Frequently Asked Questions
What is Allerwise?
Allerwise is a mobile app that helps you check whether a packaged product contains an allergen you avoid. Just scan the barcode and the app reads the ingredients for you.
How does Allerwise work?
You set up a profile with the allergens you avoid. Point your camera at a barcode. Allerwise pulls the ingredient list from Open Food Facts and matches it against your profile. You get one of three verdicts: safe (green), caution (yellow), or avoid (red).
What allergens does Allerwise detect?
Thirteen presets covering the most common food allergens: peanuts, tree nuts, milk, eggs, soy, wheat, gluten, sesame, shellfish, fish, sulphites, mustard, and celery.
Is Allerwise free?
Yes. The free tier covers daily scans and a single profile. The optional Pro upgrade unlocks unlimited scans, full scan history, favorites, multiple profiles, and an additives breakdown.
Is Allerwise available on the App Store and Google Play?
Yes — Allerwise is published on both the Apple App Store and Google Play.
Is Allerwise accurate?
Allerwise is only as accurate as the underlying Open Food Facts data, which is community-edited and may be incomplete or wrong. Always read the product packaging before you eat. Treat the app as a hint, not a final word.
Can I use Allerwise if my allergies are life-threatening?
Allerwise is an informational tool, not a medical device. If you have a severe allergy, do not rely on the app alone — read the packaging, follow your doctor's guidance, and carry your prescribed medication.
How do I cancel my subscription?
Subscriptions are billed by Apple or Google. Cancel any time from your store account: App Store → Settings → your name → Subscriptions, or Google Play → Account → Payments & Subscriptions. Cancellation takes effect at the end of the current period.
