Bento Bunny is an AI-powered calorie tracker. Type what you eat of your food and get instant calorie counts and macro breakdowns — no manual logging, no barcode scanning required.

How does the AI food recognition work?

Take a photo of your meal and Bento Bunny's AI identifies the food, estimates portion sizes, and calculates calories, protein, carbs, and fat automatically. It works with home-cooked meals, restaurant dishes, and packaged foods.

Bento Bunny offers a free tier to get started with basic photo tracking. Premium features like detailed macro breakdowns, meal history analytics, and custom nutrition goals are available with a subscription.

What platforms does Bento Bunny support?

Bento Bunny is available on iOS and Android. Your food log and nutrition data sync across all your devices.

How accurate is the AI calorie tracking?

Bento Bunny's AI is trained on thousands of foods and dishes. You can also adjust portions and ingredients after scanning for even more accurate tracking. It gets smarter the more you use it.

How is Bento Bunny different from MyFitnessPal or Lose It?

Unlike traditional calorie trackers that require manual search and barcode scanning, Bento Bunny uses AI photo recognition to log meals instantly. No typing, no searching through databases — just snap and track.

What Makes a Good AI Calorie Tracker?

AI calorie trackers replace database search with a camera: photograph your meal and the AI estimates calories and macros in seconds. The best ones get four things right — recognition accuracy, logging speed, fair pricing, and privacy (whether your photos stay on your device or go to the cloud). Here are the best AI calorie trackers in 2026, including the best free option.

What to Look For

Accuracy on real, mixed meals — not just single foods.
Input flexibility — photo, barcode, and text logging.
Price — is there a genuine free tier, or just a trial?
Privacy — on-device processing vs cloud upload of your meal photos.

1. Bento Bunny — Best Free AI Calorie Tracker

Bento Bunny logs a full meal in about five seconds from a photo, scans barcodes, and lets you type what you ate. Two things set it apart: it's free during its iOS beta (no subscription for AI logging or barcode scanning), and on iOS 26+ it processes meal photos on-device using Apple's Foundation Models, so your photos never leave your phone. It also imports MyFitnessPal and Cronometer exports, so switching keeps your history.

Best for: Anyone who wants Cal AI-style speed without the subscription or the cloud.

2. Cal AI — Most Popular

The best-known AI calorie tracker. Fast, polished, with photo, text, and barcode logging. The catches are price (no real free tier — around $9.99/month after a trial) and cloud-based photo processing. Accurate for clear foods, more approximate for mixed dishes. See our full Is Cal AI worth it? review and the Bento Bunny vs Cal AI comparison.

Best for: People who want the most established option and don't mind paying.

3. SnapCalorie

An AI photo tracker built by researchers with a strong computer-vision pedigree. Good accuracy on photo estimation; smaller ecosystem than Cal AI and a subscription model.

Best for: Photo-logging purists who want a research-led estimator.

4. MyFitnessPal (with Meal Scan)

Not AI-first, but its Premium+ tier adds a Meal Scan photo feature on top of the largest food database in the category. Logging is still mostly database-driven, and the photo feature sits behind the top paywall.

Best for: People tied to MyFitnessPal's database who want occasional photo logging.

5. Lose It! (with Snap It)

A friendly database tracker with Snap It photo logging. Snap It leans on database matching rather than full-plate estimation, so it's less reliable than dedicated AI apps, but the free tier is usable.

Best for: Casual trackers who want a cheap app with occasional photo logging.

The Best Free AI Calorie Tracker

Most AI trackers charge a subscription. If "free AI calorie tracker" is what you're searching for, Bento Bunny is the standout — full AI photo logging, barcode scanning, and text logging, free during the iOS beta, with your photos kept on-device. It's also the best Cal AI alternative if the price or cloud processing is what's holding you back.

How to Choose

Want the most established paid option? Cal AI. Tied to a huge database? MyFitnessPal. Want AI speed for free with on-device privacy? Bento Bunny. For most people deciding between paying for Cal AI or trying a free alternative first, the smart move is to test Bento Bunny — it costs nothing during the beta.

Frequently Asked Questions

What is the best AI calorie tracker?

Cal AI is the most popular paid AI calorie tracker, while Bento Bunny is the best free one — it offers AI photo logging, barcode scanning, and text logging free during its iOS beta, and processes meal photos on-device on iOS 26+ so they never leave your phone. The best choice depends on whether you want the most established option (Cal AI) or free, private AI logging (Bento Bunny).

What is the best free AI calorie tracker?

Bento Bunny is the best free AI calorie tracker in 2026. Unlike Cal AI and SnapCalorie, which require subscriptions after a trial, Bento Bunny offers full AI photo logging, barcode scanning, and text logging free during its iOS beta, with on-device photo processing on iOS 26+.

Is there a free alternative to Cal AI?

Yes — Bento Bunny is the closest free alternative to Cal AI. It offers the same photo, barcode, and text logging workflow, is free during its iOS beta, and keeps your meal photos on-device on iOS 26+, which Cal AI's cloud processing does not.

How accurate are AI calorie trackers?

AI calorie trackers are quite accurate for clearly visible, recognisable foods and less accurate for mixed dishes, sauces, and hidden fats. They produce estimates, not exact measurements — good enough for consistent calorie tracking but not a substitute for a food scale when precision is critical.

Which AI calorie tracker is most private?

Bento Bunny is the most private — on iOS 26+ it processes meal photos on-device using Apple's Foundation Models, so your photos never leave your phone. Most other AI trackers, including Cal AI, upload photos to the cloud for analysis.
