring clinical complexity
