Trained on a curated corpus of public-domain emergency response material, including U.S. Department of Defense, NIH, and U.S. Army field manuals.
Burns, cuts, severe bleeding, sprains, strains, fractures, shock, head injuries.
Choking, CPR, cardiac arrest, anaphylaxis, severe allergic reactions.
Hypothermia, heat illness, frostbite, dehydration, altitude sickness.
Snake bites, insect stings, marine animal injuries, infection risk.
Water purification, signaling, shelter, basic navigation, fire-starting.
Common emergency triage decisions and escalation criteria. When to call 911, when to monitor, when to evacuate.
One download. Then your phone has a calm, action-first survival reference even when nothing else does.
Download from the App Store. On first launch the app downloads about 2.4 GB of AI model and reference content. Wi-Fi recommended. After that, you’re done.
Type a question. Get a direct, action-first answer in a few seconds. No signup, no network, no waiting.
The AI runs entirely on your device. Perfect for backcountry, off-grid travel, or any time signal is gone.
Other apps promise privacy. First Resort is incapable of leaking your data because the architecture makes it impossible.
The 4B-parameter model is downloaded to your device on first launch. No server roundtrip for any query.
No login. No email. No phone number. You install and use.
No telemetry, no crash beacons to third parties, no usage tracking.
After the one-time model download, the app makes no outbound network requests. Airplane mode works.
First Resort is a reference, not a doctor.
It is not a substitute for calling 911, going to an emergency room, or consulting a trained medical professional. In a real emergency, call help first if you can reach it. Use First Resort when you cannot reach professional care, or as a backup reference alongside it.
The model declines questions outside its scope (specific medication doses, legal advice, procedures requiring hands-on medical training) and points you to the appropriate resource. It is not a diagnosis tool.
Yes. After a one-time download on first launch (the AI model and reference content, about 2.4 GB), no internet connection is needed for any query. You can use it in airplane mode, on a plane, in the backcountry, or during a power outage.
The app binary itself is small (about 24 MB). On first launch, the app downloads about 2.4 GB of AI model and reference content from our public Hugging Face distribution. The download is gated behind a clear consent prompt, and we recommend Wi-Fi for it. Once downloaded, the app works fully offline with no further network use.
iPhone and iPad on iOS 17 or later. The AI model is optimized for Apple Silicon. Newer devices give faster responses; older devices may run more slowly but should still work.
The model is trained on a curated corpus of public-domain emergency response material, including U.S. Department of Defense, NIH, and U.S. Army field manuals, supplemented by standard first-aid reference content. Every release is tested against a 33-question rubric covering core accuracy, decline behavior on out-of-scope questions, and hallucination resistance.
No. After the initial model download, the app does not make outbound network calls during normal use. Your questions, your location, your typing history, all of it stays on your device. There is no account, no telemetry, and no analytics. The full privacy policy is at /first-resort-privacy-policy/.
No. First Resort is a reference, not a replacement for emergency services. In any real emergency, call 911 first if you can reach it. Use the app when you cannot reach professional care, or as a backup reference while you wait.
No signup. No subscription. No internet required after setup. Install once and have a calm, direct survival reference any time you need it.
