A free alternative to Cal AI? Mostly, there isn't one
We read the App Store listing of every major photo food app looking for one thing: can you photograph a meal and get the numbers without paying? For calories, the answer is almost always no. Photo scanning is the feature these apps charge for.
That still leaves real choices: apps that tested more accurately than Cal AI, apps with cheaper plans, free manual logging, and a free photo scanner that measures something other than calories. Every claim below is quoted from the listing so you can check it.
US App Store listings checked October 7, 2026. Prices change; the listing is the source of truth.
Is photo scanning free? The 7 apps checked
"NIH miss" is the average calorie underestimate per meal in a 2026 NIH test of 102 weighed meals (only four apps were tested).
| App | Photo scan | Gives you | NIH miss | App Store |
|---|---|---|---|---|
| Cal AI | Paid | Calories and macros | -345 kcal | 4.8 (369K) |
| Appediet | Unclear | Calories and macros | -252 kcal | 4.8 (47K) |
| MyFitnessPal | Paid | Calories and macros (Meal Scan) | -327 kcal | 4.7 (2.4M) |
| Lose It! | Paid | Calories and macros | -333 kcal | 4.8 (780K) |
| SnapCalorie | Unclear | Calories, macros, 100+ nutrients, portion estimate | Not tested | 4.7 (6.7K) |
| Calorie Mama | Unclear | Calories, with you confirming the food | Not tested | 4.8 (4.5K) |
| Flammyours | Free | Inflammation score 1 to 10, not calories | Does not count calories | 4.3 (100+) |
"Unclear" means the listing sells a subscription but does not say whether photo scans are limited without it. Install it, scan three meals and see where the paywall lands before you pay.
What each one is good for
1. Calories and macros
Cal AI
The baseline. Fast, polished, and the largest miss of the four apps NIH tested.
Listing: "food scanning analysis results require a subscription."
2. Calories and macros
Appediet
The least inaccurate in the NIH test. Worth trying first if accuracy is why you are leaving Cal AI.
Listing offers a subscription for "unlimited access to all features", which implies limits on the free version.
3. Calories and macros (Meal Scan)
MyFitnessPal
Free tier is manual logging against the biggest food database. Photo scanning is not free.
Listing puts barcode scan, meal scan and voice logging under Premium.
4. Calories and macros
Lose It!
Free calorie budget and manual logging. Photos need Premium.
Listing puts Photo Meal Logging and the barcode scanner under Premium plan features.
5. Calories, macros, 100+ nutrients, portion estimate
SnapCalorie
Pitches portion measurement, the main weakness of photo counting. Unverified by the NIH study.
Listing describes photo and voice logging but does not say what is free.
6. Calories, with you confirming the food
Calorie Mama
Cheapest clearly priced annual plan of the group if you end up paying.
Premium is $9.99 a month or $29.99 a year per the listing; photo recognition is described as the core feature.
7. Inflammation score 1 to 10, not calories
Flammy(our app)
Our app. Free photo scanning, but it answers a different question: how inflammatory the meal is.
Scanner is free; optional premium is $34.99 a year.
Three ways to track for free
| Route | Effort | Accuracy | Best for |
|---|---|---|---|
| Manual logging (MyFitnessPal or Lose It! free tier) | High: search each food, enter portions | Good if you weigh food | Calorie targets for weight loss |
| Food scale + nutrition labels | High, no app needed | The best you can get at home | A two-week calibration of your eyeball |
| Photo scanning for food quality (Flammy) | Low: one photo | Does not depend on grams | Eating better without counting |
Photo calorie apps run low on average (the NIH test found about a third), so the paid feature is not as precise as it looks. If you pay for one, correct portions and add cooking oil by hand. Our guide to food scanner apps covers the barcode scanners too, and our Flame Diet app review prices out the most expensive anti-inflammatory app on the store.
Free photo scanning. A different question.
Flammy scores any meal from 1 to 10 for inflammation from one photo and names the ingredients behind the score. No subscription needed to scan.
Why photo scanning is always the paid feature
Searching a food database costs the developer almost nothing per search. Recognizing food in a photo means sending the image to an AI model, and that has a real cost every time you tap the shutter. That is why every app above keeps manual logging free and puts the camera behind the subscription, and why "free alternative to Cal AI" mostly turns up trials.
Before you start one, read the subscription terms in the listing. The same three lines appear in almost every one of them:
| Auto-renewal | The subscription renews unless auto-renew is turned off at least 24 hours before the period ends. |
| Where to cancel | In your Apple ID account settings (Settings, your name, Subscriptions), not inside the app. |
| Free trial | Any unused part of a trial is forfeited when you buy, and the trial converts to paid automatically. |
Set a calendar reminder for the day before a trial ends. If the app has not changed how you eat by then, it will not after you pay.
Which to pick
| You want Cal AI but more accurate | Appediet (smallest miss in the NIH test) |
| You want to pay as little as possible for photo calories | Calorie Mama ($29.99 a year per its listing) |
| You refuse to pay anything | MyFitnessPal or Lose It! free tier, manual logging |
| You already use MyFitnessPal or Lose It! | Their Premium, so your history stays in one app |
| You care what is in the food, not the calories | Flammy, free |
Cal AI alternatives: common questions
Is there a free alternative to Cal AI?
Not a fully free photo calorie counter among the big names. MyFitnessPal and Lose It! list photo logging as a Premium feature, Cal AI requires a subscription for scan results, and Appediet, SnapCalorie and Calorie Mama all sell subscriptions. The free route is manual logging in MyFitnessPal or Lose It!. If you want free photo scanning for food quality rather than calories, Flammy's scanner is free.
Is Cal AI free?
You can download it and set up a plan, but its App Store listing states that food scanning analysis results require a subscription.
What is the most accurate alternative to Cal AI?
Of the four apps NIH researchers tested on 102 weighed meals, Appediet had the smallest average calorie miss (252 kcal per meal) and Cal AI the largest (345). All four underestimated. SnapCalorie and Calorie Mama were not part of that test.
Is Cal AI worth it?
If photo logging is the only way you will log at all, yes, as long as you treat the numbers as running low. If you need accurate calories, manual logging with a food scale beats every photo app tested.
Is Cal AI legit?
It is a real, very popular app: 4.8 stars from more than 368,000 ratings on the US App Store, published by Viral Development LLC since April 2024. Legit is not the same as accurate; see our Cal AI accuracy breakdown.
Is there a free app that scans food for inflammation?
Flammy scans a photo of any food or meal and returns a 1 to 10 inflammation score with the ingredients behind it, free. It does not count calories.
