Cronometer: Calorie Counter reviews

What users love and hate, from real reviews

Cronometer is a micronutrient tracker disguised as a calorie counter: it wins biohackers, diabetics and medically-driven users with data depth rivals don't offer, but that same depth turns basic calorie logging into operator's work, and an aggressive ad escalation pushes newcomers out before they ever reach the value.

What users love

The real hook is micronutrients, not calories: it retains medically-motivated users

Vitamins, minerals, omegas, fibre, sugar — this data layer turns food logging into a health-management tool, not a weight-loss one. It's what retains diabetics (A1C from 13 to 4.5), menopausal users and people whose doctor prescribed the tracker: they see what rivals don't show, so they don't leave.

I've been tracking macros for over 20 years. this is the best app and dials into micronutrients which helps manage menopause.

And watching my carb, calorie, and prrotien intake has gotten me from an A1C of 13 to an A1C of 4.5.

I love how thorough this app is; beyond even just tracking nutrition intake, but having a place to record other health metrics aswell.

The generous free tier is the funnel: users get hooked free, then pay voluntarily

Barcode scanner, custom recipes and full nutrient summaries are free — enough to make a user settle in. Many say outright: "used the free version for a year, then upgraded not because I had to, but because I love the app." The free tier doesn't cripple the product, it sells it.

I started with the free version and really started to enjoy it. Paid for the year subscription and I enjoy it even more.

This app is excellent, especially the free version which is robust — much better than My Fitness Pal's free version

Having a highly functional FREE version is really nice and helpful and the more I get into this, as time goes on I may invest in the paid version

Barcode scan and photo-add are the engine that makes logging stick

Free barcode scanning, and when an item isn't in the base, a photo of the front and the label that the app auto-fills from. This removes the friction that made users quit other trackers ("oops, this doesn't exist in our database"). It's frictionless input, not analytics, that gets people logging daily — and daily is the precondition for any result.

It's amazing to just take a picture when creating a product, I love how fast it finds a product when scanning, no loading eternally.

if its unknown you can simply take a photo of the front, and of the nutrition label and it will automatically fill it in for you

Wow I had my reservations going into tracking things like my cals and nutrients but they could not make it easier.

The app for MyFitnessPal refugees: it catches the exact moment a rival gets greedy

A huge share of users arrived after MFP stripped free features or Fitbit made logging "6x harder." Cronometer positions as "MFP before they got greedy" — and retains on exactly that contrast. It's a strategic moat: growth comes from rivals' mistakes, not marketing, and the refugees stay because the free tier here actually works.

The free features remind me of what My Fitness Pal used to be before they got greedy.

started trying this since MyFitnessPal won't let me log in anymore since their last update... I'm discovering that this app has better features!

Seamless tracker sync — what keeps the data-driven users in

Integration with Garmin, Withings, Fitbit pulls in calories burned and biometrics and dynamically adjusts the day's calorie budget. For a user who's built a closed loop of eat-burn-weigh, that loop is the product: one user hit 10% body fat precisely on it. The hardware tie-in turns a food tracker into a body-management system.

The functionality to connect with smartwatches for adding activity and adjusting live the calorie budget is the best thing ever.

It works quite well with my Garmin fitness tracker to add calories to my day after a good workout.

Synchronises well with Garmin devices (and presumably other smart trackers) for more accurate calorie expenditure, sleep, and activity tracking.

The learning curve filters out novices, but it's what forges the advanced, loyal user

The interface isn't intuitive at first, adding custom food needs an "operator's manual," and some features require googling. This sheds casual users — but those who cross the threshold call the "highly customizable" dashboard "pure genius" and stay for years. The entry barrier acts as a filter: it scares off the casual crowd and keeps the people who genuinely need the depth.

The fact that it is HIGHLY customizable is pure genius. A lot of thought clearly went into it.

There is a learning curve, but worth it.

The interface takes some getting used to, but after that it's easy.

Weak spots

What users hate

Ads kick in on day 4 — the product breaks the very habit it just built

Ads don't appear at first — they switch on after a few days, exactly once the user is hooked on logging. And they arrive full-screen, mid-entry, stealing focus and the keyboard. This isn't "too many ads," it's a deliberate bait-and-switch: the product waits for the habit to form, then attacks that habit to force the subscription. The effect backfires: users describe wanting to uninstall, not to buy.

Especially because they don't show up for the first few days.

At day 4, the fullscreen timed ads show up multiple times a day, some of which requires interaction. The app should not bait and switch.

Bait and switch. Works great for a week then you get interrupted with full screen ad spam.

