In a digital era flooded with conflicting health advice, Fitness AI stands as a beacon of clarity. We offer a suite of tools that are fast, private, and incredibly accurate. Our mission is to democratize "Bio-Data"—giving you the precise numbers you need to understand your own biology.
Unlike most apps, our tools like the BMI Scanner and Macro Calculator run entirely on your device using Client-Side JavaScript. No personal health data is sent to our servers. This ensures absolute privacy while using our Visual Workout Planner.
Health isn't just one number; it's a connected system. We have organized our tools into three logical "Silos" to help you address every aspect of your well-being:
We do not use guesswork. All our calculators rely on peer-reviewed formulas such as the Mifflin-St Jeor Equation for metabolic rate and the Karvonen Formula for heart rate training. This commitment to scientific accuracy ensures that Fitness AI provides clinical-grade data for free.
