Calorie Counter Fitness
Fat Burning Zone Tracker
Free · Designed for iPad. Not verified for macOS.
Your body burns carbs before fat. See exactly when the switch happens — and how to make it last longer.
You've been counting calories wrong — not the maths, the timing.
Your body burns stored carbs (glycogen) before it ever touches fat. Most days, if you're eating every few hours, your glycogen never empties. You stay in
carb-burning mode all day, even in a calorie deficit.
Calorie Counter Fitness shows you where you are in that cycle right now — and how your meals and workouts shift it.
FAT BURNING ZONES, LIVE
A real-time gauge tracks your liver glycogen throughout the day. Watch it fall after a workout, rise after a meal, and drop into the fat-burning zone as the
hours pass. Five zones from Fed to Ketogenic — you always know which one you're in.
KNOW WHEN THE SWITCH HAPPENS
The app predicts your next zone transition before it arrives. Heading into fat-burning in 45 minutes? You'll see it coming. No guessing, no waiting to feel
it.
LOG MEALS AND WORKOUTS, WATCH YOUR CURVE MOVE
Every meal and workout you log shifts your glycogen curve in real time. See exactly how a high-carb dinner pushes you back to Fed, or how a morning run burns
through your reserves faster.
TRACK WHAT ACTUALLY MATTERS
Log calories, carbs, protein, and fat for every meal. Your daily glycogen chart shows the full picture — how food timing and exercise combine to shape your
fat-burning window.
YOUR DAY AT A GLANCE
The home screen shows your current zone, time until your next transition, total calories, and fat-burning minutes accumulated today. Everything you need in
one view.
Download Calorie Counter Fitness and start seeing when your body actually burns fat.
