7 Best Fiber Tracker Apps for iPhone in 2026
Most Americans eat less than half the recommended daily fiber. These are the best apps to help you track your intake, build better habits, and actually hit your fiber goals.
I tested every fiber tracking app I could find on the App Store. Some are purpose-built for fiber, others are general nutrition trackers that happen to include it. Here's how they stack up.
Quick Comparison
| App | Price | Fiber-Focused | Barcode Scanner | No Account |
|---|---|---|---|---|
| FiberUp | Free | Yes | Yes | Yes |
| Plant Power | Free | Yes | No | Yes |
| Fiber Counter and Tracker | One-time $3.99 | Yes | Yes | Yes |
| Fiber Tracker & Counter | Free / Pro $4.99 | Yes | No | Yes |
| Cronometer | Free / $49.99/yr | No | Yes | No |
| MyFitnessPal | $79.99/yr | No | Yes | No |
| CareClinic | Free / Premium | No | No | No |
1. FiberUp
FiberUp is a dedicated fiber tracking app built specifically for people who want to monitor their daily fiber intake without the complexity of a full nutrition tracker. It has a 120+ food database with USDA-verified fiber data, a barcode scanner powered by Open Food Facts, and a daily progress ring that makes it easy to see where you stand at a glance.
What sets it apart is the focus. There's no calorie counting, no macro tracking, no meal planning - just fiber. You open the app, log what you ate, and watch your ring fill up. It also tracks your weekly plant count, which is based on gut microbiome research showing that eating 20+ different plant species per week improves gut diversity.
No account required. No ads. No subscription. You download it and start tracking immediately.
Pros
- 100% free, no paywalled features
- No account or sign-up required
- Barcode scanner for packaged foods
- Weekly plant count tracking
- Clean progress ring UI
- USDA-verified fiber data
Cons
- iOS only - no Android version
- Smaller food database than general trackers
- No calorie or macro tracking
2. Plant Power (Fiber Tracker)
Plant Power takes a different approach to fiber tracking - it focuses on plant diversity rather than raw fiber grams. The app monitors your consumption of fruits, vegetables, legumes, whole grains, and other plant sources, built around the idea that a varied plant-based diet is the best path to a healthy gut microbiome.
It has some impressive features: you can photograph your meal and the app uses AI to detect plant-based ingredients, or use voice logging to add foods by speaking. It also includes gamification with streaks, challenges, and milestones.
The main limitation is that it doesn't have a barcode scanner, so packaged foods require manual entry. It's also more focused on plant variety than precise fiber gram tracking.
Pros
- Completely free, no ads
- AI photo recognition for meals
- Voice logging
- Gamification (streaks, challenges)
- Reusable meals for quick logging
Cons
- No barcode scanner
- Focused on plant count, less on exact fiber grams
- Less useful for tracking packaged foods
3. Fiber Counter and Tracker
Fiber Counter and Tracker is one of the older dedicated fiber apps on the App Store (since 2014). It takes a straightforward approach: record food using the barcode scanner, search, dictation, or favorites. One-time purchase, no ads, no subscription, no registration.
The one-time pricing model is refreshing in a world of subscriptions. You pay once and get the full app. The interface is functional but dated compared to newer apps. If you want something no-frills that just works, this is a solid choice.
Pros
- One-time purchase - no subscription
- Barcode scanner included
- Dictation for food logging
- No account required
Cons
- Dated interface design
- $3.99 upfront cost
- No weekly analytics or trends
4. Fiber Tracker & Counter
Fiber Tracker & Counter is the app that currently ranks highest on Google for "fiber tracking app." It has a clean, ultra-simple interface: set a daily fiber target and quick-add grams as you eat throughout the day.
The free version is bare-bones - you can set a target and manually add fiber grams, but that's about it. To search foods for their fiber content, add more than 3 favorites, or use the home screen widget, you need to upgrade to Pro ($4.99). Some users find this paywall frustrating for what feels like basic functionality.
