Why “Best” Depends on Your Goal
If you only want a rough feel for how “clean” a product looks, many apps can show a score. If you have patch-tested allergens or a history of contact dermatitis, the best tool is the one that:
- Parses real INCI from labels or catalog entries.
- Compares them to your saved allergens and cross-reactors.
- Explains why something is flagged, in patient-friendly language.
That is a different problem from ranking ingredients for the average consumer.
What to Look For
| Capability | Why it matters |
|---|---|
| Personal allergen profile | Without it, “safe” is meaningless for contact allergy. |
| INCI-level matching | Cosmetic labels use INCI; fuzzy common names are not enough alone. |
| Patch test awareness | Your clinician’s panel should map to how the app warns you. |
| Clinical allergen sources | ACDS/CARD-style grounding reduces folklore and fear-mongering. |
| Transparency | Clear disclaimers: educational, not a medical device. |

AllerNote is built around your allergen profile: add allergens, optionally import patch test text or photos, and run scans or browse the product catalog with personalized Safe / Warning / Avoid outcomes.
