As answered by people managing DeveloperToolStack and Simple Allergy Alert.
Simple Allergy Alert's answer:
Instead of relying on multiple tools, it combines personalised allergy translation cards in more than 100 languages, an emergency medical card, and local emergency numbers for the country you’re visiting - all in one app.
Simple Allergy Alert's answer:
People with food allergies who travel, along with parents travelling with allergic children.
Simple Allergy Alert's answer:
Simple Allergy Alert covers every aspect of making servers aware of your allergic restrictions - simply. You can customise your alerts to your specific needs depending on what country you are in, or what kind of restaurant. Add and remove cards as and when you need them.
Simple Allergy Alert's answer:
I have a severe nut allergy myself. After a life threatening anaphylactic reaction while travelling, I got tired of printing allergy cards every time I visited a new country. I built Simple Allergy Alert so I could generate a card on the spot, in the local language, with an emergency card ready in case something went wrong. I use it myself on every trip.
Simple Allergy Alert's answer:
Vite, React, and TypeScript with shadcn/ui components, wrapped in Capacitor for the Android build. The backend runs on Nitro. Custom allergen translations use the Google Cloud Translation API. Payments run through Lemon Squeezy for the web app and Google Play billing for Android.
