Grove vs FiberUp: Which Fiber Tracker Should You Use?

Grove and FiberUp are both dedicated fiber-tracking apps for iPhone, and neither is a knockoff of the other. Grove is the better fit if you want the full USDA food database, gut-symptom tracking, and a privacy-first app that keeps your data on your device. FiberUp is the better fit if you want barcode scanning and every feature included at download.

Most fiber apps are really calorie apps with a fiber number bolted on. Grove and FiberUp are two of the few that treat fiber as the main event. If you have landed on this page, you have probably narrowed it down to these two and want a straight answer about which one to install. This is that answer, written by the person who builds Grove, so read the FiberUp credit as genuine. It wins in real ways, and I will tell you exactly where.

What Grove and FiberUp have in common

Before the differences, the shared ground. Both apps are built around one job: help you hit a daily fiber target and see your progress at a glance. Both pull their nutrition numbers from USDA data, so a gram of fiber in one is a gram of fiber in the other. Both give you a clean progress ring instead of a spreadsheet. And both are made for people who have already decided that fiber matters and want to stop guessing whether they ate enough of it.

If you are still figuring out your number, our guide on how much fiber per day is worth reading first, because the app you pick matters a lot less than actually hitting the target.

Where FiberUp wins

Two things stand out, and they are real advantages, not consolation prizes.

Barcode scanning. This is FiberUp's clearest edge. Point your camera at a package, and the fiber count fills itself in. If a big share of what you eat comes with a barcode on it, cereal, bread, protein bars, packaged snacks, that scan-and-go flow is faster than searching by name. Grove does not have barcode scanning yet. I am not going to pretend otherwise. It is on the list, but today FiberUp does this and Grove does not.

Plant-count tracking. FiberUp counts how many different plants you eat, which is the metric behind the 30 plants a week idea that gut researchers keep pointing to. Fiber quantity and plant variety are related but not the same thing, and FiberUp gives variety its own scoreboard. If diversity is the habit you are trying to build, that is a thoughtful feature.

FiberUp also keeps everything in one bucket at download, with no subscription tier to think about. For some people, that simplicity is the whole selling point, and that is a fair reason to choose it.

Where Grove wins

Grove's advantages come down to depth, breadth, and what it can see about your body.

The food database is not close. FiberUp works from roughly 120 foods. Grove runs on the full USDA FoodData Central database, which is thousands of foods deep. The gap shows up the moment you eat something specific. Lentil pasta, a particular cut of squash, a regional dish, a restaurant salad rebuilt from its parts. On a 120-food list, you end up rounding to the nearest thing and quietly logging the wrong number. On the full database, the actual food is usually there. For a tool whose entire value is an accurate daily total, database size is not a nice-to-have. It is the product.

It tracks your gut, not just your grams. This is the feature no other fiber app has. Alongside fiber, Grove lets you log bloating, digestion, energy, and mood. Over a few weeks that turns "I think fiber helps me" into something you can actually see, because you can line up how you felt against what you ate. Fiber is a means to an end, and the end is how your gut feels. Grove is built to close that loop.

It respects your privacy by default. Grove runs on-device. No account to create, no ads, no data broker in the middle. Your food log is yours. In a category built on health data, that is not a small thing.

Grove also personalizes your daily target using USDA and IOM guidance, logs foods in natural portions like "1 medium avocado" instead of forcing you into grams, syncs with Apple Health, and keeps a daily streak going to make the habit stick. If you want ideas for what to actually log, our list of high-fiber foods pairs well with either app.

Which fiber tracker should you use?

Here is the honest split.

Choose FiberUp if you eat a lot of packaged food and want barcode scanning, you care most about plant variety, or you simply want every feature in one place at download with no subscription decision.

Choose Grove if you want the real USDA food database instead of a short list, you want to track how your gut feels alongside your fiber, or you care about a privacy-first app that keeps your data on your device. Grove+ is there when you want the deeper history, trends, and gut insights, but the core tracker stands on its own.

Both are legitimate apps made by people who take fiber seriously. You will not go wrong with either. The question is just which trade-off fits your life, faster packaged-food logging on one side, a deeper database plus gut tracking on the other.

Frequently asked questions

Is Grove a good FiberUp alternative?

Yes, especially if FiberUp's roughly 120-food list has left you rounding to the closest match. Grove runs on the full USDA FoodData Central database and adds gut-symptom tracking, which FiberUp does not have. The main thing you give up is barcode scanning, which Grove has not shipped yet.

Does Grove have barcode scanning like FiberUp?

Not yet. This is FiberUp's clearest advantage today. If scanning packaged foods is central to how you want to log, FiberUp is the stronger pick right now. If most of what you eat is whole foods or made from components, Grove's larger database usually finds the item anyway.

What can Grove track that FiberUp cannot?

Gut-health symptoms. Grove lets you log bloating, digestion, energy, and mood next to your fiber, so you can see whether eating more fiber actually changes how you feel. FiberUp focuses on fiber quantity and plant count and does not track symptoms.

How much does Grove cost compared to FiberUp?

Grove downloads at no cost, with an optional Grove+ subscription ($4.99 per month or $29.99 per year) that unlocks full history, weekly trends, a monthly calendar, and gut insights. FiberUp includes its features at download with no subscription. If you never want to think about a subscription, that is a point in FiberUp's favor.

Which app has more foods?

Grove, by a wide margin. FiberUp works from around 120 USDA foods, while Grove uses the full USDA FoodData Central database of thousands of foods. For accurate daily totals, that difference matters most when you eat something specific or less common.

Can I use both apps?

You can, but you probably should not. Logging the same meals twice is the fastest way to quit tracking altogether. Pick the one whose trade-offs fit your eating habits and give it two weeks before you judge it.

The bottom line

FiberUp is a solid app with a genuine edge in barcode scanning and plant-count tracking. Grove is built for depth: the full USDA database, gut-symptom tracking that no other fiber app offers, and a privacy-first design that keeps your data on your phone. Match the app to how you eat and you will pick correctly.

If the deeper database and gut tracking sound like what you have been missing, you can get Grove on the App Store and see where you land on today's fiber before dinner.
