Protein Pic vs MyFitnessPal vs Cal AI
Three apps, three jobs. MyFitnessPal is the full nutrition journal. Cal AI is snap-to-calories (and macros). Protein Pic is snap-to-protein—one daily number, less spreadsheet.
This page is an honest comparison. No fake accuracy scores. Pricing is what was publicly listed or commonly reported as of early October 2026; labels note anything that A/B-tests or we could not verify live in each App Store region.
Quick take
If you want
Full calorie + macro diary, huge food database, Android + iOS

MyFitnessPal
If you want
Fast photo → calories + full macros (protein, carbs, fat)

If you want
One protein target, camera-first, minimal logging friction

Protein Pic
You can use more than one. Many people keep MFP for history and use a snap app for dinner. The question is which app owns the habit you’ll actually open every day.

Where MyFitnessPal wins
Depth and durability
MFP is still the default food diary for millions of people. If you need years of history, a massive branded-food database, barcode-first packaged logging, exercise sync across many devices, and a free tier you can actually live in, MFP wins.
Full nutrition, not one macro
Custom macro goals (Premium), net-carbs mode, intermittent fasting tools, meal planning (Premium+), voice log, and a broader dietitian-and-trainer framing. If protein is one line in a bigger plan, MFP is built for that.
Platform coverage
Android and web matter if your household or coach isn’t all-iPhone.
Tradeoff: Speed. Manual search and serving sizes are the classic friction. Premium meal scan, barcode, and voice help, but the product identity is still a complete journal—more fields, more decisions.
Where Cal AI wins
Snap → full macros
Cal AI’s headline is photo logging for calories and protein, carbs, and fat. If your goal is a calorie budget with macro balance, that single-photo workflow matches the job better than a protein-only app.
Same price band as Protein Pic (often)
The most commonly reported Cal AI Premium offer is $9.99/mo or $29.99/yr—similar to Protein Pic’s Apple in-app purchase. Treat that as commonly shown, not guaranteed. Cal AI is widely reported to A/B-test paywalls.
Android
If you need photo macros on Android, Cal AI covers a platform Protein Pic does not yet.
Tradeoff: Cal AI is a calorie-first tracker with AI photo as the hook. Free without Premium is limited for the photo feature people came for (commonly reported). Accuracy on mixed and restaurant plates is debated in public reviews across the category. We do not claim a winner on accuracy here. No independent head-to-head with Protein Pic is cited on this page.
Context (public, 2026): Cal AI was acquired by MyFitnessPal (announced March 2026) and continues as a standalone app. Subscriptions are separate—MFP Premium does not unlock Cal AI (confirm current terms in each store listing).
Where Protein Pic wins
Protein is the product
Protein Pic is for people whose daily job is “hit X grams of protein,” not “balance four macros and a calorie budget.” The UI and the path to download are built around one number.
Snap → protein count → edit → save
Camera-first for real plates (home, takeout, restaurants). AI names food and estimates portions; you can edit before you save. Barcode and menu scan help packaged and restaurant choices. Built for the protein job, not a lab spreadsheet.
Accountability that matches the job
Streaks and groups oriented around daily protein—useful for gym friends or household accountability without turning dinner into a group calorie audit.
GLP-1 protein protection framing
When appetite is low, protein is how many people protect muscle. Protein Pic is a wellness and protein tracker, not a dose or shot tracker. If that is the job, a calorie-first app adds noise.
Price for the narrow job
At $9.99/mo or $29.99/yr (3-day trial), you are not paying MyFitnessPal Premium rates for a full diary you may not open.
Tradeoffs (honest)
- iOS only today—no Android.
- Not a full calorie or all-macros diary. If you need carbs, fat, and calories as first-class every day, Cal AI or MyFitnessPal fit better.
- Early social proof. The App Store rating on this marketing site is 5.0 from 2 ratings. Treat that as an early signal, not a crowd. Read the live listing.
- We do not publish a “percent more accurate than Cal AI” claim. Photo estimates are estimates. Edit-before-save is how Protein Pic handles uncertainty.

Who should pick which
Choose MyFitnessPal if you want the industry-standard food diary, Android and web, custom macros across the board, or you already live in MFP and only need Premium for speed tools.
Choose Cal AI if you want photo logging for a calorie and full-macro budget and you are fine with a calorie-first product (and you verify the paywall offer you are shown).
Choose Protein Pic if your north star is a protein gram target—gym, muscle, or GLP-1 protein protection—and you want the shortest path from plate photo to that number on iPhone.
FAQ
Is Protein Pic a MyFitnessPal killer?
No. MFP wins on breadth. Protein Pic wins when protein is the only daily score that matters.
Is Protein Pic just Cal AI for protein?
Related category, different job. Cal AI optimizes for full macros from a photo. Protein Pic optimizes for protein adherence and habit (streaks and groups) around that one target.
Do you have a free forever plan like MFP?
Protein Pic is free to start with a short trial, then a subscription. MFP’s free diary is more complete for long-term unpaid use.
Android?
Not yet. Use MFP or Cal AI if you need Android today.
Accuracy?
No app should promise perfect grams from a photo of a mixed plate. Protein Pic lets you edit before save. We do not invent head-to-head accuracy stats on this page.
