How it works
No jargon, no setup — here's the whole idea in three steps.
1. Write down what you eat and how you feel
Each day, log your meals — type a food name, scan a barcode, snap a photo, or just write "chicken wrap and an iced latte" and let the app figure out the foods. When your gut acts up, log that too: a simple 0–5 for how bad it was. That's all the work there is.
It gets faster the longer you use it, too. The app notices your routine — the coffee you have every morning, the exact lunch you keep coming back to — and turns your usual foods and meals into one-tap buttons. Logging that same breakfast becomes a single tap, not a search.
And it works wherever you are: at a restaurant with no signal, on a plane, in a basement gym — log anyway. Entries are saved on your device and sync themselves the moment you're back online, with the original time intact. Meals happen everywhere; your log keeps up.
2. The app finds your patterns
IBS reactions are sneaky: they can show up anywhere from 4 to 48 hours after eating, which is why it's so hard to spot your triggers by memory. The app compares the hours before your bad days with the same hours on your good days, food by food. After about a week of logging, each food starts getting a verdict — safe, suspect, or trigger — with a confidence score that grows as you log more.
One thing we're careful about: foods you eat every day (rice, coffee, bread) show up before every symptom just by being everywhere. Simpler apps flag those as triggers by mistake. Ours accounts for that, so your daily staples aren't falsely accused.
3. Hand your dietitian the proof
One tap creates a PDF report: your likely triggers with confidence scores, your symptom trend, foods that came back clean, and any notes you want your dietitian or doctor to read. You choose exactly which personal details appear on it. Appointments go from "I think onions might bother me?" to a document you can work through together.
Ready for more? Reintroduction
If you're following the full low-FODMAP protocol with your dietitian, the app also guides phase 2: after a couple of weeks of logging, you can run structured 3-day "challenges" — testing one FODMAP group at a time with suggested foods and portions — and the results go on your report too. If you don't know what any of that means, ignore it: daily logging is all you need to start.
Common questions
How long until I see results? First verdicts usually appear within about a week. Two weeks of honest logging gives the clearest picture.
Do I need to log everything? The more complete your log, the better the analysis — but don't quit over a missed meal. Rough and consistent beats perfect and abandoned.
Is my data private? Yes. Your logs are visible only to you and are used only to compute your own analysis. Nothing goes on the PDF unless you tick it. See our Privacy Policy for the details.
Does it work without internet? Logging does — meals and symptoms save on your device and sync automatically when you're reconnected. Features that run on our servers (photo analysis, barcode lookup, AI insights, the PDF report) need a connection, and the app tells you which when you're offline.
What's a magic link? A way to sign in without a password: enter your email, we send you a link, clicking it signs you in. Just open it in the same browser you asked from.
That's everything. Create a free account and log your first meal — the checklist inside walks you through the rest.
