Cal AI is a calorie tracker built around one idea. You take a picture of your meal, and it works out what’s on the plate. We used it on an iPhone in October 2026, and the screenshots here come from our account. MyFitnessPal bought Cal AI in a deal that closed in December 2025 and runs it as a separate app. If you’re choosing between the two, see Cal AI vs MyFitnessPal.
Logging a meal from a photo
Photo logging is the reason Cal AI exists. The camera opens on Scan Food, with Barcode and Food label beside it, and a button for a photo you already took. Its home page says your phone’s depth sensor “calculates food volume” before its AI breaks the meal down.
We photographed a cheese biscuit. Cal AI called it a Cheddar Herb Scone at 220 calories, with 6 grams of protein, 22 of carbs and 12 of fat, and an Ingredients section you can add to. Under the result sit two buttons, Fix Issue and Done.
The scan doesn’t wait for you. Cal AI estimates in the background, with a note that it will notify you when it’s done, and our biscuit was on the day’s total within about half a minute of the photo, before we’d opened the result. MyFitnessPal’s Meal Scan works the other way round, with a list of foods to choose from before anything is logged.
Fix Issue is how you correct it afterwards. It asks you to “Describe what needs to be fixed”. We told it what the food was, and it re-analysed the photo. It came back renamed Cheese Biscuit, with the same 220 calories and the same protein, carbs and fat.
Voice, search and barcodes
The + button opens four choices, Scan food, Food Database, Saved foods and Log exercise. Log Food lets you type what you ate, pick from your own foods and meals, add one by hand, or tap Voice Log and say it. We said “bagel”. Cal AI wrote it down, and 20 seconds later a Bagel was on the day at 270 calories, with no photo.
Search and barcodes draw on a food database. Since the sale, Cal AI’s search uses MyFitnessPal’s, TechCrunch reports. That database is a combination of foods added by MyFitnessPal and foods added by its users, so the same food can appear more than once with different values.
How accurate it is
Cal AI’s FAQ says it is “about 80% accurate”, and doesn’t say what that measures. When MyFitnessPal bought it, TechCrunch put the trade plainly—“Cal AI is for those preferring speed over accuracy. MFP is for those wanting the reverse.”
One outside test has looked at Cal AI. Researchers at the NIH took photos of 102 meals from a diet study, where every ingredient is weighed to a tenth of a gram, and ran them through Cal AI, MyFitnessPal, Lose It! and Appediet. All four apps undercounted by about 250 to 345 calories a meal on average, and by about 30 grams of fat. The release gives no result for each app, and the findings are preliminary until they’re peer reviewed.
Targets
Cal AI builds your plan from a quiz when you sign up—“Answer lifestyle questions to build your plan”, in its words. From then on, the targets are yours. Edit nutrition goals takes a number for calories, protein, carbs and fat, with fiber, sugar and sodium under “View micronutrients”. Auto Generate Goals asks the quiz again, about your workouts, height and weight, goal and pace, and offers a new daily recommendation that “You can edit this anytime”. We found no setting that changes the targets on their own.
Two switches in Preferences add to the day’s goal. “Add burned calories” puts workout calories back, and “Rollover calories” carries over “up to 200 left over calories from yesterday”. Those were the +426 and +200 under “Calories left” on October 5. A third, “Auto adjust macros”, rescales a food’s other numbers when you edit one.
Is Cal AI free? Price and the trial
Cal AI tests its prices, and they change often. Superwall, the company behind Cal AI’s paywall, says Cal AI tests weekly, monthly, quarterly, annual and lifetime plans, along with their prices and trials. Its store listings show purchases from $2.99 to $29.99 on the App Store, and $9.99 to $59.99 on Google Play, without saying how long each one lasts. The App Store’s list changed twice between October 5 and October 16.
On October 16, our account was offered $29.99 a year, or $9.99 a month, with “3 days free” on the yearly plan. The paywall lays out the trial. Today everything unlocks, in two days it reminds you if you’ve allowed notifications, and in three days billing starts. Someone else may see different prices.
There’s no free plan. Its App Store listing says “food scanning analysis results require a subscription”, and its FAQ says the button to log food “opens the paywall screen”. Profile also offers an upgrade to a family plan, and a reward for each friend you refer.
Friends and streaks
Cal AI counts a daily streak, the flame at the top of the home screen. Ours went from 0 to 1 when the biscuit was logged. It sells a Streak Restore if you break one. Groups lets friends see each other’s meals, with their calories and macros, and react or comment.
Taking your data with you
Cal AI exports a PDF summary report of your log, from Profile. Asked whether it can import your MyFitnessPal history, its FAQ says “Not yet”. It runs on iPhone, Apple Watch and Android, with no web app.
Where Fit Shapes fits
Cal AI gives you a short 3-day trial to find out whether its estimates work for you, and its prices keep changing. Its export is a PDF report, which is hard to take anywhere else.
Fit Shapes is built for speed and ease of use. It logs a meal from a photo instantly. Every subscription includes photo and voice logging, barcode scanning and Adaptive Targets. Each week, Fit Shapes proposes changes to your targets based on what you eat and weigh. It has no ads and does not sell your data. It also imports your data from Cal AI. So if you decide to switch, you can bring your history with you.
The catch is that Fit Shapes has no free plan. After the 14-day free trial, you pay for a subscription.
Questions
Is Cal AI free?
No. Cal AI is free to download, but its photo results need a subscription, and logging food opens its paywall. It has a short 3-day trial.
How much does Cal AI cost?
Cal AI doesn’t publish a price list, and it keeps testing its prices. Its store listings show purchases from $2.99 to $29.99 on the App Store, and $9.99 to $59.99 on Google Play, without saying how long each one lasts. In October 2026, our account was offered $29.99 a year, or $9.99 a month.
Is Cal AI accurate?
Cal AI says it is “about 80% accurate”, without saying what that measures. In a preliminary NIH test of 102 weighed meals, Cal AI, MyFitnessPal, Lose It! and Appediet all undercounted calories, by about 250 to 345 a meal on average. The results weren’t given for each app.
Is Cal AI good?
It’s good at one thing, logging a meal from a photo with almost no effort. Our biscuit was on the day’s total within half a minute, and a spoken “bagel” within 20 seconds. Its own accuracy figure is about 80%, it has no free plan, and its trial is short. If speed matters more to you than precision, it’s a good fit.
Does Cal AI work?
It does what it says. You photograph a meal, and Cal AI logs an estimate of its calories and macros, about half a minute later for our biscuit. If it’s wrong, you fix it afterwards. How close the estimate comes depends on the meal. Cal AI’s own figure is about 80%, and in the NIH test the photo apps missed most in fat.
Is Cal AI worth it?
It depends on how you log. If photos fit the way you eat, Cal AI includes photo logging and barcode scanning in its subscription. Its prices change often, so check what you’ll pay before the short trial ends.
Does Cal AI have voice logging?
Yes. Tap Voice Log on the Log Food screen and say what you ate. We said “bagel”, and Cal AI logged a Bagel at 270 calories. You can type a description instead.
Was Cal AI removed from the App Store?
Briefly, in April 2026. Apple said the removal was “due to multiple violations of its rules”, including bypassing its in-app purchase flow. After a period of unavailability, the app returned to the App Store.
Does Cal AI work on Android?
Yes. Cal AI runs on Android 10 or later, as well as iPhone and Apple Watch. A subscription bought on one platform doesn’t carry over to the other.
