Finally know what your body can handle. Log meals, track reactions, and discover your personal
patterns. Built by someone who lives with histamine intolerance.
Living with histamine intolerance, lactose intolerance, or celiac disease means every
meal is a guessing game. CanIEat turns that guessing into patterns — so you finally
know what's safe for your body.
Built by someone who lives with histamine intolerance. No generic food diary. No
confusing charts. Just a simple, focused tool that learns alongside you.
LOG YOUR MEALS IN SECONDS
· Database of 500+ foods rated by histamine, lactose, and gluten content (based on
the SIGHI 2024 list)
· Quick 5-second daily check-in — how are you feeling today?
· Log individual meals with reaction type, symptoms, and notes
· Camera scan to identify foods from packaging
· Recently used foods for fast repeat logging
DISCOVER YOUR PATTERNS
· See which foods cause reactions most often
· Spot dangerous combinations — not just individual foods
· Track non-food triggers: stress, sleep, hormonal cycle, exercise
· Statistics and trend charts that actually make sense
· Heatmap calendar — see your good and bad days at a glance
ANCHOR FOODS SYSTEM
Set your daily staples once. Every check-in pre-fills them — you only note what was
different. Perfect for isolating the real culprits on bad days.
STREAK SYSTEM
Consistency is everything with intolerance tracking. The triple medal streak rewards
you for logging — not for being symptom-free. Because honest data beats perfect data.
YOUR DATA, YOUR DEVICE
· All data stored privately on your device. No cloud, no servers.
· No account required. No ads. No subscription. Pay once.
· Export your full history as PDF or JSON — perfect for sharing with your doctor
WHO IS CANIEAT FOR?
· Histamine intolerance — full SIGHI database with liberators and DAO blockers marked
· Lactose intolerance — all dairy products rated by lactose level
· Celiac disease — gluten levels for every food in the database
· Anyone managing multiple food intolerances at once
Managing your intolerance with pen and paper is exhausting.
CanIEat gives you the clarity you deserve.
