Two AI-first food scanning apps, compared honestly. Updated September 6, 2026 · Comparison sources: August 2026
BodyDexCal AI focuses on photo logging. BodyDex combines food, workouts and protocol tracking.
Both apps lean on AI photo recognition for fast food logging. Cal AI is a focused, subscription-only AI calorie tracker available on iOS and Android — acquired by MyFitnessPal (announced March 2026), running as a standalone app on MFP's food database. BodyDex pairs AI scanning with a full database-backed manual log, an AI nutrition coach, peptide & protocol tracking, and on-device data storage — on both iOS and Android, with a permanent free tier. If you want the most depth, choose BodyDex. If you want a minimal AI-only experience and don't mind paying day one, choose Cal AI. New to photo logging? See how AI calorie tracking from photos works.

AI fails on edge cases — homemade dishes, regional foods, low-light photos. BodyDex's database search and barcode scan are full features, not fallbacks — and you can fix a wrong scan by saying what's off (see the voice logging guide). Cal AI is more AI-only by design.
Beyond logging, BodyDex includes an AI coach that can answer questions about your data — "am I hitting my protein this week?" — grounded in your actual logs.
BPC-157 cycles, GLP-1 doses, supplement schedules with reconstitution math and supply alerts. Cal AI doesn't address this audience.
Your food, weight, and protocol logs live on your device, not in a BodyDex database. For sensitive personal health data, that's a stronger privacy posture by default.
We have not published a head-to-head accuracy study of BodyDex and Cal AI. Photo estimates can miss ingredients, preparation methods and portion sizes, so review each result. Weighing portions and checking food labels or database entries can reduce uncertainty. BodyDex provides FatSecret, USDA and Open Food Facts lookup alongside editable AI results, so you can correct a scan before logging it.
Pick BodyDex if you want AI scanning AND deep manual logging, peptide / protocol tracking, free custom macro goals, an AI nutrition coach, and on-device data storage. Both apps are available on iOS and Android. Pick Cal AI if you specifically want a minimal AI-only experience.
No. BodyDex stores all your food logs, weight history, recipes, and protocols locally on your device — there is no centralized BodyDex database of user food entries. Cal AI is account-based with server-side storage. If on-device-only matters to you, BodyDex is the option.
Cal AI has no public pricing page — you see a price after the onboarding quiz and a 3-day trial, and the paywall is heavily A/B-tested, so different users see different offers (commonly ~$2.99/week, $9.99/month, or $29.99/year). BodyDex Premium is $9.99/month or $79.99/year. The bigger difference is what's free: in BodyDex the manual food log, recipes, weight tracking, and peptide/protocol tracking (up to 2 active protocols per category on free) are usable on the free tier; in Cal AI, after the trial ends without payment the app becomes a basic manual food logger and AI scanning stops working.
Yes — MyFitnessPal announced its acquisition of Cal AI in March 2026. Cal AI continues as a standalone app but now uses MyFitnessPal's food database. BodyDex is independent and not affiliated with either company.
No — Cal AI is a calorie tracker, not a protocol tracker. BodyDex was built with peptide and protocol tracking as a first-class data type, including dose schedules, reconstitution math, and supply alerts. See our peptide tracker guide for details.
