Which one to pick (by use case)

The right choice depends on what you actually need. Here's the per-use-case breakdown.

You want the fastest possible photo logging

Cal AI — Cal AI's photo-first UX returns calorie estimates in ~3 seconds. MyNetDiary has a Meal Scan feature but it's newer and slower. For pure speed, Cal AI wins.

You eat at fast-casual chains constantly

Cal AI — Cal AI inherits MFP's 380+ restaurant chain database post-acquisition. MyNetDiary focuses on whole-food and packaged-food data — chain coverage is weaker.

You want verified data (no crowd-sourced noise)

MyNetDiary — MyNetDiary staff-verifies every entry (2,000-4,000 foods reviewed daily) and pulls from USDA + NCC. Cal AI inherits MFP's 20M crowdsourced database with ~23% sample error rate.

You want to track micronutrients in depth

MyNetDiary — MyNetDiary tracks up to 108 nutrients per food (vitamins, minerals, amino acids, fatty acids). Cal AI inherits MFP's ~15 nutrients.

You manage diabetes or use GLP-1 medications

MyNetDiary — MyNetDiary has dedicated diabetes tracking (blood glucose, insulin, A1C) and two GLP-1-specific meal plans with curated recipes. Cal AI has no medical features.

Pricing certainty matters before downloading

MyNetDiary — MyNetDiary publishes $9/month or $60/year clearly. Cal AI's pricing varies $2.49-29.99/year and was briefly pulled from the App Store in April 2026 over deceptive billing.

You want a fully usable free tier

MyNetDiary — MyNetDiary's free tier includes barcode, 108 nutrients, water, food journal, no ads. Cal AI requires subscription for photo recognition.

My verdict

Cal AI is fast and has MFP's restaurant database. MyNetDiary is the verified-data choice with 108 nutrients, diabetes/GLP-1 features, and a real free tier. Eat out at chains often → Cal AI. Want clinical-grade data or have medical needs → MyNetDiary.

I'm building Nutrogine as a transparent alternative — not as a competitor that needs you to pick sides in this comparison.

Frequently asked questions

Is MyNetDiary more accurate than Cal AI?

On database quality, yes. MyNetDiary staff-verifies every entry from USDA + NCC sources (±4.8% calorie accuracy in testing). Cal AI inherits MFP's 20M-entry crowdsourced database with ~23% sample error rate, and Lifehacker testing showed Cal AI underestimating simple foods by 33% and misidentifying a Pink Lady apple as tikka masala.

How many nutrients does MyNetDiary track vs Cal AI?

MyNetDiary tracks up to 108 nutrients per food (sourced from USDA + NCC databases). Cal AI inherits roughly 15 from MFP's database — calories, basic macros, sodium, sugar, etc. — but not full vitamin/mineral profiles.

Which app is better for diabetes management?

MyNetDiary by a wide margin. It has dedicated tracking for blood glucose, insulin, A1C, and other medications, plus two GLP-1-specific meal plans with curated recipes. Cal AI has no medical features — it's a pure calorie estimator.

What was the Cal AI App Store removal in April 2026?

Apple pulled Cal AI on April 15, 2026 for using Stripe-embedded payments outside Apple's IAP system, plus deceptive billing UI showing weekly prices more prominently than the actual billed amount. Cal AI fixed the issues and was reinstated within a week — currently #4 in Health & Fitness.

Is MyNetDiary's free tier really better than Cal AI's?

Yes. MyNetDiary free includes barcode scanning, 108 nutrients per food, water tracking, food journal, no ads. Cal AI's photo recognition (its core feature) is paid-only — the free tier is essentially a marketing trial.

Is there a better calorie tracker for restaurant meals than both?

Both apps treat restaurant items as a database lookup — no source citations on portion sizes, no aggregation of customer-reported actuals. Nutrogine launches Q3 2026 specifically for restaurant tracking with USDA + brand + customer-report Source Badges on every number. Join the waitlist.
