The best low FODMAP apps of 2026

The diet is one thing - looking up values, scanning products, and finding which FODMAPs are actually yours are different jobs.

The low FODMAP diet runs in three phases - a strict elimination, a structured reintroduction, and a long-term personalised diet - and no single app does all three equally well.

One app is the best reference for FODMAP values. Another is best for scanning packaged food in the supermarket. Another is best for a guided programme. And a different one is best for the part that actually matters most: finding which FODMAPs, and which foods, are yours - the job of the reintroduction phase.

So here are the best low FODMAP apps of 2026, each matched honestly to the job it does well.

The Best Low FODMAP Apps of 2026: Our Picks

1. Triggerbites: Best for Finding Your FODMAP Triggers

Price: Subscription with a 7-day free trial · Platforms: iOS (Android coming soon)

The low FODMAP diet narrows the field - but it doesn't tell you which FODMAPs are your problem, which foods, or at what dose. That's the whole point of the reintroduction phase, and it's exactly what Triggerbites is built to find.

You write what you ate in plain language, and the app extracts the ingredients, tags them by FODMAP group (fructans, GOS, lactose, fructose, polyols) and other compounds, and correlates them with your symptoms across delayed time windows. During reintroduction it shows how dose-dependent a reaction is - the single most useful thing to know when you're rebuilding your diet.

Standout features:

  • Natural-language logging by text, voice or photo
  • Ingredient extraction with FODMAP-group and compound tagging
  • Multi-window delayed-reaction analysis, up to 72 hours
  • Dose-dependence tracking - built for the reintroduction phase
  • PDF & CSV reports to share with a dietitian

Best for: Anyone doing the low FODMAP diet who wants to find their personal triggers and tolerances, not just follow a list.

The catch: iOS only for now. It's a tracker, not a FODMAP database - pair it with Monash for the lookups.

2. Monash FODMAP App: Best for Looking Up FODMAP Values

Price: One-time purchase · Platforms: iOS, Android

The Monash app is essential on the low FODMAP diet - not as a tracker, but as the definitive reference. Built by the team that created the diet, it holds the world's largest FODMAP food database, with traffic-light ratings and safe serving sizes, plus a basic symptom tracker and a challenge log for the elimination phase.

Standout features:

  • The authoritative FODMAP food database
  • Traffic-light ratings by serving size
  • 3-phase diet guidance and recipes
  • Basic symptom tracker and challenge log
  • One-time purchase, no subscription

Best for: Anyone on the low FODMAP diet who needs to look up the FODMAP content of foods.

The catch: It's a reference with a light diary - it tells you a food's FODMAP value, not whether that food is actually triggering you.

3. FODMAP Diet A to Z: Best Free Quick Reference

Price: Free · Platforms: iOS, Android

If you want a no-cost FODMAP lookup, FODMAP Diet A to Z is a solid free reference - a searchable food list with FODMAP ratings that covers the everyday foods most people need to check.

Standout features:

  • Free searchable FODMAP food list
  • Simple traffic-light style ratings
  • Covers common everyday foods
  • No subscription

Best for: People who want a free, fast FODMAP reference and don't need the full Monash database.

The catch: The food list isn't as exhaustive or as rigorously sourced as Monash, and it's a reference, not a tracker.


4. Spoonful: Best for Scanning Packaged Food

Price: Free, with an optional premium tier · Platforms: iOS, Android

The hardest part of the supermarket is the packaged aisle. Spoonful lets you scan a barcode and get a low-FODMAP verdict - and it's smart about products that contain a small amount of a high-FODMAP ingredient, which a strict ingredient scan would wrongly reject.

Standout features:

  • Barcode scanning with a low-FODMAP verdict
  • Handles small amounts of high-FODMAP ingredients sensibly
  • Personalised to other dietary needs
  • Speeds up packaged-food shopping

Best for: People who want help judging packaged and processed foods while shopping.

The catch: It's a shopping aid for barcoded products, not a tracker - and barcode coverage is strongest for US products.


5. Cara Care: Best for a Guided FODMAP Programme

Price: Free; paid 12-week programme (free on prescription in Germany) · Platforms: iOS, Android

If you'd rather be guided through the diet than self-direct it, Cara Care runs a structured 12-week low FODMAP programme with unlimited registered-dietitian chat - useful support for a diet that's genuinely easy to get wrong.

Standout features:

  • Guided 12-week low FODMAP plan
  • Unlimited registered-dietitian chat
  • Best/worst-day food dashboard
  • Low FODMAP recipes

Best for: People who want structure and professional guidance through the diet's three phases.

The catch: Tracking is meal-level, with no ingredient extraction. The free-on-prescription version is German-only.

6. mySymptoms: Best for Manual Reintroduction Tracking

Price: Subscription with a 7-day free trial · Platforms: iOS, Android

If you want maximum control over your reintroduction data - and you don't mind entering it yourself - mySymptoms is the most configurable tracker here, with correlation analysis you can tune across a 1-72 hour window.

Standout features:

  • Configurable 1-72 hour correlation analysis
  • Large barcoded food database
  • Detailed reports and trends
  • Bristol scale and wellness metrics
  • PDF & CSV export

Best for: Detail-oriented people who want to run a structured reintroduction and don't mind manual logging.

The catch: It's all manual - search, scan, build meals by hand - with a real learning curve. No AI extraction or FODMAP-group tagging.

The Bottom Line

Most people on the low FODMAP diet end up using two apps: Monash for the FODMAP lookups, and a tracker for the part the lookups can't do - finding which FODMAPs, which foods, and which doses actually trigger your symptoms.

That second piece is the whole goal of the diet. The elimination phase just clears the noise; the reintroduction phase is where you learn your real, personal, often surprisingly generous limits. That's what Triggerbites is built for: write your day, and let it find the pattern.

Live, love, log.
