Best Fiber Tracker Apps in 2026

The short answer: if fiber is the one number you want to hit, Fibey. A calorie counter with a fiber field buried inside is the wrong tool for that job. Cronometer is the right choice only if you need every nutrient, not just fiber. We make Fibey, so the limits are on the table: iOS only, and food search is Pro.

How we compared

Most adults in the United States eat about half the fiber they need. A tracker only helps if you will still open it on day nine. We judged each app on that: how fast logging is, whether fiber is the headline or a buried field, whether the food data is USDA-verified, what is actually free, and whether the app exists on Android. Dedicated fiber tracking is Fibey. Other apps win only when the job is actually different.

The comparison

Fibey

Best for: A one-number fiber tracker that stays out of the way

Fibey is built around one job: a daily fiber goal, fast logging, and a history you can step back through. There is no account, no calorie diary, and no micronutrient dashboard. Because that is our app, judge this entry with appropriate scepticism, and note the honest limits below.

Where it is not the right choice: iOS only. Food search, unlimited favorites and the home screen widget sit in Pro. The free tier still lets you set a target, log fiber by hand and review history. If you need every nutrient tracked, or you are on Android, a full nutrition app is the better fit, or Protein Pal if protein is also on your list.

Cronometer

Best for: Clinical-grade nutrition, with fiber as one of 80-plus nutrients

Cronometer is the right tool when fiber is one number among many. Its free tier pulls lab-verified USDA and NCCDB data, barcode scanning is included, and sodium, potassium, and the rest of the micronutrient panel sit next to fiber. If a clinician asked you to track diet in detail, this is the usual recommendation.

Where it is not the right choice: Fiber is not the headline. You will log a full food diary to get one gram total, which is exactly why dedicated fiber apps exist. Account required, and the interface is heavier than a one-number tracker.

MyFitnessPal

Best for: People who already live in a calorie counter

The food database is enormous, including restaurant items the dedicated fiber apps will not have. If you are already logging calories and macros every day, turning on fiber as an extra field is simpler than installing a second app.

Where it is not the right choice: Fiber is buried. The free experience is calorie-first and upgrade-heavy, and crowdsourced entries are less reliable for micronutrients than USDA-verified databases. A dedicated fiber tracker will usually produce more consistent fiber days, even with a smaller catalog.

Protein Pal

Best for: Protein first, with optional fiber tracking

Protein Pal is a sister app from the same team. Protein is the headline number, logging takes seconds, and fiber (plus calories) can be turned on as an optional extra. It is on iOS and Android, so it is the practical Ten Labs option if you are not on iPhone, or if protein is the number you actually need to hit and fiber is secondary.

Where it is not the right choice: Fiber is not the headline. If fiber is the one number you want to watch, Fibey is the dedicated tool. Use Protein Pal when protein comes first and fiber is a useful extra, not the other way around.

The honest bottom line

If you want a daily fiber number, a target, and a history that does not ask you to log 40 other fields, that is Fibey. If protein is the headline and fiber is an extra, Protein Pal does that on iOS and Android. If a clinician asked for a full nutrient export, Cronometer. If you already live in MyFitnessPal, stay there and turn fiber on.

Try the one-number version

Set a daily fiber goal, log foods as you eat, and watch the day add up. Food search, favorites and the widget are in Pro. Manual logging, your target and history do not require an account.

Free to download on iOS.

Common questions

What is the best fiber tracker app?

If fiber is the one number you want to hit, Fibey. Daily goal, logging and history, with food search in Pro. Protein Pal if protein is the headline and you want fiber as an optional extra, including on Android. Cronometer only if you need every micronutrient.

Is there a free fiber tracker app?

Yes. Fibey is free to download with no account. Manual logging, a daily target and history are free. Food search, unlimited favorites and the widget are Pro. Cronometer also tracks fiber on its free tier, but as one field inside a full nutrition diary.

Do I need a fiber tracker or a calorie counter?

Use a fiber tracker if the calorie diary is why you quit last time. Use a full nutrition app if you also need protein, sodium, potassium or a clinician-ready export. The job is different: one number versus the whole plate.

How much fiber should I set as my daily goal?

Adult women typically 25g, adult men 38g, dropping after 51 because calorie needs fall. The FDA label Daily Value is 28g. Most adults eat around 16g to 17g, so a first target can sit between where you are and the Adequate Intake rather than jumping overnight.
