A fresh look and a better fit. Allerio has a new app icon made for Liquid Glass, and the Settings and New card buttons now sit in the standard iOS toolbar. We also fixed the layout on iPhone Duo, so the welcome screen and My cards display properly whether it's folded or open.

This update is about reliability. We fixed a number of bugs and made things steadier under the hood, so your cards open, save and share the way you expect — including when the connection isn't at its best.

Making a card no longer waits on the network. The card opens right away and its QR code fills in as soon as it's ready — and when the connection is too weak to publish it, the card tells you and offers to try again instead of leaving you on a loading screen. You can now save a card to Photos even offline, and we let you know first when the saved image won't carry a scannable code. Your list of cards shows when each card was created and when you last presented it, and Settings tells you whether your cards are set to reach a new iPhone. Sharing offers a link only once that link really works. Settings also has a new privacy switch: you can turn off anonymous usage data whenever you like, and your allergens, notes and name are never sent. We also went over the wording in every language the app speaks.

Your cards are now safer and always with you. They back up to iCloud and sync across your devices, so they're there on a new iPhone — and they come back after a reinstall. You can now delete a card you no longer need, custom allergens get a fitting emoji automatically, and the wording for severe, life-threatening allergies is clearer so staff know to double-check. We also added four more card languages — Tagalog, Swahili, Tamil and Georgian — for 37 in all, and made sharing and the card details smoother throughout.

This update is all about the details. Your cards now live in a smooth, swipeable carousel, and any note you add to an allergen appears right on the card you show staff — in their language. Add the Allerio control to Control Center or the Action button to bring up a card in one tap. Plus crisper allergen icons and translation fixes across all 33 languages.
