Here's what changed, how the two apps actually differ now, what each one costs, and which one fits how you log." publishedAt: "2026-08-04" updatedAt: "2026-08-04" author: "Inlab Products" category: "App comparisons" tags: ["MyFitnessPal vs Cal AI", "Cal AI acquisition", "MyFitnessPal", "Cal AI", "AI calorie tracker"] keyTakeaways:

• "MyFitnessPal and Cal AI are owned by the same company. MyFitnessPal acquired Cal AI in a deal that closed in December 2025 and was announced on March 2, 2026. Terms were not disclosed."
• "The two apps still run separately. MyFitnessPal has said it has no plans to merge Cal AI into its main product or migrate users, and Cal AI's seven-person team was retained."
• "The practical difference is the logging model: Cal AI is photo-first and fast, MyFitnessPal is search-first with a 20.5M+ food database. Since the acquisition, Cal AI is backed by that same MyFitnessPal database."
• "In April 2026 Apple pulled Cal AI from the App Store over its billing design — specifically an in-app purchase bypass and misleading subscription pricing — then restored it after the developer made fixes."
• "Both apps put AI logging behind a paid subscription. If you want photo or voice logging in a free tier, neither app is the answer." faq:
• question: "Is Cal AI owned by MyFitnessPal?" answer: "Yes. MyFitnessPal acquired Cal AI in a deal that closed in December 2025 and was publicly announced on March 2, 2026. Financial terms were not disclosed. Cal AI's co-founders Zach Yadegari and Henry Langmack and the rest of its seven-person team joined MyFitnessPal, and Cal AI continues to operate as a standalone app rather than being folded into MyFitnessPal."
• question: "Why was Cal AI removed from the App Store?" answer: "Apple pulled Cal AI in April 2026 for violating App Store billing rules. Per Apple's account to TechCrunch, the app bypassed the required in-app purchase flow using a Stripe-based checkout, displayed weekly pricing more prominently than the amount actually billed, used a free-trial toggle that did not make automatic renewal clear, and re-prompted users who declined with a different subscription offer. Apple said the issue was the deceptive billing design rather than external payments themselves. Cal AI was restored after the developer made changes."
• question: "Should I switch from MyFitnessPal to Cal AI now that they're the same company?" answer: "Only if the logging model suits you better. They remain separate apps with separate subscriptions — being under one owner does not merge your data or your plan. Cal AI is faster if you log by photo; MyFitnessPal is better if you log branded packaged foods by search or barcode and want web access."
• question: "Does one subscription cover both MyFitnessPal and Cal AI?" answer: "No. As of August 2026 they are billed as separate products with separate subscriptions. Paying for MyFitnessPal Premium does not unlock Cal AI, and vice versa. Confirm current terms in each app's App Store listing before subscribing."
• question: "Is Cal AI more accurate than MyFitnessPal?" answer: "They fail in different ways. Cal AI estimates from a photo, which typically lands within 10–25% of a weighed reference and is worst on layered or mixed dishes. MyFitnessPal is only as accurate as the database entry you pick, so a barcode scan of a packaged food is very accurate while a crowdsourced homemade entry can be far off. Photo estimation is faster; barcode scanning is more precise."

For most of 2024 and 2025 these two apps were the clearest rivals in calorie tracking: the decade-old database incumbent versus the viral photo-first newcomer. That framing is out of date. They now have the same owner.

This comparison is written by the team behind Callie, a competing app. We've kept the head-to-head itself neutral and sourced, and flagged clearly where we talk about our own product.

TL;DR

MyFitnessPal owns Cal AI, but they are still two separate apps with separate subscriptions and different jobs. Use Cal AI if you want to log by photo in a few seconds and don't want to think about a database. Use MyFitnessPal if you log branded packaged foods, want the largest food database and a web interface, or need broad wearable integrations. Neither includes AI logging in its free tier.

What actually happened

The timeline that matters:

Cal AI was built by Zach Yadegari and Henry Langmack, who started it while still in high school. By the time of the acquisition it had passed 15 million downloads in under two years and roughly $30 million in annual revenue. Its entire seven-person team, including Yadegari as CEO, was retained.

The two things MyFitnessPal has publicly committed to are worth noting, because they answer the question most existing users have:

1. Cal AI keeps operating as a standalone app. There is no plan to merge it into the MyFitnessPal app or migrate users across.
2. Cal AI now runs on MyFitnessPal's nutrition database — 20 million+ foods, 68,500 brands, and 380+ restaurant chains.

That second point is the substantive product change. Cal AI's weakest link was always what happened after the vision model identified your food: it needed nutrition data to attach numbers to. It now draws on the largest database in the category.

The April 2026 App Store removal

Worth understanding if you're evaluating Cal AI, because it was about billing rather than the tracking itself.

Apple removed the app in April 2026 and told TechCrunch it had found several violations:

• The app bypassed Apple's required in-app purchase flow, using a Stripe-based checkout instead. External payments are permitted after the Epic ruling, but Cal AI is not a "reader app," so it was required to offer in-app purchase alongside.
• Weekly pricing was displayed more prominently than the amount actually charged.
• The free-trial toggle did not make automatic renewal clear.
• Users who declined were re-prompted with a second, different subscription offer.

