What happened to Cal AI?
Cal AI was one of the most popular AI calorie trackers on the App Store, crossing 15 million downloads and generating over $30 million in revenue. In March 2026, MyFitnessPal acquired Cal AI in a reported nine-figure deal. Weeks later, in April 2026, Apple removed the app from the App Store entirely.
Why Apple removed Cal AI
A viral post on X exposed Cal AI's use of Stripe payments through Superwall — a payment sheet designed to look like a native iOS prompt but actually bypassing Apple's in-app purchase system. This let Cal AI pay Stripe's 2.9% fee instead of Apple's 15–30% commission. More importantly, it made subscriptions harder for users to cancel because they didn't appear in Apple's subscription management. Apple pulled the app for violating App Store payment guidelines.
The result: millions of users who relied on Cal AI for daily calorie tracking suddenly lost access to the app. Copycat apps flooded the App Store search results, many of low quality. If you're one of those users looking for a real alternative, here's how 0xCal compares.

What 0xCal does that Cal AI did
The core promise of Cal AI was simple: take a photo of your food and get calories. 0xCal delivers the same thing — and goes further with text-based logging that Cal AI lacked.
Photo logging
Both apps let you snap a photo and get instant calorie and macro estimates. 0xCal uses the latest AI models to analyze your meal photo — identifying individual foods, estimating portions, and returning a full breakdown of calories, protein, carbs, and fat within seconds. If you liked Cal AI's photo scanning, 0xCal feels instantly familiar.
Natural language input
This is where 0xCal pulls ahead. Cal AI was primarily photo-based, with voice input as a secondary option. 0xCal lets you type what you ate in plain English — "chicken stir fry with rice and broccoli" or "a large latte and a blueberry muffin" — and get accurate results. This is faster than finding your camera when you're at your desk, and far more flexible for describing homemade meals where the final dish might not photograph well.
Barcode scanning
Both apps include barcode scanning for packaged products. Point your camera at a barcode and get instant nutrition data from the product label.
What 0xCal does better than Cal AI
Transparent billing through Apple
Cal AI's biggest controversy was its payment system. By routing payments through Stripe instead of Apple's in-app purchase system, Cal AI subscriptions didn't show up in your iPhone's subscription settings. Users who wanted to cancel had to dig through emails or contact support directly. 0xCal uses Apple's standard in-app purchase system — your subscription shows up in Settings, you can cancel with two taps, and Apple handles refund disputes.
Better handling of homemade meals
Cal AI worked best when you could photograph a clearly visible plate of food. But many homemade meals — stews, casseroles, mixed bowls, wrapped items — don't photograph well. 0xCal's text input solves this: type "beef stew with potatoes, carrots, and bread" and get a full macro breakdown without needing a camera-friendly plate.
Typo and misspelling tolerance
Type "mackdonal chiken nugits" or "starbcks vanila frapachino" into 0xCal and the AI understands exactly what you mean. This matters more than you'd think when you're logging meals quickly throughout the day. We test typo handling in our weekly benchmarks against USDA reference data.
Stronger privacy
Cal AI required an account and stored user data on external servers. 0xCal takes a different approach: no account required, no meal photos stored on servers, no advertising SDKs, and all Apple Health data stays on your device. There's no social layer, no profile, and no data monetization. See the full privacy policy.
No risk of removal
0xCal follows Apple's guidelines exactly — standard in-app purchases, standard subscription management, no third-party payment bypasses. Your calorie tracking app won't disappear overnight because of payment policy violations.
Accuracy
Cal AI claimed 99.8% accuracy in meal identification. In practice, user reports told a different story — accuracy varied significantly with lighting, plate presentation, and mixed dishes. Many users reported issues with portion size estimation and complex meals.
0xCal takes a different approach to accuracy. We run a public weekly benchmark testing 72 foods against USDA reference data from FoodData Central. This includes everyday staples, complex homemade meals, restaurant dishes, international cuisine, and intentionally misspelled inputs. The results and methodology are fully transparent — you can see exactly how 0xCal performs on every tested food.
Transparent benchmarks vs marketing claims
Cal AI's "99.8% accuracy" was a marketing number with no published methodology or test data. 0xCal publishes its complete benchmark results, including failures and edge cases, every week. When it comes to calorie tracking accuracy, verifiable data beats marketing claims.
Pricing
Cal AI's pricing ranged from per-scan microtransactions to annual plans up to $59.99, processed through Stripe rather than Apple. This meant your Cal AI subscription wouldn't appear in your iPhone's Manage Subscriptions screen, making cancellation confusing. 0xCal offers a simple free trial, then one subscription plan through Apple's standard system — visible in Settings, cancellable in two taps.
What Cal AI did well
Cal AI deserves credit for popularizing AI-powered food logging:
- Photo-first UX — Cal AI made "snap a photo to log food" mainstream. The concept resonated with millions of users tired of manual database searching.
- Large user base — with 15M+ downloads, Cal AI proved the market demand for AI calorie tracking.
- Cross-platform — Cal AI was available on both iPhone and Android. 0xCal is currently iOS only.
- Progress tracking — Cal AI included streaks, progress charts (7-day, 30-day, 90-day), and daily calorie rings that many users found motivating.
- Third-party integrations — Cal AI connected with MyFitnessPal, Fitbit, Google Fit, and other fitness apps.
Where 0xCal wins as a Cal AI replacement
- Actually available — 0xCal is on the App Store right now. Cal AI is not.
- Text + photo + barcode — three ways to log meals, not just photos. Type what you ate when your camera isn't convenient.
- Transparent billing — Apple's standard in-app purchase. Shows up in Settings. Cancel anytime.
- Homemade meal support — describe complex dishes in plain English without needing a photogenic plate.
- Typo tolerance — AI understands misspelled food names and brands.
- No account required — start logging immediately without creating a profile or entering personal information.
- Privacy-first — no stored meal photos on servers, no ad tracking, no social features.
- Clean native iOS design — minimal, dark interface focused entirely on fast food logging.
- Published accuracy benchmarks — 72-food weekly tests against USDA data, fully transparent.
- No risk of App Store removal — follows Apple's payment guidelines exactly.
Bottom line
Cal AI proved that millions of people want to track calories with AI instead of manually searching food databases. But the app is gone — removed from the App Store for payment policy violations after its acquisition by MyFitnessPal.
0xCal picks up where Cal AI left off. Same AI-powered photo logging, plus natural language input that Cal AI never had. Transparent Apple billing instead of Stripe payment bypasses. Published accuracy benchmarks instead of marketing claims. No account required, no ads, and your data stays on your device.
If you used Cal AI, 0xCal is the most direct replacement available on the App Store today.
