Usage Examples

What's my TDEE? I'm 175cm, 75kg, male, moderately active:
→ tdee_calculator({ height: 175, weight: 75, age: 30, sex: "male", activityLevel: "moderate" })

Calculate my macros for a 2200 calorie cut:
→ macro_calculator({ calories: 2200, goal: "cut" })

What's my one-rep max from 100kg × 5 reps?
→ one_rep_max_calculator({ weight: 100, reps: 5 })

What pace should I run to finish a half marathon in 2 hours?
→ running_pace_calculator({ distance: 21.1, targetTime: 120 })

    TDQS

    A3.5/5.0

    Scored across 15 tools

    Disambiguation5/5

    Each tool addresses a distinct health metric (BMI, BMR, TDEE, macros, body fat, etc.) with no overlap in purpose. Even closely related calculators like BMR and TDEE are clearly separated by their descriptions.

    Naming Consistency4/5

    Most tools follow the pattern of 'descriptor_calculator' (e.g., bmi_calculator, bmr_calculator). Two converters (kj_to_calories_converter) and two sleep tools (sleep_calculator, sleep_debt_calculator) deviate slightly from the dominant '_calculator' suffix, but the naming is still predictable.

    Tool Count4/5

    15 tools is reasonable for a health calculator suite covering body metrics, nutrition, fitness, and sleep. It is at the upper end of the typical range but each tool serves a distinct function without feeling excessive.

    Completeness4/5

    The set covers the core health calculation domains well: body composition (BMI, body fat, ideal weight), energy (BMR, TDEE, calories), nutrition (macros, protein), fitness (1RM, heart rate, VO2max, pace), and sleep. Minor gaps like hydration or calorie conversion from calories to kJ are absent, but the core lifecycles are complete.
