Free AI Calorie Counter Apps: Photo Tracking Without a Trial
Almost every AI calorie counter that logs meals from a photo is a subscription with a short trial attached — Cal AI, CalorieCue and most of the category charge once the trial ends. PlateLens is the exception: its free plan includes photo, voice and text logging plus the AI coach, with daily allowances that reset rather than an expiry date. If you want photo logging and refuse to subscribe, that is the practical shortlist.
AI photo recognition costs the developer money on every single scan, which is why the category defaults to subscriptions. A permanent free plan in this space always comes with a daily allowance — the honest question is whether it resets or runs out for good.
Why free AI photo logging is rare
Every photo you send for analysis costs the app real money in model inference. A database lookup costs effectively nothing, which is why FatSecret and Cronometer can afford to be free forever and photo-first apps generally cannot.
That leaves three business models, and they are easy to tell apart once you know what to look for:
- Trial then charge. Full access for a few days, then a subscription. Most of the category.
- Free plan with daily allowances. Everything is unlocked, but photo scans have a per-day cap that resets each day. Nothing expires.
- Free tier without AI. The free plan exists, but photo recognition sits behind the paywall — MyFitnessPal and Lose It! both work this way.
Only the second one lets you photograph your meals indefinitely without paying.
The options
PlateLens — photo, voice and text on a plan that doesn't expire
PlateLens puts photo scanning, voice logging, text logging, barcode scanning and the AI coach on the free plan. Photo scans and coach messages carry a daily allowance that resets; nothing counts down toward a charge and no card is needed to start. When the estimate is wrong you fix it by saying so — "that was two eggs, not one" — which is faster than searching a database for the correct entry.
- Photo, voice and text meal logging
- Barcode scanning
- The AI coach
- Calories and macros in grams
- Apple Health and Health Connect sync
- Daily allowances that reset, with no expiry date
- Premium at $9.99/month or $34.99/year lifts the daily allowances
- Free plan never expires, no card required
- AI coach included rather than paywalled
- Correct meals in natural language
- Works on phone, web and Apple Watch
- Give it the weights and it uses them instead of estimating
- 82+ micronutrients tracked from USDA FoodData Central
- Daily allowance on photo scans and coach messages
- No recipe builder
Best for: people who want photo logging permanently and won't subscribe.
Cal AI — photo-first, subscription-based
Cal AI is the best-known photo tracker and its recognition is strong on common foods. Access is trial-based: you get full features for a short period and then the subscription starts. There is no permanent free plan with photo logging.
- A short trial with full features
- Everything, once the trial ends: photo logging, macros and barcode scanning all require the subscription
- Strong recognition on common dishes
- Clean verification flow before saving
- Large user base
- Photo logging is not free after the trial
- Card usually required up front
- No AI coach on par with a full assistant
Best for: people happy to pay for photo logging.
Head to head: Cal AI accuracy vs PlateLens.
SnapCalorie, CalorieCue and the rest
The remainder of the category follows the same shape: a trial, then a subscription. CalorieCue is explicit that it is a trial rather than a free app, which is more transparent than most. SnapCalorie markets a free tier; check the current store listing for what the free plan covers, because these boundaries move.
Best for: comparison shopping — install two, use the trial, keep the one whose corrections feel least annoying.
Free alternatives without AI
If photo logging turns out not to matter to you, the fully free options are better than any limited AI plan. FatSecret has no subscription at all and keeps barcode scanning and gram-level macros free. Cronometer's free tier draws on verified USDA data and is the most accurate free option in the category. Both require manual logging, which is the trade.

How accurate is photo logging, really
It depends on how much you tell the app. A photo alone cannot see the oil in the pan or the butter under the sauce, and portion estimation from a single angle carries real variance — that is true of every photo tracker. But the estimate is not the only input you can give. PlateLens lets you add the weights and the missing ingredients in plain language, and when you do it uses those numbers rather than guessing at them, which puts it on the same footing as manual entry without the database search.
What photo logging buys you is speed, and speed is what decides whether you are still logging in six weeks. If you have abandoned manual tracking before, the accuracy gap matters far less than the fact that you actually keep doing it. Review the estimate, correct what looks wrong, move on.
Before you pick an app, work out the number you are tracking against: our calorie calculator gives you a daily target from your own stats. And for the record, PlateLens Premium is $9.99 a month or $34.99 a year — the free plan above needs no card and has no end date.
Photo logging that doesn't expire
Snap a photo, describe the meal, or scan a barcode. The AI coach is included on the free plan.
Frequently Asked Questions
Is there a free AI calorie counter app?
Yes. PlateLens has a permanent free plan that includes AI photo logging, voice and text logging and the AI coach, with daily allowances that reset. Most other AI photo trackers, including Cal AI and CalorieCue, offer a short trial and then charge.
What is the best free app to scan food for calories?
PlateLens is the best free option for scanning food by photo, because its free plan never expires and includes the AI coach. If you mean barcode scanning rather than photo recognition, FatSecret and Cronometer both include it free with no subscription at all.
Is there a free Cal AI?
No. Cal AI is subscription-based with a short trial; photo logging is not available for free once the trial ends. PlateLens is the closest free equivalent, with photo logging on a plan that does not expire.
How accurate are AI calorie counters?
It depends on how much you tell the app. From a photo alone, an estimate cannot see cooking oil, butter or dressings, and portion size from one angle varies. But you are not limited to the photo: PlateLens lets you add the weights and any missing ingredients in plain language, and it then uses those numbers instead of estimating them. Reviewed and corrected, a photo log is as accurate as manual entry without the database search.
Why do most AI calorie apps charge a subscription?
Every photo analysis costs the developer money in model inference, unlike a database lookup which is effectively free. That running cost is why photo-first apps default to subscriptions and why free plans in this category come with daily allowances rather than unlimited scanning.
Do I need a credit card to try an AI calorie counter?
For most of them, yes, because they are trials. PlateLens does not ask for one: its free plan has daily allowances rather than an expiry date, so there is nothing to cancel.
Can AI recognise homemade food?
Reasonably well for recognisable dishes, poorly for blended or heavily mixed ones like soups, stews and smoothies, where the visual cues disappear. Describing what went in fixes it faster than photographing it again.
What happens when I run out of free scans for the day?
On PlateLens the allowance resets the next day and you can still log by typing or describing the meal in the meantime. On a trial-based app, running out means the trial ended and the subscription starts.
Does AI photo logging work for restaurant meals?
Yes, and it is where photo logging is most useful, because restaurants plate food consistently and you rarely know the recipe. Adding what you can see — the oil, the dressing, the side — improves the estimate noticeably.
Can I correct a wrong AI estimate?
In PlateLens you correct it by describing the correction in text or voice, and the app uses what you tell it instead of its own guess. Most photo trackers instead ask you to edit numbers by hand or search a database for a replacement entry.
Is a free AI calorie counter good enough for weight loss?
Yes, provided you keep logging. Consistency drives the result far more than per-meal precision, and photo logging exists to remove the friction that stops people from logging at all.
