Quick verdict
Pick MyFitnessPal if you want the largest food database for fast search-and-log. Pick Cronometer if micronutrient depth and data quality matter most, and you want that depth free. But for most people, Calally is the better choice. It adds the two things both apps lack: a personal AI coach with full access to your data, and voice logging that removes the friction that makes people quit in the first place.
The real MyFitnessPal vs Cronometer decision comes down to a clean tradeoff. MyFitnessPal gives you the biggest food database built over 10+ years, with millions of entries, so almost anything you eat is already in there. Cronometer goes the other direction: fewer shortcuts, but deeper and cleaner data, including 82+ micronutrients tracked free. One optimizes for breadth, the other for accuracy. That's the honest summary, and for a lot of people either would be a reasonable pick. To understand where each fits, it helps to know what Calally is first.
There's a catch both apps share, though. Both are manual loggers with no coach. You do the searching, the logging, and the interpreting yourself. Calally is the superior third way because it flips that: a 24/7 AI coach reads your actual eating data and guides you, while voice logging feeds it in seconds instead of taps. The database-vs-micronutrients debate matters less once an assistant is doing the thinking with you.

Does either app coach you?
Neither MyFitnessPal nor Cronometer coaches you. This is the gap that defines both. They are excellent databases and trackers, but they stop at the numbers. You log a day, you see totals and charts, and then you're on your own to decide what to do next. There's no one reading your week and saying "you're short on protein again, here's a fix." That interpretation is left entirely to you.
Calally is built around exactly that missing piece. The personal AI coach has full access to your data, 24/7, so it answers real questions: what to eat tonight, why your energy dips, how to hit a goal without guesswork. Voice logging exists to feed the coach fast, so it always has current data to work from. If you've ever wondered what that looks like in practice, see AI nutrition coach.
MyFitnessPal vs Cronometer: database or micronutrients?
This is the honest head-to-head, and it has a clear split. MyFitnessPal wins on database breadth. A decade-plus of entries means restaurant meals, packaged foods, and obscure items are usually already there, so logging is fast once you find the match. The tradeoff is variable quality, since many entries are user-submitted.
Cronometer wins on micronutrient depth and data quality. It tracks 82+ micronutrients against tightly curated sources, and that depth isn't paywalled. If you care about iron, magnesium, or vitamin gaps rather than just calories and protein, Cronometer is the better tool. Both apps are manual, though, so the depth-vs-breadth question is really about which kind of detail you want to enter by hand.
How does logging compare?
Both MyFitnessPal and Cronometer use manual search logging: type the food, scan a code where available, pick the match, set the portion. It works, but it's the same step that quietly kills consistency. Search fatigue is the single biggest reason people abandon tracking after a few weeks, which we cover in removing logging friction.
Calally takes a different route. You describe the meal out loud, the AI extracts the ingredients and macros, and you confirm with one tap. No scrolling a database, no hunting for the right entry. Instead of a giant searchable index, Calally estimates from your description, which is faster for everyday meals and keeps your coach's data fresh.
Which should you choose?
Choose MyFitnessPal if your top priority is the biggest possible food database and fast search-and-log on common items. Choose Cronometer if micronutrient depth and clean data matter most, and you want serious nutrient tracking for free. Both are genuinely good at what they do, and either can work if manual logging doesn't bother you.
But for most people, Calally is the better choice. It's the only one of the three with a personal AI coach that reads your data 24/7, and voice logging removes the friction that makes people quit. That combination fixes the two reasons trackers fail. For the direct matchups, see Calally vs MyFitnessPal and Calally vs Cronometer, or browse more MyFitnessPal alternatives.
