The best food sensitivity apps of 2026
Food sensitivity isn't one thing - so the right app depends on what you're chasing.
"Food sensitivity" sounds like a single thing. It isn't.
It's an umbrella over several different mechanisms - lactose, FODMAPs, histamine, salicylates, and more - and the symptoms reach well beyond the gut: skin flares, headaches, congestion, fatigue, brain fog. Two people who both say "I'm sensitive to something" can be dealing with completely different biology.
That's why there's no one "best food sensitivity app." There's a best app for discovering what you react to, a best one for deep manual analysis, a best one for whole-body symptom tracking, and a best one for shopping once you know. Here are the strongest picks of 2026, matched honestly to the job.

The Best Food Sensitivity Apps of 2026: Our Picks
1. Triggerbites: Best for Discovering Your Sensitivities
Price: Subscription with a 7-day free trial · Platforms: iOS (Android coming soon)
The hardest part of a food sensitivity is the discovery - working out which foods, and which compounds inside them, your body reacts to. That's exactly what Triggerbites is built for.
You write what you ate in plain language, and it extracts the individual ingredients and tags them across more than 20 compound categories - FODMAPs, histamine, salicylates, lactose and more - then correlates them with your symptoms over delayed time windows. Because food sensitivities are usually about a compound hiding across many foods, that compound-level view is what turns "something I eat" into a real answer.
Standout features:
- Natural-language logging by text, voice or photo
- Automatic ingredient extraction and 20+ compound categories
- Multi-window delayed-reaction analysis, up to 72 hours
- Tracks symptoms beyond the gut - skin, head, energy
- Import old diaries and notes; PDF & CSV reports
Best for: Anyone trying to discover which foods or compounds they're sensitive to.
The catch: iOS only for now. It's a discovery tool, not a product scanner for the supermarket.

2. mySymptoms: Best for Deep, Manual Analysis
Price: Subscription with a 7-day free trial · Platforms: iOS, Android
If you want maximum control and statistical depth, 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 with histograms and trends
- PDF & CSV export and clinician sharing
Best for: Detail-oriented people who want depth and don't mind manual logging.
The catch: Manual data entry with a learning curve; no AI or compound tagging.
Go deeper: Triggerbites vs mySymptoms.
3. Bearable: Best for Whole-Body Symptom Tracking
Price: Free, with an optional premium tier · Platforms: iOS, Android
Food sensitivities often show up as skin, mood and energy symptoms, not just gut ones. Bearable is the best general tracker for that whole-body picture, with a genuinely generous free tier.
Standout features:
- Unlimited custom symptoms and factors
- Mood, energy, sleep and skin tracking
- "Experiments" to test interventions
- Correlation grid across all your factors
Best for: People whose sensitivity symptoms span the whole body, not just digestion.
The catch: It doesn't track food at ingredient level - meals are generic "factors" - so it's weaker at pinning down the specific food.
Go deeper: Triggerbites vs Bearable.
4. Endive: Best for a Simple Food Sensitivity Diary
Price: Free, with an optional Plus tier · Platforms: iOS, Android
If you want something clean and easy to keep up, Endive is a simple, well-designed food and symptom diary - calorie-free, with visual correlation graphs and a free tier to start.
Standout features:
- Simple food and symptom logging
- Visual correlation graphs
- Breaks known recipes into ingredients
- iOS and Android
Best for: People who want a simple, sustainable diary over deep analysis.
The catch: No compound tagging or explicit delayed-reaction windows; no import.
Go deeper: Triggerbites vs Endive.
5. Fig: Best for Shopping with Known Sensitivities
Price: Free, with an optional Fig+ subscription · Platforms: iOS, Android
Once you know your sensitivities, the daily challenge shifts to the supermarket. Fig lets you scan a product's barcode and instantly see whether it fits your dietary needs - low FODMAP, low histamine, gluten-free, a specific allergy, and thousands more.
Standout features:
- Instant barcode compatibility checks
- Supports thousands of diets and restrictions
- Compatible-food guides for stores and restaurants
- Profiles for the whole family
Best for: People who already know their sensitivities and want help shopping around them.
The catch: It assumes you already know what to avoid - it won't help you discover a sensitivity in the first place.

Which Food Sensitivity App Should You Choose?
Choose Triggerbites if: you want to discover which foods and compounds you react to - the hardest and most important step.
Choose mySymptoms if: you want deep, configurable, statistics-led analysis.

The Bottom Line
The journey of a food sensitivity has two halves: discovering what you react to, and then living around it. Fig is excellent for the second half. But the first half - the discovery - is where most people are stuck, and it's the harder problem.
That's what Triggerbites is built for: write your day, and let it extract the ingredients, tag the compounds, and surface the pattern - so "I'm sensitive to something" finally becomes "I'm sensitive to this."
Live, love, log.
