What is Grove?
Grove is a fiber tracker for iPhone. It pulls fiber numbers from the USDA food database, starts you at a daily goal of 25g that you can change, and lets you log how your gut feels next to what you ate. It runs on iPhone with iOS 18.0 or later.
USDA food database
Fiber numbers come straight from USDA FoodData Central. Portions read like real life: 1 cup, 1 medium, ½ cup cooked.
Built around fiber
Grove tracks fiber and nothing else. Your day climbs a hill as you eat, so you always know how far you are from today's goal.
Your gut, next to your food
Tell Grove how your gut feels with one tap a day. It lines your answers up with your fiber so you can see how they move together.
No account, no ads
Your log stays on your iPhone and, if you use iCloud, in your own iCloud account. Grove has no server that stores it.
Fibermaxxing is one of the biggest gut health trends of 2026
Whole Foods Market and Innova Market Insights both put fiber near the top of their 2026 food trend lists. Grove is built for people acting on it.

Watch your fiber climb the hill
Every food you log lands on the hill, and Grove walks toward your goal flag. The big number at the top is where you stand today.
Log it in one tap
The foods you eat most wait on Today. For anything else, search real foods from the USDA database or scan a barcode.
Pick a serving, skip the scale
Half, 1 or 2. A slice, a cup, a bowl. Grove works out the fiber, and grams are there if you want them.
See which days you hit it
One bar for each day. The dashed line is your goal, so the good days stand out and the short ones are easy to spot.
Say how your gut feels in one tap
Great, Good, Meh or Rough. Grove lines your answers up with your fiber, so you can see how the two move together.
Plus the stuff that keeps you going
Barcode scanner
Scan a packaged food and Grove pulls its fiber from Open Food Facts.
Apple Health, both ways
Grove reads and writes fiber, and saves gut symptoms like bloating and constipation.
Widgets and Siri
Home and lock screen widgets with one-tap logging. Ask Siri about your day or log a food.
iCloud sync
Sign in to iCloud and your log follows you to a new iPhone.
CSV export
Export your food log and check-ins as a spreadsheet file.
Light and dark
The hill follows your day: morning, noon, evening and night.

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.
Only 7%
of U.S. adults meet the recommended daily fiber intake
25–38g
recommended daily fiber intake (women 25g, men 38g)
15–30%
lower risk of heart disease, diabetes, and colorectal cancer with adequate fiber
~15g
average daily fiber intake for Americans, less than half the target
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 starts you at 25g a day, and you can change your goal any time.
- 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 on a hill that fills with the foods 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. A food you eat often takes one tap to log in Grove.
- You get the whole app for 7 days. No card and no account. After that, Grove needs a Grove+ plan to keep going. Grove+ is $7.99 a month or $49.99 a year. You choose a plan after your first 7 days. Grove+ is the whole app: one-tap logging, the USDA food search, the barcode scanner, your week, gut check-ins, widgets, Siri and Apple Health sync.
- 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. 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, pick a serving, and it lands on the hill on your Today screen. Foods you eat often can be logged again in one tap. Grove starts you at 25g a day, and you can change that goal. You can also log a one-tap gut check-in each day and see it next to your fiber in the Week view.
- 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 need an account, email, or any personal information. Your food log is stored on your iPhone. If you're signed in to iCloud, it also syncs through your own private iCloud account so it can move to a new phone. Grove has no server that stores your log. The app uses anonymous product analytics (TelemetryDeck and PostHog) to see which screens people use, and OneSignal to send reminders. No food or health data is sold or used for ads.
