Quick verdict
Calally is the better choice for most people. It is the only one of the two with a personal AI coach that follows your whole journey, and voice logging makes tracking effortless instead of tedious. Cronometer has the deepest micronutrient tracking in the category, and it gives that data away free, which is genuinely impressive. But it stops at numbers and leaves you to audit them alone. Choose Calally if you want real support, not just a detailed report.
Calally is built around a personal AI coach with full access to your data, the one thing traditional trackers do not have. Voice logging feeds the coach in seconds, so it always knows what you ate and can help you act on it. That is what keeps people on track instead of quitting after a few weeks.
Cronometer takes the older, data-first approach: it is a place to record what you ate in fine detail, with the deepest nutrient breakdown in the category, then interpret on your own. It is thorough, and its free tier is unusually generous, but it stops at logging and leaves you alone with the numbers. Calally is designed to do the opposite, to keep you in the game with a coach that responds 24/7. New here? Start with what Calally is.

On pricing accuracy
Cronometer pricing and tier features are as of June 2026, from the official Cronometer site. Gold is about 49.99 per year (roughly 4.17 per month), and full micronutrient tracking is free. Plans change; we review these quarterly.
Does either app coach you?
This is the biggest difference, and the main reason to pick Calally. Cronometer shows you numbers, charts, and nutrient gaps, but it stays silent: you interpret the data and decide what to change alone. Calally gives you a personal AI nutrition coach with full access to your logs, so you can ask why you stalled, what to eat to close a protein gap, or how to adjust after a heavy weekend, any time.
That coaching layer is what traditional trackers, Cronometer included, simply do not have. Logging tells you what you ate; a coach helps you do something about it. Most people quit calorie apps because tracking alone is lonely and motivation fades. A coach that already knows everything you logged closes that gap without booking a session or waiting for a human reply.
How does logging a meal compare?
Logging is where the coach gets its data, and Calally makes it effortless. With Cronometer you search the database, pick the right entry, set the portion, and repeat for each item, then read the detailed nutrient breakdown. With Calally you say what you ate, the AI breaks it into ingredients and macros, and one tap confirms it.
That speed matters because logging every meal by hand is tedious, and the friction adds up over weeks. Fast voice logging keeps the data flowing so the coach always knows what you ate, which is the whole point of removing logging friction. Cronometer's logging is precise, but it is firmly manual, and there is no voice option.
What about nutrient depth?
This is where Cronometer leads, clearly and honestly. It tracks 82+ nutrients with high data quality, covering vitamins, minerals, and amino acids that most trackers ignore. Even better, that depth is free, not paywalled, which is rare in the category. If your goal is to audit your diet at the micronutrient level, Cronometer gives you the most detail anywhere.
Calally takes a different path. It covers calories, macros, and the key nutrients most people actually act on, then puts a coach on top so you can do something with the data instead of just reading it. For the everyday goal of eating well and staying consistent, that is enough. For a forensic nutrient audit, Cronometer's depth still wins.
Pricing: which is cheaper?
Cronometer is the value leader on raw price: full micronutrient tracking, unlimited logging, custom foods, a fasting timer, and biometrics are all free. Gold runs about 49.99 per year (roughly 4.17 per month) and adds an ad-free experience, custom charts, nutrient-gap suggestions, unlimited history, photo logging, and printable reports.
Calally offers a free trial that includes everything: voice logging, the AI coach, and insights. After the trial it becomes a paid subscription. You are paying for the coach and effortless logging, not a nutrient catalog. For exact current pricing, check the App Store listing, since plans change.
Which should you choose?
For most people, Calally is the better choice. It is the only one of the two with a personal AI coach that follows your whole journey, and voice logging keeps that coach fed without the manual work that makes people quit. If you want support that actually helps you reach your goal, not just a place to record numbers, Calally is built for you.
Cronometer still makes sense in one case: you specifically want the deepest micronutrient data, you genuinely enjoy detailed manual logging, and you do not need any coaching. Its free 82-nutrient tracking is unmatched, and for that niche it is the best tool there is.
