A free food diary app for allergies that finds your triggers

Allergy Hunter is a free online food and symptom diary for adults who want to find out what’s causing their reactions. Log what you eat, drink, take and are around, record symptoms like hives, rashes, an itchy mouth, headaches or stomach trouble, and IntelliTrak® compares what came before each reaction with your usual days to flag likely triggers. It works in any phone or computer browser, with nothing to install.

Over time you can see how the foods, drinks and medicines you log affect your symptoms and sleep, so you know what to keep and what to cut back on.

Platform: Supports iOS and Android (NO INSTALL REQUIRED).

Free, with no credit card. Allergy Hunter doesn’t diagnose allergies; it gives you a clear record and pattern report to review with your doctor or allergist.
