Calorie Burndown

It doesn't log your food. It reads what already lands in Health and answers one thing: are you on pace today? Every feature free — no paywall, no account.

Calorie Burndown answers one question the Health app doesn't: given what you've eaten and burned today, how much room do you have left? It reads those numbers straight from HealthKit, does the arithmetic against a goal you set, and shows the answer on your phone, your Lock Screen, and your wrist.

WHAT YOU'LL NEED Calorie Burndown doesn't log food and doesn't estimate your metabolism — it reads what's already in Health. So you'll want a calorie-tracking app writing what you eat to Health, and an Apple Watch recording what you burn. If you already track both, this turns them into a number neither one gives you. If you don't, this app has nothing to read and won't be much use.

EVERY FEATURE IS FREE No paywall, no subscription, nothing locked. The in-app purchases are optional tips — they unlock nothing, and the app behaves identically whether or not you ever use them.

WORKS EVERYWHERE YOU DO

• iPhone app with an iPad-optimized layout
• A home screen widget that shows your remaining budget at a glance
• Lock Screen widgets, so it's there without unlocking
• A watchOS companion app with real-time numbers, even without your phone nearby
• Watch face complications and Smart Stack widgets

BUILT ON HEALTHKIT, NOT A SEPARATE DATABASE There's no food database here, no barcode scanner, and no second place to log things. Keep using whatever app you already use; Calorie Burndown reflects it automatically. Your health data is read on your device and never leaves it — there is no account, no server, and nothing to sign up for.

YOUR WATCH WORKS ON ITS OWN The Watch app queries HealthKit directly, independent of your phone, so you get a real-time deficit number on a run or at the gym even if you left your phone at home. Settings and progress stay in sync across devices whenever they're near each other.

WEEKLY CHECK-IN AND TRENDS A simple weekly check-in helps you see the bigger trend, not just today's number, and History charts your weight against the pace your target implies.

IF YOU WANT TO SAY THANKS Settings has a tip jar with three sizes. That is the only place money is ever mentioned. It grants no features, removes no limits, and nothing in the app changes if you skip it.

Calorie Burndown does not diagnose, treat, or provide medical advice — it's a simple deficit calculator built on data you're already tracking in Health.
