Hey, I'm Ola, I built BellyMystery.

My son has a food intolerance. When we sat down with a dietitian, the advice was to log what he ate and how he reacted, and she handed us a paper notepad to do it with. It lasted about four days. We'd forget an ingredient, forget a day, and by the time a symptom showed up we'd already lost track of what he'd eaten two days before.

So I built the thing I wished we'd had. Logging has to be fast, a symptom entry takes under 15 seconds, a meal photo and description/ingredients under 30, because if it's slow you stop doing it, especially at the end of a long day with a kid. Once there's enough logged, it looks across the entries for which foods keep showing up before a reaction and shows you that with a confidence score, not a verdict.

It doesn't diagnose anything. Only a dietician or a doctor can do that. What it gives you is something concrete to bring to the next appointment instead of trying to remember what happened or write it down on a notepad.

Your diary stays on your phone. The only things that leave the device are a meal photo, so it can pull out ingredients, and a stats summary, so it can write up the pattern in plain language.

Let me know if you've got questions, especially if you've ever been handed a paper notepad and told to "just track it."
