How it works

Scan it, score it, ask Belli anything.

01

Scan anything

A meal, a menu, a nutrition label, a barcode — point your phone and Belli reads every ingredient it can see in about six seconds.

Get your number

Each ingredient gets a directional green, yellow, or orange flag: green is lower, yellow is worth a look, orange is the one to watch. Add them up and the meal gets a 0–100 score.

Two things stand out here: garlic is high-FODMAP and the cream adds lactose. A smaller portion usually sits easier.

03

Ask Belli anything

Snap a restaurant menu, photograph a product label, or just ask. Belli is your food-and-logging assistant in plain English. For allergies, confirm ingredients with the restaurant or manufacturer.

Highly informative and user-friendly

I'm finding it so helpful when it comes to learning about what I'm eating and how it might affect me. I love being able to take a photo of a menu and get immediate suggestions about what to consider ordering.

Don't usually leave reviews but

It's the first food app I've used that's actually about understanding how what you eat affects your body — not just counting calories or hitting macro targets.

The payoff

You learn your own body, a little more every day.

Belli doesn't forget you overnight. Every meal you scan and every day you check in adds up, until the patterns stop feeling like a mystery.

Week 1

It starts with two taps a day

Scan your plate, then tell Belli how you felt. That's the whole job: the “what you ate” and the “how it went” that no food diary ever connects.

How's your gut?

Calm

Calm

PAINFULCALM

Calm gut. Belli remembers what got you here.

Week 2

Your own patterns surface

Belli compares each meal with your usual check-ins and shows the pattern with receipts: “bloating followed 6 of 10 meals with onions, about 3× your overall rate.” A lead to review, not proof of cause.

WarningJust noticed
OnionBloating
your overall · 20%
60%

Bloating in 6 of 10 meals with onion. Your rate with onion is about 3× your overall rate.

Try skipping onion for a few days, then reintroduce to confirm.

Investigate pattern

Based on your self-reported data. Not medical advice.

Week 6

Your whole day, understood

Each evening Belli sums up your day in plain English and compares your gut, energy, and symptom-free meal check-ins with your own rolling average, so you can see how days differ over time.

Today's meals

A steady day overall. Lunch settled well; dinner ran a little rougher with a few flagged ingredients.

And you keep going deeper

Your food bible

2,600 ingredient profiles with directional context to review before you order.

Fifteen gut dimensions

FODMAP, histamine, glycemic load, and twelve more. Read on every bite.

Your calls, remembered

Mark a food as personally tolerated and Belli remembers that preference. It does not mean allergy-safe.

Grounded in the research

Ingredient context is informed by cited research and public sources. Ratings are directional, not clinical measurements.

No test kit required

Bellyweather learns from everyday meal and symptom check-ins. It is not medical or laboratory testing.

Private by default

Your meals and symptoms stay yours. We never sell your data.

See how food lines up with how you feel.

With enough check-ins, a hunch can become a pattern you can inspect — your meals, your rough days, and the receipts behind both. Patterns are associations, not diagnoses. Free for 7 days, then $59.99/year.

Questions

What people ask before they scan

How much does it cost?

Free for 7 days, then $59.99/year. You get the full app during the trial — scanning, scoring, and your pattern check-ins — so you can see whether the read matches your own gut before you pay for the year.

Isn't this just a food diary?

A diary remembers what you ate. Belli helps summarize the pattern in it — which foods appeared more often before a bad day. You scan and check in, and over time it lines up meals with your self-reported rough days. Those associations are leads to review, not proof that a food drove a flare.

How is this different from a basic food scanner?

A basic scanner can summarize a product's ingredients. Bellyweather also lets you compare that context with your own meal and symptom check-ins over time. It surfaces repeated associations for you to inspect; it does not determine that an ingredient caused a symptom.

How long until it can show a useful pattern?

The scan score is instant. Food-and-check-in associations take repeated observations — about two weeks is a useful starting point, but results vary with how often you log. Bellyweather never treats an association as a confirmed trigger or diagnosis.

Is Bellyweather a medical device?

No. It's a tracking and pattern-spotting tool, not a diagnosis and not medical advice. It can help you notice what may be linked to your symptoms and bring better notes to a doctor or dietitian — but it doesn't replace one.

Which conditions is this for?

It may be useful for people logging meals alongside bloating, reflux, or other symptoms, including people already working with a clinician on IBS, histamine sensitivity, GERD, or gout. Bellyweather does not diagnose, monitor, or treat those conditions.
