Sigma Fitness

Sigma Fitness is your all-in-one fitness dashboard. It brings together your workouts, nutrition, sleep, and recovery data from Apple Health into a single, clean interface — so you can see the full picture and stay on track.

DASHBOARD Your Today tab gives you a complete snapshot: scheduled workout, calorie and protein progress, last night's sleep, resting heart rate, and HRV — all at a glance.

WORKOUTS Plan your week with a customizable training schedule. Start a workout with a live timer and heart rate monitor, or log sessions manually. Track your history and see your consistency over time.

NUTRITION All your macros — calories, protein, carbs, and fat — are read directly from Apple Health. Check off your meals (breakfast, lunch, dinner, snack) and browse meal inspiration with ingredients and macro breakdowns.

SLEEP & RECOVERY See how well you slept last night with detailed sleep data. Monitor your resting heart rate and heart rate variability to understand your recovery status.

SUPPLEMENTS Track your daily supplements with custom schedules. Check them off each day and never miss a dose.

SCIENCE-BACKED TARGETS During onboarding, Sigma calculates your personalized calorie and protein targets using the Mifflin-St Jeor formula, adjusted for your body stats, activity level, and fitness goal. You can see exactly how your targets are calculated in Settings.

APPLE HEALTH INTEGRATION Sigma reads 30+ health data types from Apple Health including heart rate, sleep analysis, body measurements, nutrition, workouts, VO2 Max, and more. Your data stays on your device — private by design.
