The three numbers on your Burnie home screen, explained simply
You open Burnie and see three numbers: your daily deficit, your BMR, and your active calories. Here is what each one means and how they work together to tell your body's story for the day.
You open Burnie. Three numbers stare back at you from the home screen. One is your daily deficit — the gap between what you ate and what you burned. One is your BMR — the energy your body burns just to stay alive. One is your active calories — the extra energy you burned by moving. They look like three separate tiles. But they are actually one maths sentence, split into pieces. This is your plain guide to reading all three together.
The three numbers and what each one means
Each tile answers a different question. Your BMR is the energy your body burns at rest — breathing, heartbeat, body heat. Scientists say BMR is about 60% of all the calories you burn in a day. Your active calories is the extra energy you burn by moving — walking, chores, a quick gym session. That slice is about 30% of your daily burn. Your daily deficit is the gap left over. Burnie finds it with one maths line: food minus (BMR plus active calories). If you ate 1800 kcal and your BMR plus active calories is 2200 kcal, your deficit is 400 kcal. You burned 400 more than you ate. That is the whole story in one line.
The three numbers side by side
Only the deficit number matters. The other two are just for show.
mostly falseMostly false. The deficit is the result, but it is built from the other two. If your active-calories tile looks too low, your deficit shrinks even if you ate the same food. If your BMR tile looks wrong, the whole maths shifts. Reading all three helps you see WHY your deficit is what it is. A low active number might mean your phone sat on the desk. One study found iPhones undercounted daily steps by about 12%. You can fix that by typing your own active calories in Burnie. All three numbers work together.
How to read your three numbers together
The bottom line
Your Burnie home screen shows one maths sentence in three pieces. Your BMR is the big at-rest burn, about 60% of your day. Your active calories is the movement slice on top, about 30%. Your daily deficit is the gap: food minus (BMR plus active calories). Read the deficit first, then check the other two to see how you got there. Burnie never reads your heart rate, sleep, blood pressure, or location — only your food, weight, and phone movement. And it is free, with no paid tier. Three tiles, one story: how your day went.
