Made by someone with histamine intolerance, for people who get it

Histeva grew out of my own need to make histamine intolerance easier to keep track of and a little less consuming day to day.

I wanted meals, symptoms and everything else I track in one place — simply, without more spreadsheets and scattered notes.

That is why I created Histeva — a diary I use myself, built for people who do not want histamine intolerance taking up headspace all day.

WHY KEEP TRACK

Without a record, the details fade.

After a few days, it can be hard to remember exactly what you ate, when a symptom appeared or what was happening that day. Your entries build a personal history you can return to anytime.

You do not have to piece together what happened days later.
Meals, symptoms, stress and activity are clearly shown side by side over time.
You have a concrete record to refer to when speaking with a healthcare professional.
Your history can help you notice what tends to recur in your entries.
