Questions

Good to know.

The essentials before you download.

Is ER really free?
Yes — ER is free to download and use. An optional Premium unlocks everything for $2.99/month or $24.99/year, and helps us keep building.
Does it replace calling 911?
No — and it never will. ER guides you through the critical minutes before help arrives. In any real emergency, call 911 first, then let ER walk you step by step.
Do you collect my data?
No. No accounts, no tracking, no selling your information. ER works for you — and no one else.
What emergencies does it cover?
Heart attack, CPR, anaphylaxis, seizure, opiate overdose, head injury, and burns — plus a First Aid library that includes choking and severe bleeding. Each is a clear, AI-guided protocol with short videos (and hands-free voice guidance coming soon).
Who is ER built for?
Anyone who wants to be ready to help in an emergency — parents, caregivers, teachers, coworkers, and anyone who might be there when someone needs help.
Is it on Android?
Yes — ER is on both iPhone and Android. Grab it on the App Store or Google Play, whichever you carry.
