Before you start

Is this a food intolerance test?

No. It's a self-tracking tool that shows patterns in your own log, so you and your doctor can decide what to test next. It doesn't diagnose anything.

Do I have to type every ingredient?

No. Type "chicken burrito with salsa" and it lists the likely ingredients for you to confirm. A barcode pulls the real list.

How long until I see suspects?

A first list after 7 days of logging. Most people see clearer patterns after 3–4 weeks.

Can I cancel?

Yes, any time from your account. You won't be charged if you cancel during the 7-day trial.

All questions, and where the data comes from

Test kits can't name your trigger. Your own log can.

Allergists say IgG kits can't name your trigger foods. What they point to: log what you eat and how you feel, then test one suspect with a short break and a reintroduction.

“Unfortunately, no single test exists that can give you this answer.”