Pros
- Extremely simple interface
- Quick-add for manual fiber entry
- History view for tracking trends
- Home screen widget (Pro)
Cons
- Food search locked behind paywall
- Only 3 free favorites
- No barcode scanner
- Free version is very limited
5. Cronometer
Cronometer isn't a fiber-specific app - it's a full nutrition tracker. But it's the best general tracker for fiber because of its data accuracy. Every user-submitted food is reviewed by Cronometer's curation team before being added, and it tracks over 80 micronutrients including fiber.
You can view your fiber intake under the carbohydrates section in your daily report, set custom fiber targets, and see your top fiber sources. The free version includes fiber tracking, though the Gold plan ($49.99/year) adds features like custom biometrics and fasting timers.
The downside is complexity. If you just want to track fiber, Cronometer is overkill. You'll be logging full meals with calories, macros, and dozens of micronutrients when all you really wanted to know was "did I eat enough fiber today?"
Pros
- Highly accurate, curated food database
- Fiber tracking included in free version
- Tracks 80+ micronutrients
- Barcode scanner
- Available on iOS and Android
Cons
- Overkill if you only care about fiber
- Requires account creation
- Steeper learning curve
- No soluble/insoluble fiber breakdown
6. MyFitnessPal
MyFitnessPal is the most popular nutrition app in the world with the largest food database (11+ million foods). It can track fiber - but only if you pay for Premium at $79.99/year. The free version shows calories and basic macros but hides fiber behind the paywall.
If you're already a MyFitnessPal Premium subscriber tracking calories and macros, adding fiber to your dashboard makes sense. But paying $80/year just to track fiber when free dedicated apps exist doesn't.
Pros
- Largest food database (11M+ foods)
- Barcode scanner
- Meal scanning with AI
- Integrates with most fitness devices
Cons
- Fiber tracking requires Premium ($79.99/yr)
- Not fiber-focused - buried in nutrition data
- Requires account creation
- Free version has ads
7. CareClinic
CareClinic is a health management app that includes dietary tracking with a built-in food library. It's designed for people managing chronic health conditions - you can track medications, symptoms, and nutrition (including fiber) in one place.
If you're tracking fiber because of IBS, Crohn's, or another digestive condition and need to correlate fiber intake with symptoms, CareClinic's approach makes sense. For general fiber tracking, it's more complex than needed.
Pros
- Tracks fiber alongside symptoms and medications
- Good for chronic condition management
- Built-in food library
Cons
- Not fiber-focused
- No barcode scanner
- Requires account creation
- Premium features require subscription
How to Choose the Right Fiber Tracker
The best app for you depends on what you're trying to do:
- If you just want to track fiber and nothing else: FiberUp or Fiber Tracker & Counter. Both are simple and focused. FiberUp is free with more features; Fiber Tracker & Counter is simpler but paywalls food search.
- If you care about plant diversity for gut health: FiberUp (plant count tracking) or Plant Power (plant-first approach with AI photo recognition).
- If you want fiber tracking as part of full nutrition logging: Cronometer is the most accurate. MyFitnessPal has the biggest database but costs $80/year.
- If you're managing a digestive condition: CareClinic lets you correlate fiber intake with symptoms.
How Much Fiber Do You Need Per Day?
Before you start tracking, here's what you're aiming for. The FDA recommends 25g of fiber per day for women and 38g for men, based on a 2,000-calorie diet. Most Americans eat only 10-15g per day - less than half the minimum.
High-fiber foods that can help you close the gap:
- Lentils: 15.6g per cooked cup
- Black beans: 15g per cooked cup
- Split peas: 16g per cooked cup
- Avocado: 10g per whole fruit
- Chia seeds: 10g per ounce
- Artichokes: 10g per medium artichoke
- Oats: 4g per serving
- Brussels sprouts: 4g per cup
A fiber tracker app makes it easy to see where you stand each day and identify which meals need more fiber-rich foods.
