Cautela: your allergies, said clearly, in the language of wherever you are
Studio Nidello launches an App Store app that turns a list of allergies into cards ready to show at a restaurant or to emergency services, in 34 languages and with no network needed.
Canada, October 27, 2026. Studio Nidello today announced Cautela for iPhone and iPad. People enter their allergies once, with their real severity; the app turns them into a kitchen card, an emergency card and a PDF for the doctor, in the language of the destination country.
The problem
At a restaurant, abroad or in an emergency, a person with allergies has to explain quickly and without mistakes what they cannot eat or be given. Often it isn't in their language, and sometimes they can no longer speak.
What Cautela does
- A kitchen card to show the server or chef: the food, its severity, and whether traces or the cooked food are tolerated.
- An emergency card with what to do and the local emergency number (119 in Japan, 112 in Europe, 911 in North America).
- 34 card languages: pick a destination and the card switches language. Tap it for full screen at full brightness.
- Works offline: cards, translations and emergency numbers are all in the app.
- More than 370 allergens: foods (including the priority allergens of Canada, the European Union, the United States and Japan), medications, venoms, latex, pollens and animals. Search works by brand too: "Advil" finds ibuprofen.
- Treatments and reminders: auto-injectors and other treatments, with reminders before they expire.
- Reaction journal, with symptoms that can be saved to the Health app.
- The whole family: one profile per person, shareable with a partner.
Your data stays yours
No account, no Cautela server, no tracking. Data stays on the device or in the user's own iCloud. Cautela records what the person and their doctor have established: it makes no diagnosis and never calculates a dose.

Availability
Cautela is available now on the App Store for iPhone and iPad for CA$4.99 in Canada (local pricing elsewhere), with no subscription and no in-app purchases. The interface is available in 13 languages.
