StepKcal

Overview

StepKcal is a web-based calorie calculator that replaces vague activity-level estimates with real step-count data. By combining the Mifflin-St Jeor equation with daily step input, it generates a personalized Total Daily Energy Expenditure (TDEE), Basal Metabolic Rate (BMR), and calorie deficit plan. The tool targets individuals who track steps via phones or fitness trackers and want a science-backed, subscription-free approach to weight management.

Key Features

• Step-Based TDEE Calculation: Uses actual daily steps (not activity-level dropdowns) to estimate non-exercise activity thermogenesis (NEAT) and total energy expenditure.
• Mifflin-St Jeor Equation: Employs this validated formula for BMR, adjusted for age, gender, height, and weight.
• Personalized Calorie Targets: Outputs maintenance calories and multiple deficit options (e.g., 0.5 kg/week, 0.7 kg/week) based on desired weight and safe loss rates.
• Macronutrient Breakdown: Suggests protein, carbs, and fat grams for each calorie target (default 30/40/30 split).
• Weekly Weight Projection: Displays a table of projected body weight over weeks until goal is reached, for each deficit pace.
• BMI Assessment: Calculates BMI and shows position on a color-coded scale, with weight loss needed to reach healthy range.
• One-Time Purchase: No subscription or signup required; a single $1.99 fee unlocks the full report.
• Metric and US Units: Supports both unit systems with a toggle.
• Shareable Report: Generates a unique URL for the personalized report that can be shared or revisited.

Use Cases

• Health-Conscious Individuals: People who track steps and want a precise, data-driven calorie target without guessing activity levels.
• Weight Loss Seekers: Those aiming to lose weight at a safe, sustainable pace with clear weekly milestones.
• Fitness Enthusiasts: Users who combine step tracking with other exercise and need accurate TDEE for muscle gain or fat loss.
• Budget-Conscious Users: Individuals who prefer a one-time payment over recurring subscription fees for calorie calculators.
