Quick Verdict
MyFitnessPal and Cronometer solve the calorie-tracking problem from opposite directions. MyFitnessPal is built around the largest food database in the consumer category — 14 million entries, mostly crowdsourced, with an opt-in verified filter for users who pay Premium. Cronometer is built around the most rigorously verified database — 1.3 million entries, USDA/NCCDB/manufacturer-anchored, with user submissions quarantined as a separate opt-in tier. Two different bets on what matters for an honest calorie count.
The structural argument for Cronometer on accuracy is: per-entry crowdsourcing noise compounds across a day of logging. A search for “grilled chicken breast” on MFP returns dozens of entries with kcal values varying ±15% per 100g. The user picks one, frequently the first result, and that variance becomes the daily total’s error floor. Cronometer’s verified-by-default approach removes this — the entries the user picks from already have known provenance.
The structural argument for MyFitnessPal is: a 14-million-entry database covers food the smaller verified database does not, particularly US chain restaurant menus and long-tail packaged goods. A decade and a half of crowdsourced coverage is a moat — Cronometer’s smaller curated database will not match it on raw breadth. For users who eat at chains frequently, the difference is practical.
Tally across 18 criteria: Cronometer 10, MyFitnessPal 5, Tied 3.
When MyFitnessPal Is the Right Choice
You eat at US chain restaurants frequently. MyFitnessPal’s restaurant database is best-in-class — Chipotle, Sweetgreen, Panera, regional chains — many of these are not in Cronometer at the same depth, and the manufacturer-published nutrition data MFP imports tends to be reliable for chain menus.
You log a lot of packaged grocery items by barcode. MFP’s barcode catalog is the largest in the consumer category. For someone shopping at a US grocery and scanning everything, MFP finds more codes.
You have years of historical data inside MFP that you do not want to abandon. Data portability between trackers exists but is imperfect; if your weight-loss journey is documented inside MFP, the cost of leaving is real.
You want the deepest fitness-tracker ecosystem (Apple Health, Garmin, Fitbit, Polar, Wahoo). MFP has had a head start on integrations and it shows.
When Cronometer Is the Right Choice
You care about per-entry accuracy. Verified-by-default is the structurally less noisy approach, and that compounds over months of logging.
You want micronutrient tracking. 80+ nutrients per food vs MFP’s handful is not a small difference. For users debugging an iron deficiency, B12 status, or omega-3 ratio, this is the category-leading product.
You are a quantified-self user, an RD, or working with one. Cronometer is the standard recommendation in these communities for reason.
You refuse to pay for a feature that should be the default (verified data). MFP paywalls the verified filter; Cronometer has verified-by-default in the free tier.
The Price Comparison
| Plan | MyFitnessPal | Cronometer |
|---|---|---|
| Free tier | With ads; verified filter / AI photo / recipes paywalled | With web ads; full calorie + macro + basic micros included |
| Premium monthly | $19.99 | $7.99 |
| Premium annual | ≈ $79.99 | $54.99 |
| Verified-entry default | Premium feature | Free tier |
| AI photo logging | Premium feature | Free tier (basic) |
Cronometer Premium is ~30% cheaper than MyFitnessPal Premium and includes features that MyFitnessPal locks behind Premium. For the value-per-dollar calculation, Cronometer wins clearly.
Bottom Line
Cronometer wins this head-to-head on accuracy, micronutrient depth, free-tier generosity, and value. MyFitnessPal wins on database breadth, US chain restaurant coverage, and ecosystem maturity. If accuracy is what drives your decision, switch to Cronometer. If chain restaurant logging or ecosystem integrations are what drive your decision, stay with MyFitnessPal. The honest answer is not “one app wins everything.”

Frequently Asked Questions
Is Cronometer actually more accurate than MyFitnessPal?
On the data-quality dimension, yes — Cronometer's verified-by-default database removes the per-entry crowdsourcing noise that drives error in search-based trackers using MyFitnessPal's user-submitted pool. MyFitnessPal users who turn on the verified-entry filter (Premium) close some of this gap. Whether the field-test MAPE difference is meaningful depends on your specific foods and how much you rely on long-tail entries. Our weighed-reference numbers publish with the first benchmark batch.
Is MyFitnessPal still useful if Cronometer is more accurate?
Yes. MyFitnessPal has roughly 11x the database entries, the best US chain restaurant coverage in the consumer category, and 15+ years of ecosystem maturity. For users who eat at chain restaurants frequently or have years of MFP history, the platform's practical advantages remain real.
Should I switch from MyFitnessPal to Cronometer?
Depends on your use case. If accuracy and micronutrient tracking matter, yes. If chain restaurant coverage matters or you have years of historical data inside MFP, the switch is less clear. Many serious users keep MFP for restaurant logging and use Cronometer for everything else.
Cronometer vs MyFitnessPal — which has a better free tier?
Cronometer's free tier is materially more useful. MFP's free tier paywalls the verified-entry filter, AI photo, recipe import, and advanced reports. Cronometer's free tier includes full calorie/macro logging, barcode, basic micros, and the diary.
Which app has better barcode scanning?
MyFitnessPal has the larger packaged-goods barcode catalog. Cronometer's barcode catalog is smaller but for verified entries the per-entry data quality is higher. For US grocery shopping, MFP finds more barcodes; for verified data on the barcodes it does have, Cronometer is more accurate.
Does Cronometer have the same crowdsourced noise problem as MyFitnessPal?
No — Cronometer's database is verified by default. User-submitted entries exist but are quarantined as a separate opt-in tier. MyFitnessPal's database is crowdsourced by default, with the verified filter as an opt-in tier. The defaults are reversed.
Which is better for tracking micronutrients?
Cronometer, decisively. MyFitnessPal tracks a handful of micros (sodium, potassium, sometimes fiber and a couple of vitamins). Cronometer tracks 80+ per food — every B-vitamin, every mineral, omega-3 / omega-6 ratio, amino acid profile.
