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 is the default, not a paid add-on. FatSecret has a real strength: it is genuinely free, with a large verified database and no paywall on the basics. But it leaves you alone with the numbers and has no conversational coach. Choose CalAlly if you want support; choose FatSecret if you only want free manual tracking.
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.
FatSecret takes the classic approach, done well and for free. Since 2007 it has built a large verified food database, and it gives away the basics (diary, barcode scanner, macros, weight log, recipes, community) without a paywall. It is a generous free tracker, but it stops at logging and leaves you to interpret the numbers alone. CalAlly is designed to do the opposite, to keep you in the game with a coach that responds 24/7.

Does either app coach you?
This is the biggest difference, and the main reason to pick CalAlly. FatSecret shows you a diary, macros, and trends, but it stays silent: you interpret the data and decide what to change alone. It does not have a conversational coach on either tier. 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 hit your protein, or how to adjust after a heavy weekend, any time.
That coaching layer is what traditional trackers, FatSecret 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 FatSecret you search the database, pick the right entry from the verified catalog, set the portion, and repeat for each item. 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.
FatSecret does offer voice logging (Smart Assistant) and photo logging (Smart Food Scan), but both sit behind Premium. On CalAlly, voice is the default way you log, not an upsell.
What about the food database?
This is where FatSecret is genuinely strong. Its database holds more than 900,000 verified foods, built since 2007, so packaged brands and common items are usually already there. If you want to search and confirm an exact catalog entry, and you want that for free, FatSecret gives you a lot of coverage at no cost.
CalAlly takes a different path. Instead of searching a catalog, it estimates ingredients and portions from your description. That is faster for everyday meals and home cooking, and it removes the "which of these entries is right" problem. For barcode-level precision on packaged goods from a free app, FatSecret's verified catalog still has an edge.
Pricing: which is cheaper?
FatSecret is the cheaper option on paper. The core tracker is genuinely free, with ads, and includes the database, barcode scanner, diary, macros, weight log, and recipe builder. Premium (about 38.99 to 59.99 per year depending on region) removes ads and adds Smart Food Scan, Smart Assistant, dietitian meal plans, and a water tracker.
CalAlly offers a free trial that includes everything: voice logging, the AI coach, and insights. After the trial it becomes a paid subscription. 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 searching 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.
FatSecret still makes sense in one case: you want a genuinely free tracker with a large verified database, you are happy logging manually, and you do not need a coach. If a no-cost basic tracker is all you are after, FatSecret is one of the best.