The food database is the retention ceiling: regional gaps push out non-Americans

The app's strength is data accuracy, but it's also its weak spot: for Indian, Punjabi, South Indian, Algerian and UK dishes the database barely exists. A non-US user hits constant manual food creation — and the logging they came here to simplify becomes work. Regional food gaps are the quiet churn channel outside North America.

the Indian and Punjabi food database is very limited. Many homemade dishes and local brands are missing, so logging meals becomes time-consuming.

it never guessed the food correctly once, it's horrid edit: the issue is that it's traditional Algerian food, and either that's not in the database

some South Indian dishes are not available while updating my diary entries. Kindly consider adding more South Indian dishes

The app miscounts calories itself — and that kills trust in paying

A known bug: when logging multi-component meals, total calories and macros are computed wrong and the user has to check the math by hand. For a product whose one basic job is "to count," that's fatal — people say outright it's why they didn't buy Pro. An error in the core voids the whole micronutrient superstructure on top of it.

the one thing this app is supposed to do is count and it doesnt do that well. Its a known bug where it will mis calculate total calories and other macros with meals if your not checking the math

Saying some foods have double the sodium inconsistencies in niacin and calories incomplete information total BS

but the main things is that it's off by hundreds of calories which is a absolutely no no.

You can't set a calorie goal manually — the app imposes its own plan on people who don't want it

The app derives the calorie goal from profile data, and manual override is either hidden or broken. For a user who just wants to "track macros" against a specific doctor's or dietitian's advice, this turns the tool into an obstacle: they either fight imposed goals or start anxiously obsessing over them. Control over your own target is exactly what the medically-driven (not weight-loss) segment loses.

The biggest turn off is that you cannot manually set your calorie target. The app determines your calorie goal based off profile information.

Instead, I ended up obsessing over goals the app made for me, which I had little control over and weren't what I needed.

Could not set individual nutrient targets.

You can't edit a single ingredient in a saved recipe — for daily users this compounds into pain

To change one ingredient's weight in a saved recipe (20g → 5g) you must delete the old entry and re-add a new one. For people who cook their own recipes daily and log meal prep — the most loyal, paying segment — small friction multiplied by frequency becomes "pulling teeth." The regression stings more because editing used to work.

If I want to edit one item, for example, from 20g to 5g, I now can't select the item and make the change. I now have to re-add the item with the new weight and then delete the old entry.

If I make a recipe, I should just be able to adjust the ingredients not add and delete the ingredients.

please let me adjust a recipe every time I log it. I don't have the same ingredients everyday, and it's exhausting to edit the recipe

Health Connect double-counts calories and meals — the product breaks on someone else's migration

After Fitbit's move to Google Health Connect the integration turned hostile: meals and activity get duplicated, full BMR is added on top of the estimate — and the calorie budget becomes meaningless. The app's strength (hardware sync) turns against it when the ecosystem shifts underneath. Users can't tell Google's fault from the app's — and they leave the app.

Also, like the last review I also noticed that it was logging activity twice. It logs from the Fitbit & from Health Connect.

syncs horribly with the Google health app by duplicating meals and resets the water after years of use had to delete

cronometer adds the full bmr calorie burn on top of what it already estimates, making the calorie goal useless.

The rigid breakfast-lunch-dinner structure loses people who eat differently

You can't add an extra meal (brunch, a second dinner for 5-meals-a-day eaters), there's no multi-add into one meal, and you can't copy yesterday's breakfast in one tap — even though people eat the same things in streaks. The default day model is tuned for an average user and creates small daily friction for anyone whose eating pattern doesn't fit three slots.

just wish I could add additional meals, like brunch and tea, as some of us eat 5 meals a day.

I need a multi add option under breakfast lunch dinner.

One recommendation is to include a button to copy the last breakfast, lunch, or dinner. We all eat the same things in a row.; happens all the time.

Default nutrient targets carry a dietary stance — advanced users argue with the app's philosophy

By default the app steers toward a high-carb model (269g carbs/day as default), and for keto/low-carb users that's not a bug but an imposed stance they distrust. When a product is deeply about nutrients, its default recommendations read as a health claim — and part of the advanced, most valuable audience treats them as an ideological conflict.

A target of 269 grams of carbs per day, the app isn't tailoring a plan for your health—it is just blindly regurgitating the outdated, corporate-influenced food pyramid guidelines.

it will guide you toward a high-carb, low-fat framework that leads straight to energy crashes, brain fog, and intense hunger.

I am even able to track added sugar in my diet. Highly recommend!

It's a desktop tool in a mobile skin — the data depth lives on the big screen

Veterans say it plainly: for all the data they prefer the web version, mobile is a compromise. The app doesn't rotate to landscape on tablets (where most people hold a tablet), there's no undo, charts are unreadable, and the 2022 redesign struck some users as a regression from a "super beauty app." The product is built around a rich desktop dashboard, and the phone screen is its bottleneck, not its home.

I prefer the Desktop version for all the data, but the mobile app works also great.

Designers apparently did not read the stats that the majority of tablet users hold tablets landscape 2. No undo 3. Hard to read odd charts

2022 "redesign" that turned the once super beauty app into 80's computer game style
