Built for the moment it matters
Every screen designed for one-handed use under stress — large targets, high contrast, zero clutter.
Tap a symptom. Steady guides you from there.
See it in action
A 60-second walkthrough — from symptom tap to action plan.
The right response — matched to the reaction
Steady never shows you a wall of medical text. It gives you the three sentences you actually need.
Itchy skin, a few hives, sneezing, or mild stomach ache. Steady walks you through antihistamine dosing and what to watch for.
Spreading hives, mild wheeze, or repeated nausea. Treat now and Steady tells you exactly what escalation looks like.
Throat or tongue swelling, breathing trouble, faintness. Epinephrine instructions and a 911 call-prompt appear immediately.
Everything your allergy action plan needs — in one place
Designed with allergists’ protocols. Engineered for one-thumb use in a crisis.
Tap a symptom. Get a plan.
Select what you're feeling — skin, breathing, gut, or throat — and Steady instantly builds a step-by-step action plan matched to your severity.
Your rescue meds, front-and-center.
Store your epinephrine auto-injector, antihistamines, doses, and locations. In a crisis, they're one tap away — not buried in a settings menu.
Reaction history you actually own.
Every episode is logged with trigger, severity, and action. Share the timeline with your allergist instead of trying to remember dates.
Emergency contacts in one tap.
Severe reaction? Steady puts a direct-call button to your primary contact alongside the 911 prompt — so family is notified as fast as first responders.
Calibrated guidance — not generic advice.
Mild hives get calm home-care steps. Severe anaphylaxis gets epinephrine + 911 front-and-center. Red in Steady always means act now.
