IBS & FODMAP food and symptom tracker
A clearer view of how food feels.
Track meals, symptoms, and patterns in one calm place, so your next decision is based on context.
As you scroll, a magnifying glass moves over a chicken and avocado bowl while GutLens surfaces an estimated meal calorie count, a macro breakdown, a FODMAP screening result noting sorbitol as a common IBS trigger, and a reviewable pattern linking avocado to recent bloating entries.
How GutLens turns meals into patterns.
GutLens brings food, symptoms, and context together without turning your day into a spreadsheet.
- Log
Capture meals and symptoms in the way that fits the moment.
- Notice
See the timing, ingredients, and signals that are easy to miss.
- Review
Keep estimated results visible, explainable, and open to review.
- Adjust
Use better context for your next choice, without diagnosis claims.
Meal and symptom tracking, built for IBS.
Three habits make the difference between logging data and understanding it.
Log without friction
Log by typing, scanning, searching, or reviewing a photo. GutLens reads packaging and estimates entries, so logging can fit the moment.
Connect meals and symptoms
Link symptoms to meals directly or review estimated timing windows. Each connection is labeled, and symptoms can be logged separately or linked later.
See the evidence, not just a verdict
Review exposure rates against your baseline with confidence tiers. Patterns need repeated exposures; one unusual day is not enough.
Food logging, photo review, trends, and Coach.
Every screen is backed by a real pipeline, not a black box.
Meal logging
Enter meals by text, barcode, product search, or photo; entries remain reviewable and editable.
- Natural language entry parses descriptions like "ate two eggs and toast" into a meal.
- Barcode and product search use USDA and Open Food Facts data.
- Ambiguous matches are flagged for review before they are logged.
- Totals update immediately and remain editable for corrections.
- Daily dashboard summarizes calories and macros at a glance.
Photo review
Photos estimate portions. Nutrition uses verified per-gram data after you confirm the portion.
Trends and patterns
Review daily nutrition totals. Trigger-food rankings need repeated occurrences and a meaningful severity signal.
Coach
Coach searches food and nutrition sources, checks FODMAP and safety status, and confirms portions before logging.
Honest about evidence, careful with your data.
Useful signals need clear limits and honest uncertainty.
Evidence and trust
Grounded in real food data
Nutrition comes from USDA, Open Food Facts, similar sources, or deterministic per-gram calculations, never language-model inventions.
Reviewable, not automatic
Photo and text matches auto-accept only above a high-confidence threshold; other matches await your review.
Uncertainty is disclosed, not hidden
Labels such as "Estimated match" and "Portion assumed" appear beside the numbers.
Not a diagnosis
Patterns are associations with confidence limits, not proof of causation. GutLens does not replace professional care.
Privacy
No ads, no behavioral tracking
GutLens does not collect location, device or ad identifiers, or behavioral analytics; it does not sell or profile your data.
Food lookups stay anonymous
Food searches share only query text or barcode with providers, never your identity or health data.
Your data, your control

Questions about GutLens, IBS, and FODMAPs.
Does GutLens diagnose anything?
No. GutLens shows patterns and estimates so you have more context for a conversation with a healthcare provider or dietitian. It doesn't diagnose IBS, food intolerance, or any other condition.
How does FODMAP screening work?
GutLens screens ingredient names, additive tags, and known FODMAP-relevant compounds like sorbitol. It's an ingredient-level screen, not a lab-verified serving-size classification, and low-confidence results are labeled "Not enough information" instead of guessed.
What counts as a "pattern"?
GutLens compares how often a symptom follows a food to your own baseline rate on days without that food. A pattern needs a meaningful run of exposures and a real gap above baseline before it shows medium or high confidence, and it is always labeled a temporal association, not proof of causation.
Can the AI make up nutrition numbers?
No. A photo estimates portions, gram ranges, never calories directly. Nutrition is always calculated from verified per-gram data, and matches below a confidence threshold are queued for you to confirm or edit before anything is saved.
What happens to my data?
Meals, symptoms, and preferences stay tied to your account only. Food lookups send a search term or barcode to services like USDA and Open Food Facts, never your name, email, or health data. Export everything or delete your account permanently from Settings, any time.
Does GutLens replace my doctor or dietitian?
No. GutLens is for tracking and context, not treatment. Always talk to a qualified healthcare provider or registered dietitian before making dietary changes, especially during elimination or reintroduction phases.
