Because MyHistamate is not a doctor, it doesn't diagnose and it can't promise that a food is safe for you.
It's a tool that helps you organise your information, notice what keeps coming back and have more context when you make decisions or when you talk to your doctor.
It doesn't tell you whether you have histamine intolerance
MyHistamate doesn't diagnose and it doesn't confirm a diagnosis you've already been given.
Symptoms such as headaches, itching, tiredness or digestive problems can appear for many reasons, not only because of histamine. That's why the app doesn't try to decide what condition you have.
What it can do is help you come to your doctor with clearer information.
There's a big difference between “I itch a lot” and “over the past month I noted itching on 14 days, mostly in the evening and in certain contexts”.
I wrote more about this in the article on how to prepare for the conversation with your doctor.
It doesn't tell you that a food is 100% safe
The app has a basic classification of foods, starting from the SIGHI list, and on top of that come the tolerances you've observed yourself.
But that doesn't turn a suggestion into a guarantee.
In HIT, context matters a lot: how fresh the food is, how it was stored, what else you've eaten that day and how you feel in that period.
That's why I prefer MyHistamate to say “this looks like a better fit for your profile” rather than “you can eat this without any problems”.
And that's also why the app has a personal tolerance map. The general list is the starting point. Your experience is what personalises it.
I've also explained separately the difference between foods that contain histamine and those considered histamine liberators.
It doesn't know what happens in a restaurant kitchen
The menu scan analyses what the menu says. If it says “grilled chicken breast”, the app has no way of knowing whether the chicken was marinated that morning, whether the sauce contains ingredients that don't appear in the description, or how fresh the dish is.
That's why the restaurant suggestions also come with questions you can ask the waiter.
The scan doesn't replace the questions. It only helps you get faster to the dishes worth checking.
The AI doesn't receive your identity
For the features that use artificial intelligence — such as the assistant, the menu analysis or the summaries — only the information needed for that particular answer is sent.
That might be, for example, relevant information from your profile, fragments from your journal, or the photo of the menu you chose to analyse.
Your name, email address, password and login details are not sent to the AI model.
The details about how data is used and protected are explained separately in the app's privacy policy.
It can't find patterns if it has no data
MyHistamate can compare days, generate summaries and take your history into account.
If the journal is empty, the answers will inevitably be more general. The more days you note, the more context the app has to show you what keeps repeating.
That's also why I tried to make the journal very simple: because the information becomes more useful when it builds up over time.
It doesn't start charging you automatically after the trial
The trial lasts 7 days and doesn't ask for a card.
That means that at the end of the 7 days no payment appears automatically and you don't have to remember to cancel anything.
If you want to carry on with the AI features, that's when you choose a subscription.
If not, nothing happens automatically. Only the AI features stop — the assistant, the menu scan and the summaries. The journal, the foods and everything you've noted until then stay yours and you can keep using them.
I wanted it to be simple here too: you try the app and then you decide whether it's useful enough for you to continue.
So what does MyHistamate do?
In essence, it does something much simpler than it seems.
It puts together your meals, your symptoms, your cycle, your sleep and the other things you note. It shows you what seems to repeat. It helps you keep track of reintroductions. It cuts a restaurant menu down to a few options worth checking.
And when you get to the doctor, you no longer have to reconstruct the last three months from memory.
That is MyHistamate's ambition.
Not to decide for you.
But to help you see more clearly the information about yourself that is otherwise very easy to lose.
MyHistamate is on the App Store and Google Play
The app has come out of testing and can be installed from the App Store and Google Play.
The first seven days are free and complete, with no card.
MyHistamate doesn't promise certainties. It tries to give you context.
