What to look for in a free calorie counter app

18 October 2026 · 2 min read

There are lots of free calorie and macro trackers. Rather than naming winners, here is what to look for.

The features that matter

• Fast logging. If it takes minutes per meal, you will quit. Look for barcode scanning, recents, favourites and saved meals.
• A large, honest food database, with the source shown and unknown values left blank rather than shown as zero.
• Your own targets. You should be able to set your own calories and protein, carbs and fat, not only accept a preset.
• A clear explanation of how targets are worked out, such as TDEE, and what it assumes.
• Sensible safety rules. No extreme calorie targets, and extra care for young people.
• Useful history that shows trends in weight and intake, not just a list.
• Works offline or on a poor signal, since you often log on the go.

Red flags

• Aggressive "lose 10 pounds in a week" messaging.
• Targets you cannot change.
• Logging features hidden behind a paywall.
• Lots of ads or pop-ups that interrupt you.
• Asking for far more personal data than it needs.
• No way to delete your account and data.

Privacy matters

A food and weight diary is personal. Check whether you can use the app without an account, where your data is stored, and whether you can delete it.

Try before you commit

Log a normal day in two or three apps and see which one you can actually stick to. The best tracker is the one you will really use.

A ten-minute test plan

Before settling on an app, try this:

1. Log your last meal with a barcode scan, and time yourself.
2. Log a home-cooked meal made of three or four ingredients.
3. Set your own protein target and see whether the app lets you keep it.
4. Look for how it handles an unknown value (blank or zero).
5. Find the delete-my-account option.
6. Try it with your phone in airplane mode.

Questions worth asking about any app

• Who pays for it? If it is free, how does it make money? Ads and selling data are very different from optional extras.
• Where does the food data come from, and can you correct it?
• What does it do with your weight and age? Is that stored on your device or on a server?
• Does it push you to eat very little? A good app should have sensible limits.

Keep it proportionate

You do not need every feature. Most people get the most value from fast logging, honest numbers and a clear daily total. Everything else is a bonus.

Foodie is free, has no ads, works as an installable app, and lets you use it without an account. Give it a go.
