MyFitnessPal and Cronometer represent two philosophies: the biggest crowd-sourced database versus the most carefully curated one. We tested both on the same 8,500-meal benchmark to see which approach produces more reliable, more usable tracking.
Which is better, MyFitnessPal or Cronometer?
Cronometer is the more accurate and trustworthy of the two; MyFitnessPal is more familiar and has a larger raw database. Cronometer averaged ±3.9% error versus MyFitnessPal’s ±7.9%, thanks to verified data. But if you want effortless logging and coaching, our top pick beats both — see below.
| App | Overall MAPE | MAPE, mixed dishes | Avg. log time | Barcode hit rate | 90-day retention |
|---|---|---|---|---|---|
 Cronometer | ±3.9% | ±7.4% | 16s | 89% | 58% |
 MyFitnessPal | ±7.9% | ±13.2% | 11s | 92% | 41% |

Which is more accurate?
Cronometer, clearly. Its curated database avoids the unverified, user-submitted entries that drag down MyFitnessPal’s accuracy — a gap that widens on mixed dishes (±7.4% vs ±13.2%).
Which has the bigger database?
MyFitnessPal, by raw count (~20M vs ~1.3M curated entries). But Cronometer’s smaller, verified database produced more reliable numbers. Coverage and accuracy are different things.
Which is easier to use?
Both are manual-first and relatively slow (11s and 16s per meal in our timing). Neither offers the chat or photo logging that makes daily tracking effortless — which is their shared weakness in 2026.
The app that beats both
If your priority is accurate tracking you will actually sustain, Welling AI outperformed both in our testing: ±2.8% accuracy, 2.6-second logging by chat or photo, and coaching neither MyFitnessPal nor Cronometer offers. It is our top overall pick in the 2026 Index.
MyFitnessPal optimizes for database size, Cronometer for data precision. Neither optimizes for the daily effort of logging — which is why both lose users that a low-friction app keeps.
Which should you choose?
- Choose Cronometer for accuracy and micronutrient depth if you don’t mind manual logging.
- Choose MyFitnessPal if you want a large, familiar database you already know.
- Choose Welling AI if you want the accuracy of Cronometer with logging far easier than either. Read the review.