Apple was explicit that the problem was the deceptive billing design, not the use of external payments. Cal AI was restored after the developer made fixes, and subsequently ranked #4 on the App Store's Health and Fitness chart. Neither MyFitnessPal nor Cal AI commented publicly.

Pricing

Both apps are free to download and both gate their AI logging behind a subscription. Exact tier mapping shifts with promotions and region, so the honest presentation is the range each App Store listing shows.

In-app purchases listed	$0.99 – $29.99	$9.99 – $79.99
Monthly options	Weekly and monthly tiers	$9.99 / $19.99
Annual options	See listing	$49.99 / $79.99
Tiers	Single subscription	Premium and Premium+
Ads in free tier	No	Yes
One subscription covers both apps

In May 2026 MyFitnessPal also moved three more features into Premium: scan-a-meal (photographing a whole plate), recipe URL import, and macro-by-meal goals. Single-item barcode scanning, manual entry, and the food database itself remain free.

Head-to-head on each dimension

Speed

Cal AI wins clearly, and it's the reason the app grew as fast as it did. Photograph the plate, get numbers. There's no search box, no scrolling past nine near-identical crowdsourced entries for "grilled chicken breast."

MyFitnessPal is faster than Cal AI for exactly one case: a packaged food with a barcode. Scanning is both quicker and more accurate than any photo estimate.

Accuracy

These fail differently, which is more useful to understand than a single ranking.

• Cal AI estimates portion and content from an image. Category-wide, photo estimation lands within roughly 10–25% of a weighed reference, and degrades on layered or mixed dishes — casseroles, curries, anything where the calories are hidden under the surface. Oils and sauces are the usual invisible cost.
• MyFitnessPal is exactly as accurate as the entry you select. A verified barcode scan is near-exact. A crowdsourced entry for someone else's homemade lasagna can be off by a wide margin, and the database's duplicate-entry problem means picking well is a learned skill.

Neither app is a measuring instrument. Both are useful for spotting trends across weeks.

Database

This used to be MyFitnessPal's decisive advantage over Cal AI. After the acquisition it's a shared asset — 20 million+ foods, 68,500 brands, 380+ restaurant chains, now behind both apps. If database coverage was your reason to prefer MyFitnessPal over Cal AI, that reason is substantially weaker in 2026 than it was in 2025.

Where you can log

MyFitnessPal has a web interface. Cal AI is mobile-only. If you like reviewing or bulk-editing a week of logs on a laptop, that's a real difference.

Integrations

MyFitnessPal has a decade of integration work behind it — Garmin, Withings, Strava, Apple Health, Google Fit and a long tail beyond. Cal AI's integration surface is much smaller. Check both against whatever wearable you actually own.

Ads

MyFitnessPal's free tier shows ads. Cal AI's does not.

What the acquisition means for you

Three honest implications.

One company now owns both the largest food database and the most-downloaded photo tracker. That's good for Cal AI users, who inherited real nutrition data. It also means less competitive pressure in a category where the main direction of travel has been features moving from free to paid.

Your data doesn't move, and neither does your subscription. Separate apps, separate billing. Nothing about the acquisition changes what you're paying for.

"Which of these two is independent?" is no longer a question with an answer. MyFitnessPal has been owned by the private equity firm Francisco Partners since 2020, and Cal AI is now inside that structure. If you were choosing between an incumbent and a scrappy startup, that choice no longer exists in this pairing.

Which should you use?

Choose Cal AI if you log mostly home-cooked or restaurant meals, you want the fastest possible photo flow, you're on iOS 18 or later, and you don't need web access or deep integrations.

Choose MyFitnessPal if you log mostly branded packaged foods, you want the free single-item barcode scanner, you want a web interface, or you depend on a specific third-party integration.

Choose neither if free-tier AI logging is your requirement. Both apps paywall it.

A third option

Since that last point is where we live, we'll be direct about it: Callie is our app, and its AI logging is in the free tier.

The relevant differences, stated plainly:

• Photo, voice, and text logging are all free, rather than photo-only or Premium-only.
• Review before logging. Callie shows the detected foods, portions, calories and macros on a review screen and lets you edit before anything is saved. Given that photo estimation is 10–25% off across the whole category, catching the error before it enters your data matters more than the model's raw accuracy. Cal AI's flow is more automatic.
• A localized UI in English, French, Spanish, German and Arabic, with an AI coach that chats in any language. Both apps here are functionally English-first.
• Habit features neither has: a GitHub-style streak dashboard, scheduled cheat days that preserve your streak, and a daily diet plan matched to your BMI.

Where we don't win: MyFitnessPal's database is larger than ours, it has a web app and we don't, and its integration list is longer.

Longer head-to-heads if you want them: Callie vs Cal AI and Callie vs MyFitnessPal. Broader field: Best AI Calorie Tracker Apps of 2026.
