Grove vs Cronometer for Fiber and Gut Health

By James McKinney

I build Grove, so factor that in. Cronometer is the better app if you want to see everything your food contains, because it tracks 80+ nutrients from a curated database and has the strongest accuracy reputation in this category. Grove is the better app if fiber is the one thing you are working on, because logging takes about ten seconds, the fiber number owns the screen, and your gut symptoms sit right next to it.

Cronometer is the app I recommend most often when someone tells me Grove is not enough for them. That is not politeness. If you are managing a real nutrient question, Cronometer is a serious tool and Grove is not trying to be one.

But most people who go looking for a fiber app do not have a nutrient question. They have a gut problem. They feel bloated most afternoons, or they are trying to fix a constipation pattern, or they read that only about 7 percent of US adults hit the recommended fiber intake and wondered whether they were in the 93 (Dietary Guidelines for Americans). Those people want one number, every day, with as little ceremony as possible.

Those are two different apps. Here is the honest split.

What Cronometer is genuinely better at

Data quality. This is Cronometer's whole identity and it earns it. Its database is curated rather than open to anyone, and it leans on lab-verified sources. When you are counting something you cannot see, knowing the source of the number is most of the value.

Nutrient depth. Cronometer tracks more than 80 nutrients. Vitamins, minerals, amino acids, fatty acids, and fiber alongside them. If you are vegan and watching B12 and iron, or you are on a medically supervised plan, or you just like knowing your magnesium, nothing on the fiber-app shelf comes close. Grove does not try.

It exports. If you work with a dietitian or a doctor and need to hand over real data, that matters more than any feature I could ship.

It has a no-cost tier. You can track without paying, and Gold is $10.99 a month or $59.99 a year as of August 2026 if you want the extra layers.

So if you read that list and thought yes, that is what I want, stop here and go get Cronometer. I mean that. Grove would be a downgrade for you.

Where Grove is better

Speed, and speed compounds. Grove is a search box, a portion, and a tap. Search "lentils," pick one cup, done. Ten seconds. Cronometer asks for more because it is capturing more, and every extra field is a small toll you pay three or four times a day.

Nobody quits tracking because the data was too accurate. They quit because logging lunch felt like paperwork. If your fiber habit dies in week two, the 80 nutrients you could have seen are worth exactly nothing.

Fiber owns the screen. Open Grove and today's fiber is the first and biggest thing you see, against your goal. Defaults are 34 grams a day for men and 25 for women, and you can set your own. In Cronometer, fiber is a well-measured row in a long, dense list. The number is better. The visibility is worse. For a habit you are trying to build, visibility is what does the work.

Gut symptoms sit next to the grams. This is the feature I would not trade. Grove lets you check in on bloating, digestion, and energy alongside your fiber. Over three or four weeks you get two lines on the same timeline, and you can see whether the grams are buying you anything.

Cronometer will tell you exactly what you ate. It will not tell you how you felt. For most people chasing fiber, how they felt is the entire point.

No account, and your food log stays on your phone. Grove has no sign-up. Your meals live on your iPhone. The only thing that leaves is your daily fiber total, written to Apple Health if you switch that on. Cronometer is a cloud account by design, which is what makes syncing and export possible. Reasonable trade, opposite directions.

Price, for this one job. Grove is $4.99 a month or $39.99 a year as of August 2026, with a 7-day free trial on the annual plan. Cronometer Gold is $10.99 a month or $59.99 a year. Cronometer is doing far more, so the higher price is fair. But if fiber is your only question, you are paying roughly double for 79 answers you did not ask for.

I will be straight about Grove's model too. New users need a subscription once the 7-day trial ends. There is no permanent no-cost tier. Cronometer has one, and for some people that alone decides it.

What Grove does not do

No calories. No protein, carbs, or fat. No vitamins or minerals. No export. No web app. If you need to hand a spreadsheet to a clinician, Grove is the wrong tool and I am not going to pretend otherwise.

The case for using one, not both

I have watched people try to run both. Cronometer for the full picture, Grove for the daily fiber view. It almost never lasts, because logging every meal twice is exhausting and one of the two apps quietly goes stale.

Pick based on the question you are actually trying to answer this month:

  • "Am I short on any nutrient?" That is Cronometer.
  • "Did I hit my fiber today, and is my gut getting better?" That is Grove.

If your answer changes in six months, switch apps. It is a subscription, not a marriage.

Which one should you pick?

Pick Cronometer if you want 80+ nutrients, you value the most rigorously sourced database available, you need to export data for a dietitian or doctor, or you are managing a health condition where several nutrients matter at once.

Pick Grove if fiber is the number you are trying to move, you want logging to take ten seconds so you actually keep doing it, you want to see your bloating and digestion charted next to your intake, or you want an app with no account that keeps your food log on your device.

Once you have picked, the next problem is what to eat. Our high-fiber foods list has the per-serving numbers, and the 30 plants a week guide covers variety, which matters alongside raw grams.

Frequently asked questions

Does Cronometer track fiber?

Yes, and it tracks it well. Fiber is one of more than 80 nutrients Cronometer records, drawn from a curated and largely lab-verified database. The catch is presentation rather than accuracy. Fiber appears as one row in a long nutrient list, so it takes more effort to see at a glance each day.

Is Cronometer more accurate than Grove?

For nutrients in general, Cronometer has the stronger reputation, because its database is curated and covers 80+ nutrients from verified sources. For fiber specifically, both apps work from well-sourced data. Grove uses USDA FoodData Central, the same public database that underpins much of US nutrition research.

Is Grove cheaper than Cronometer?

Yes, as of August 2026. Grove is $4.99 a month or $39.99 a year with a 7-day free trial on the annual plan. Cronometer Gold is $10.99 a month or $59.99 a year, and Cronometer also has a no-cost tier that Grove does not offer. Cronometer does considerably more for the extra money.

Which app is better for gut health?

Grove, for one reason. It records gut symptoms such as bloating, digestion, and energy on the same timeline as your fiber intake, so you can see whether eating more fiber changes how you feel. Cronometer tracks what you ate in far more detail but does not track symptoms at all.

Can I export my data from Grove?

No. Grove keeps your food log on your iPhone with no account and no server, and there is no export. Your daily fiber total can be written to Apple Health if you enable it. If you need to share detailed records with a dietitian or doctor, Cronometer is the better choice.

The bottom line

Cronometer is the more capable app, and I would recommend it without hesitation to anyone who wants the full nutrient picture or needs to share data with a clinician.

Grove is the more likely app to still be open on your phone in October. It does one thing, it does it in ten seconds, and it keeps a record of how your gut felt while you did it.

If that is what you want, get Grove on the App Store and see where today lands.
