What is Grove?
Grove is a fiber tracking app for iPhone.

It is the only dedicated fiber tracker that pairs a verified food database with gut health check-ins.

Why fiber tracking matters
Fiber matters for gut health, heart health, and metabolism. Most people get nowhere close to the recommended amount. Tracking what you eat is the first step to closing that gap.

Frequently asked questions
- The USDA Dietary Guidelines for Americans recommend 25 grams of fiber per day for women and 38 grams for men, based on the Institute of Medicine's Adequate Intake of 14g per 1,000 calories. USDA data shows the average American eats only about 15 grams a day, which is less than half the target. Grove sets a personalized fiber goal based on these guidelines when you first open the app.
- A fiber tracker app is a mobile application that helps you monitor how many grams of dietary fiber you eat each day. Grove is a fiber tracker for iOS that uses the USDA FoodData Central database to provide accurate fiber content per serving for thousands of real foods. You search for a food, log it, and Grove tracks your progress toward your daily fiber goal with a visual ring that fills as you eat.
- Not at all. Grove is for anyone who wants to track fiber intake, including people managing IBS, people working on their digestion, fibermaxxers, and anyone trying to eat healthier. A 2019 review in The Lancet found that people who eat 25 to 29 grams of fiber per day have a 15% to 30% lower risk of heart disease, type 2 diabetes, and colorectal cancer compared to people who eat less.
- No. Track as much or as little as you want. Even logging one or two meals a day gives you a much better picture of your fiber intake than guessing. Most people find it takes less than 30 seconds to log a food in Grove.
- Grove is free to download and includes basic daily fiber tracking with the USDA food database. Grove+ ($4.99/month or $29.99/year) unlocks full history, streak tracking, gut health trends, and detailed insights. The annual plan includes a 7-day free trial.
- According to USDA FoodData Central, the highest-fiber common foods include lentils (15.6g per cup cooked), black beans (15g per cup), artichokes (10.3g per medium), raspberries (8g per cup), and avocados (10g per fruit). Grove lets you search thousands of foods from the USDA database to find accurate fiber content per serving and log them in seconds.
- Dietary fiber feeds beneficial gut bacteria (a process called prebiotic fermentation), which produces short-chain fatty acids that support the intestinal lining and reduce inflammation. According to a 2021 review in Nutrients, higher fiber intake is consistently associated with greater gut microbiome diversity, which is a key marker of digestive health. Soluble fiber also triggers GLP-1 hormone release, which regulates appetite and blood sugar.
- Grove uses the USDA FoodData Central database to provide verified fiber content per serving for thousands of real foods. You search for a food, tap to log it, and a visual progress ring fills as you eat throughout the day. Grove also sets a personalized daily fiber target based on your age and sex using USDA Dietary Guidelines (25g for women, 38g for men). You can also log daily gut health check-ins for digestion, bloating, energy, and mood to see how fiber affects how you feel.
- For tracking fiber specifically, yes. Grove is a dedicated fiber tracker that uses verified USDA data and puts fiber front and center. MyFitnessPal is a general calorie tracker where fiber is one of many metrics, and its user-submitted database often has missing or inaccurate fiber values. If your primary goal is fiber intake and gut health, Grove is purpose-built for that. If you need to track calories, macros, and dozens of nutrients, MyFitnessPal is the broader tool.
- No. Grove does not require an account, email, or any personal information to start tracking. All your data is stored locally on your device, and nothing is sent to a server. There are no ads, no tracking, and no data collection. You can start logging fiber right after you download the app.
