A card you hand to a waiter, or show to a paramedic. It states what you are allergic to in the language of the place you are standing in, with the local emergency number printed on it.

Two cards, two situations

One for a kitchen, one for an emergency. Tap and it fills the screen at full brightness, which is what you want when you are handing a phone to someone across a counter.

It finds what you mean

Search by any name in any language: “Advil” finds ibuprofen, “iodine” finds contrast agents. Severity comes first in the list, because that is what matters when someone is reading fast.

It tells you what it is not sure of

The card translations have not been reviewed by native speakers, and the app says so. An allergen with no translation in the card’s language shows in English, marked as untranslated, instead of quietly becoming a word that means something else.

Your auto-injector, before it expires

Reminders at sixty days, thirty, seven, and on the day. An expired auto-injector is a problem you only discover at the worst moment.

Profiles for the family

One profile per person, with the active one ticked. The card follows whoever you switch to.

Health, both ways — carefully

Cautela can read the allergies in your clinical records, and write the symptoms of a reaction you log. What comes from Health stays on the device and never goes to iCloud. The privacy page is explicit about it.

Seven languages, nine variants: English, French, German, Spanish (Spain and Latin America), Italian, Japanese and Portuguese (Brazil and Portugal). The cards themselves go further, to thirty-four.

Cautela is at version 0.1. There is nothing to download yet — this page will carry the link when there is.
