Histamine Intolerance & MCAS
Only for iPhone

Histamine builds up. A meal that was fine at breakfast can trigger you at dinner. Track your daily bucket, catch aging leftovers, and find your personal threshold.
Aged cheese. Leftovers. Red wine. If your symptoms feel random — headaches, flushing, hives, bloating, brain fog — they might not be.
Histamine intolerance is dose-dependent and cumulative. One moderate food is fine; the same food fourth in a day tips you over. That's why food lists with three colors keep failing you: the question is never "is this food safe?" — it's "does it fit into MY day?"
Low Histamine answers exactly that.
YOUR DAILY HISTAMINE BUCKET
Every meal fills your bucket. See how full you are right now, as a percent of your personal threshold — and how much still fits today. Home screen and lock screen widgets included.
SCAN ANY MEAL
Photo of your plate, barcode, or ingredients label. AI only recognizes the food — the verdict always comes from the SIGHI reference table. Composite dishes are computed from their ingredients: the worst one sets the verdict.
A VERDICT IN CONTEXT, NOT A COLOR
"Good to go — takes you to 66%" instead of a guessing game. Every verdict shows all three mechanisms — histamine level, liberators, DAO blockers — with an explanation, a source, and an honest confidence level. Where the literature disagrees (eggs, avocado, spinach), we say "sources differ" instead of pretending.
LEFTOVERS AGE — WE COUNT IT
Histamine builds up in stored food. Yesterday's dinner is not the same food today. Your fridge shelf tracks every dish's age, and we warn you before leftovers turn high.
FIND WHAT ACTUALLY GOT YOU
Reactions are delayed. Log one, and we analyze the last 24 hours — not just your last meal — ranking suspects across all three mechanisms plus freshness.
YOUR PERSONAL THRESHOLD
After two weeks of logging, we derive your threshold from your days with and without reactions. Everyone's limit is different — yours shouldn't come from a generic list.
YOUR BODY BEATS OUR DATA
Tap "I reacted" or "Fine for me" on any food — your flag overrides the reference data in every future verdict. Spotted an error? Report it from any card; fixes ship to everyone.
1,200+ FOODS, SIGHI-ANCHORED
