A food & symptom diary · In development

Find your histamine triggers — one logged meal at a time.

A calibrated food-and-symptom diary that helps you spot the pattern — which aged cheese, leftover, or glass of wine set you off, hours later. We're building it. Join the waitlist for early access.

The histamine bucket

Stop guessing which food set you off.

Reactions can land hours after the meal, so the culprit hides in a blur of "was it the cheese, the wine, or the leftovers?" Same foods, two ways of looking at them:

Today — guessing

  • ??aged cheddar — headache 3h later?
  • ??spinach smoothie — hives, or coincidence?
  • ??leftover chicken — fine… or was it the wine?
  • ??notes-app scrawl, lost by next week

With HistaLog — calibrated

Aged cheddarLVL 9
Spinach smoothieLVL 6
Leftover chickenLVL 8

Every entry timestamped and placed on your personal scale — so the pattern shows itself.

FAQ

Straight answers

When does it launch?

We're building it now. The founding-member waitlist is how you find out first — we'll email you the moment early access opens, before any public launch.

What do I get for signing up?

First access to early builds, a locked-in founding-member price on HistaLog Plus, and a direct say in what we build first. We email rarely and only about HistaLog.

Is this medical advice?

No. HistaLog is a personal food-and-symptom diary that helps you see your own pattern. It does not diagnose, treat, or replace a clinician — bring what you log to your doctor or dietitian.

Where do the histamine levels come from?

They're curated from published food-histamine references. Levels vary with ripeness, storage, and preparation, so treat the scale as a calibrated starting point — your own log is what tunes it to you.

Can I export my data?

Yes. Export is part of the free diary — your log is yours. Take it to an appointment or keep your own copy whenever you like.
