Calvin

Best for: Quick photo-based logging

Calvin takes a different approach than traditional calorie trackers. Instead of manually searching databases, you simply take a photo of your meal and AI identifies the foods and estimates portions.

Pros

• Fastest logging method: Photo → calories in seconds
• No ads: Clean experience even on free tier
• AI portion estimation: Don't need to measure or weigh
• Privacy focused: Photos processed securely
• Apple Health integration: Syncs with other health data
• Simple, beautiful interface: No feature bloat

Cons

• Smaller database for manual search (compared to MyFitnessPal)
• iOS only currently (Android coming)
• AI isn't perfect for complex mixed dishes

Pricing

• Free: 3 AI analyses per day, unlimited manual logging
• Pro ($39/year): Unlimited AI analysis, advanced insights

Our Take

Calvin is ideal if you want effortless tracking without the tedium of searching databases. The AI isn't 100% accurate, but it's close enough for most purposes and gets better with feedback. The lack of ads and clean design make daily use pleasant.

MyFitnessPal

Best for: Comprehensive database

MyFitnessPal has been the market leader for years, and their database shows it. With over 14 million foods, you can find almost anything.

Pros

• Massive database: Nearly every packaged food and restaurant
• Strong barcode scanning: Very high success rate
• Social features: Friends, challenges, community
• Integrations: Connects to most fitness devices and apps
• Recipe calculator: Import recipes from URLs

Cons

• Ad-heavy free tier: Constant premium upgrade prompts
• Cluttered interface: Lots of features, overwhelming for beginners
• AI features require premium: Photo recognition is paid only
• Database quality varies: User-submitted entries can be incorrect

Pricing

• Free: Basic tracking with ads
• Premium ($80/year): No ads, food verification, macros by meal

Our Take

MyFitnessPal is the reliable veteran. If you're a power user who wants every feature and doesn't mind navigating a complex interface, it delivers. But the aggressive ads and upselling on the free tier can be frustrating.

Cronometer

Best for: Micronutrient tracking

If you care about vitamins, minerals, and detailed nutrition beyond just calories and macros, Cronometer is unmatched.

Pros

• Detailed micronutrients: Track 80+ nutrients
• High-quality database: Verified USDA/NCCDB data
• Clean interface: Less cluttered than competitors
• Professional version: Used by dietitians and researchers
• One-time purchase option: Buy the mobile app outright

Cons

• Smaller database: Fewer user-submitted foods
• No photo recognition: Manual logging only
• Fewer restaurant foods: Better for home cooking
• Learning curve: Detailed tracking takes time

Pricing

• Free: Full tracking on web, basic mobile
• Gold ($50/year): No ads, advanced features, premium database

Our Take

Cronometer is the choice for nutrition enthusiasts who want complete data on what they're eating. The focus on verified, accurate nutritional data sets it apart from apps that accept any user submission.

Lose It!

Best for: Barcode scanning

Lose It! excels at making tracking fast and easy, with excellent barcode scanning and a clean mobile experience.

Pros

• Fast barcode scanning: Quick and accurate
• Clean design: Easy to navigate
• Good free tier: Decent features without paying
• Snap It feature: Photo logging with AI
• DNA and Lab integrations: Personalized insights

Cons

• Smaller database than MyFitnessPal: May not find every food
• Limited micronutrients: Basic macros only on free tier
• Social features require premium: Groups and challenges are paid

Pricing

• Free: Basic tracking with ads
• Premium ($40/year): No ads, advanced features, full nutrients

Our Take

Lose It! hits a nice balance between simplicity and features. It's not as comprehensive as MyFitnessPal or as detailed as Cronometer, but it's pleasant to use daily. The AI photo feature is decent but not as refined as Calvin's.

MacroFactor

Best for: Adaptive calorie recommendations

MacroFactor takes a data-driven approach, adjusting your calorie targets based on your actual weight changes over time.

Pros

• Adaptive algorithm: Learns your actual metabolism
• Quick logging: Efficient interface design
• Excellent coaching features: Smart recommendations
• Macro cycling: Easy to set up periodization
• Strong education: Explains the science

Cons

• No free tier: Subscription only
• Smaller database: Fewer foods than veterans
• Steeper learning curve: More complex than simple trackers
• No photo recognition: Manual logging only

Pricing

• $72/year (no free option)

Our Take

MacroFactor is built by nutrition nerds, for nutrition nerds. The adaptive algorithm is genuinely useful—it adjusts based on what your weight actually does, not just estimates. Worth it for serious trackers, but overkill for casual users.
