Technology that saves lives..
Built an offline-first emergency app based on WHO/Red Cross guidelines — looking for feedback from people with field experience
Over the past months I've been developing SelfAid, a free app meant to help in situations where every second counts and there's no network coverage.
The core idea: most first-aid apps assume you have signal. This one is built to work fully offline, using on-device AI to walk someone through emergency steps — designed to be usable by children, tourists facing a language barrier, or someone in shock who can barely think straight.
A few design choices I'd love feedback on from people who've actually worked in humanitarian or emergency contexts:
- Offline-first, "Mountain Mode": works with zero connectivity, sends distress signals when possible, meant for remote areas — mountains, deserts, disaster zones.
- Content sourced from WHO and Red Cross protocols, not generic advice.
- No data collection, no ads, open-source — the guiding principle was "saving lives, not collecting data."
I'm not looking to sell anything here — genuinely trying to figure out if this solves a real problem or if I'm missing something obvious that people with field experience would catch immediately. Has anyone here worked with offline emergency tools before? What actually breaks down in the field that an app like this should account for?
(Happy to share more technical details or the project link in comments if anyone's interested — didn't want to lead with that here.)
