GutLens by DJ Applications
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.
Keep the details that make patterns useful.
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.
Built around how food actually affects you.
Three habits make the difference between logging data and understanding it.
Log without friction
Type a sentence, scan a barcode, search a product, or review a photo. GutLens parses natural language and reads packaging so logging fits the moment instead of interrupting it.
Connect meals and symptoms
Link a symptom to a meal directly, or let GutLens infer a likely window from timing. Every link is labeled direct or inferred, so you always know what was confirmed and what was estimated.
See the evidence, not just a verdict
Correlations are shown as an exposed rate against your own baseline, with a confidence tier attached, never a single number pretending to be certain.
What's actually running underneath.
Every screen is backed by a real pipeline, not a black box.
Meal logging
Describe a meal in a sentence, search a product, scan a barcode, or snap a photo. Ambiguous matches are flagged for a quick check instead of logged silently.
Photo review
A photo estimates gram ranges for what is on the plate. Nutrition is never guessed from the image, it is calculated from verified per-gram data once you confirm the portion.
Trends and patterns
Daily totals for calories, protein, carbs, fat, fiber, sugar, and sodium. Trigger-food ranking needs repeated occurrences and a real severity signal, not one bad day.
Coach
A conversational assistant with real tools: it searches food and nutrition sources, checks FODMAP and safety status, and confirms portions with you before logging anything.
Confident about the mechanics, honest about the limits.
Two things have to be true at once: useful signal, and no overstated certainty.
Evidence and trust
Grounded in real food data
Nutrition comes from USDA, Open Food Facts, and similar sources, or a deterministic per-gram calculation. Never an estimate invented by a language model.
Reviewable, not automatic
Photo and text matches only auto-accept above a high confidence threshold. Everything else is queued for you to confirm.
Uncertainty is disclosed, not hidden
“Estimated match” and “Portion assumed” style labels appear right where the number does, not buried in a settings page.
Not a diagnosis
Patterns are associations, shown with their confidence and limitations, never proof of causation. GutLens does not replace a doctor or registered dietitian.
Privacy
No ads, no behavioral tracking
GutLens does not collect location, device or ad identifiers, or behavioral analytics, and does not sell or profile your data.
Food lookups stay anonymous
Barcode and food-name searches send only the query text or barcode to services like USDA and Open Food Facts, never your name, email, or health data.
Your data, your control
Export everything in a portable format, or delete your account permanently, any time, from Settings.
Questions worth asking before you trust an app with your gut.
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.
