Tally: BMI & Body Fat Tracker

Tally is a calm, local-first wellness app for the numbers you actually track: BMI, basal metabolic rate (BMR), and estimated body fat—plus TDEE from your activity level.

THREE METRICS, ONE PLACE • BMI from weight and height • BMR with the Mifflin-St Jeor equation, then TDEE for daily energy needs • Body fat using the U.S. Navy circumference method (neck, waist, and hip when needed) Work in metric or imperial; Tally stores values in metric and shows what you prefer.

HISTORY AND TRENDS Every save is a new entry—nothing gets overwritten. Review your history, see how BMI or body fat is moving, and view a four-week projection based on your recent logs.

GOALS THAT STAY HONEST Set a target for BMI or body fat and see whether your current pace is on track. Insights stay in the app as short status messages, not medical claims.

GENTLE REMINDERS Optional weekly or monthly nudges to log again. Notifications stay on your device; permission is asked only when you turn reminders on.

YOUR DATA STAYS YOURS No sign-in, no cloud sync, no ads, and no in-app purchases. Measurements live in on-device storage on your iPhone.

LOOK AND FEEL Choose light or dark appearance and an accent color that matches how you use the app.

HEALTH NOTICE Tally provides estimates for general wellness only—not diagnosis, treatment, or medical advice. BMI does not separate muscle from fat; formulas have margins of error. Read the in-app Health Disclaimer before changing diet, exercise, or medication based on these numbers. When in doubt, talk to a qualified healthcare provider.
