Fat Burned vs Khotwa

Ever wonder how much fat you actually burn in a day? FatBurn turns your Apple Health data into clear, actionable fat burn estimates — no guesswork, no calorie counting, no manual logging. Just open the app and see how much fat your body has burned today, during workouts, this week, and over your entire fitness history. HOW IT WORKS FatBurn uses established exercise physiology research to estimate fat oxidation from data already on your iPhone and Apple Watch: Heart rate samples from workouts and throughout the day Your age, weight, and biological sex from Health Workout duration, and intensity Calories are estimated using the Keytel formula (Keytel et al., British Journal of Sports Medicine, 2005). Fat burn is then calculated based on heart rate zone analysis — your body burns a higher percentage of fat at lower intensities and shifts toward carbohydrates at higher intensities. FatBurn classifies your effort into low, moderate, and vigorous zones and applies research-backed fat oxidation percentages to each. WHAT YOU SEE Daily Fat Burn — total fat burned from all activity and resting metabolism Workout Fat Burn — fat burned specifically during recorded workouts Weekly Trends — a 7-day chart showing daily fat burn with weekly totals Workout Breakdown — individual workout cards with fat burn, duration, and calories Lifetime Total — cumulative fat burned from your earliest HealthKit record Customizable Goals — set daily, workout, and weekly fat burn targets based on CDC and AHA guidelines All values display in grams or ounces, with support for kilograms and pounds for larger totals.

Khotwa reads the shape of your day, not just the size of it. Most step counters give you one number and leave you to interpret it. Khotwa scores every day on three things that actually matter — when you moved, how hard, and whether today fits what your body has been doing all month — and then tells you what to do about it. THE DAILY BRIEFING Once a day, Khotwa opens with a forecast: at this hour, on days like this, how often did you finish? Not "3,000 steps left" but whether you are going to make it, how many minutes of walking closes the gap at your own pace, and the hour you usually move anyway. Computed entirely on your device from your own history. THE KHOTWA SCORE One number out of 100, built from how your steps were spread across the day, how many were brisk, and how the day compares to your own baseline. A thousand steps every hour beats ten thousand in one burst, and the score says so. LOAD AND READINESS Acute against chronic load, the same measure endurance coaches use, so you know when to push and when a lighter day protects you. YOUR WALKS, WITH THEIR ROUTES Every session records its track and saves to Apple Health. Walks, runs, rides and gym sessions from your Watch or any other app appear here too, each ranked against your own history of the same sport. FRIENDS AND CHALLENGES Add people by username, compare weeks, and run private challenges. Your route and location are never shared — only totals. BUILT FOR ARABIC Arabic-first, right to left, with Hijri dates and prayer-time-aware reminders. Full English support.
