The problem
Built for real allergy workflows
Around 250 million people worldwide live with a food allergy. For some, a wrong ingredient can trigger anaphylaxis: a sudden, severe reaction that can close airways and needs epinephrine and emergency care within minutes. That turns daily life into scans, labels, profiles, and moments where seconds matter.
Capabilities
What you can do
Everyday tools for living with severe allergies, without turning safety into busywork.

From life to product
Making personal risk usable
I live with anaphylaxis myself. For years the tools around severe allergy felt outdated: paper cards, vague labels, and information that is hard to reach when it matters. I wanted something modern.
AllergyReady helps in those moments. Scan a barcode for Safe / Traces / Unsafe before you eat. Keep profiles with medications and contacts. Put an emergency QR on the Lock Screen so first responders can read your allergy info without unlocking the phone. Blood test values and a highest-values widget stay close when you need them under pressure.
