Our Testing Methodology

How we evaluate nutrition tracking apps to provide accurate, unbiased reviews.

Hands-On Testing

Every app we review is personally tested for a minimum of 30 days. We use each app as our primary nutrition tracker during this period, logging real meals throughout our daily lives.

We test with a variety of foods including:

  • Simple single-ingredient foods (apple, chicken breast, rice)
  • Complex homemade dishes (stir-fry, casseroles, soups)
  • Restaurant meals and takeout
  • Fast food items
  • Packaged foods with nutrition labels
  • International cuisines

Accuracy Testing

For AI-powered apps, we measure accuracy by comparing app estimates to actual nutritional values. We calculate the "true" values by:

  • Weighing all ingredients on a kitchen scale
  • Looking up values in the USDA FoodData Central database
  • Calculating totals for complex recipes

We then compare the app's estimates to our calculated values across calories, macronutrients, and (where available) micronutrients.

Evaluation Criteria

We evaluate each app across multiple dimensions:

Accuracy (30%)

How closely do the app's estimates match actual nutritional values? We test across different food types and complexity levels.

Ease of Use (25%)

How quick and convenient is daily logging? We consider input methods, interface design, and the overall user experience.

Features (25%)

What capabilities does the app offer? We look at input flexibility, micronutrient tracking, coaching features, and more.

Value (20%)

Is the price justified by what you get? We compare features and quality against subscription costs and free alternatives.

Independence & Disclosure

Our reviews are editorially independent. We do not accept payment for favorable reviews, and our rankings are based solely on our testing results.

Affiliate Disclosure: We may earn a commission when you download an app through our links. This does not influence our rankings or reviews—we recommend the same apps regardless of whether we earn a commission.
