Why AllerLink
Why AllerLink, not a crowd-sourced allergen app
Most allergen apps in this category work the same way: a crowd rating, or a single-condition filter applied to a whole menu. AllerLink works differently on purpose.
| Crowd-rated / single-filter apps | AllerLink | |
|---|---|---|
| Where the data comes from | Other diners' ratings, or a single generic allergen filter applied to the whole menu | That restaurant's own chef, reviewing every ingredient on every item |
| Level of detail | Usually one allergen flag per dish, or a dish tagged "contains nuts" with no further detail | Every ingredient flagged Contains or May Contain, for every allergen you've told it to watch for |
| Who's accountable | An anonymous rating — no single person stands behind it | A named chef, PIN-signed, with a timestamp — every declaration traces to a person |
| Checking for more than one allergen | Usually one allergen or condition at a time | A full profile — or several people's profiles at once — checked against every item together |
| What happens after the app | Often treated as the final word | Always ends with the waiter handoff — a deliberate safety step, not a fallback |
To be fair — a crowd-rated app can still be useful, especially where no chef-verified option exists yet. The comparison above describes how the two approaches typically work, not a claim about any specific competing product.
