Arcal vs Cal AI
Arcal and Cal AI use the same core idea: photograph your plate and let AI estimate the macros. The real differences are not in the pitch, they are in pricing transparency, who owns the app, and how each has handled App Store rules.
| Arcal | Cal AI | |
|---|---|---|
| Primary logging method | AI photo scan | AI photo scan |
| Pricing shown before download | Yes, listed on the pricing page: $9.99/mo or $49.99/yr | No public pricing page; shown only after an onboarding quiz, historically A/B tested |
| Ownership | Independent | Acquired by MyFitnessPal, March 2026 |
| App Store history | No removals | Temporarily removed in April 2026 over deceptive billing design and IAP bypass, later reinstated |
| Ads | None | None |
| Social features | Private, opt-in friend sharing | Public accountability groups |
| Data policy | No selling your food diary, data syncs only through your own account | Now part of MyFitnessPal's data ecosystem post-acquisition |
The honest take.
The two apps solve the same problem the same way, so this comparison is closer than most. Cal AI has a longer track record and a much larger user base. Arcal's differences are structural: pricing is public before you download, the app is still independent rather than owned by the category's largest incumbent, and there is no history of an App Store enforcement action over billing design.
