Discover Hlomo’s one-tap SOS app for South Africa—offline-ready alerts to neighbours and responders, custom Emergency Circles, and clear feedback when it matters most.

Hlomo Case Study
Overview
Hlomo began as a concept to reimagine emergency response across South Africa by tapping into trusted community networks. Over seven months at Sammi Studio, I wore many hats—co-founder, strategist, UX/UI designer and front-end developer—to sketch out an app where a single tap could alert neighbours and professional services alike, all within a calm, intuitive interface.
Challenge
We faced three core hurdles:
Complexity of existing systems: The 10111 call centre is hard to navigate, especially in high-stress moments.
Digital divide: Vulnerable groups (elders, refugees, people with disabilities) often struggle with jargon or network gaps.
Trust & adoption: Users needed confidence that their SOS signal would actually reach real help—fast.
Approach
Rather than build a half-baked prototype, we distilled our concept from:
Secondary research (public safety reports, mobile-money studies, global community-alert pilots)
Empathy mapping to define user states in crisis (anxiety, urgency, need for clarity)
From there, I designed in Figma:
A bold, single-tap SOS button that works offline and confirms once the alert is sent
An “Emergency Circle” setup where you pre-select trusted contacts and organisations
Dual notifications (neighbours + responders) with clear icons and colour cues
Cash & cashless options so anyone can respond, regardless of payment method
Takeaway & Reflections
Sketching Hlomo—without ever testing on real users—taught me how crucial every detail is when panic strikes. Some key lessons:
Simplicity wins: Fewer taps and clear feedback beats fancy features.
Design for failure: Offline fallbacks and retry cues are non-negotiable.
Empathy first: A calming palette and concise language can steady hearts in a crisis.
Even as a paper concept, Hlomo reinforced that life-saving innovation starts by deeply understanding community needs—and removing every barrier between a user in distress and the help they need.
