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

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.

Just scanned

Two things stand out here: garlic is high-FODMAP and the cream adds lactose. A smaller portion usually sits easier.
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.
Thinking…Selected App Store reviews
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.
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
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.
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 gut. Belli remembers what got you here.
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.
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.
Based on your self-reported data. Not medical advice.
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.

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


And you keep going deeper

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

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

Mark a food as personally tolerated and Belli remembers that preference. It does not mean allergy-safe.
Ingredient context is informed by cited research and public sources. Ratings are directional, not clinical measurements.
Bellyweather learns from everyday meal and symptom check-ins. It is not medical or laboratory testing.
Your meals and symptoms stay yours. We never sell your data.
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
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.
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.
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.
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.
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.
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.
