Calorie Burndown
Calorie deficit, from Health
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
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.
more The widget's trend arrow is gone. It sat next to the figure with nothing to say what it measured, so it read as decoration at best and a second, confusing number at worst. VoiceOver still reads out how far the day has moved against pace.
The weight trend chart could report you slightly ahead of or behind schedule depending on what time of day you first set your goal. Your target is now treated as a whole day, so the verdict stays put.

The weight trend chart could report you slightly ahead of or behind schedule depending on what time of day you first set your goal. Your target is now treated as a whole day, so the verdict stays put.
A number sat beside the widget's trend arrow with nothing to say what it measured. The arrow now stands on its own, and VoiceOver reads out how far the day has moved against pace.
1.8.2 Oct 24
The chart on the widget no longer vanishes a couple of hours after you open the app. It keeps up with the numbers beside it all day now.
Open the app the morning after you last used it and it no longer shows yesterday's figures for a moment before today's arrive.
Your numbers appear faster at launch — the app was waiting on a reading it didn't need in order to show them.
And when there genuinely isn't a chart yet, on a new install or early in the day, the large widget says so instead of leaving a gap.
1.8.1 Oct 23
The widgets, rebuilt.
Every size now does a different job instead of showing you the same thing three times. The small one is the number and which way it's moving. The medium one gives the day's curve the room it needs, and marks the gap between where you're heading and where you need to be — that gap is the figure above it, drawn. The large one is new: the full day, plus what the rest of it would take.
There's also a ring, if a gauge reads faster to you than a line.
They're translucent now, so they sit in your wallpaper rather than on top of it, and they look right in dark mode.
Meals logged ahead land in the right place.
If you log dinner at breakfast time — budgeting it before you eat it — the chart was counting those calories in the number at the top while leaving them out of the line beneath it, so the two disagreed. The projection now steps down at the hour the meal is set for and finishes on the figure above it.
Also in this release: food is called "Logged" rather than "Consumed", since it may be food you've planned rather than eaten; the Watch's History screen gained your average intake for the week; and three figures on the iPhone that were showing calories to people who read kilojoules now convert properly.
1.8 Oct 18
History, on your wrist.
The Watch app can now tell you where you stand without reaching for your phone: your streak, how many days you've hit this week, your success rate, the last seven days one by one, and your weight trend drawn against the target. It's the glanceable half of the iPhone's History tab — the full thirty-day breakdown stays on the phone, where there's room to scroll it.
Burndown asks Health which units you use.
It used to guess from your region, which is right until it isn't: a scale that reads kilograms in a country that says otherwise meant translating every figure in your head. Now it asks Health what you already work in and follows that. You can still change either unit in Settings.
If you weigh yourself in stones, it shows stones — "11 st 4", the way it actually gets said, rather than a single number in pounds nobody uses out loud. Weight changes stay in pounds, because "I lost three pounds this week" is still how a week gets described.
Also in this update:
- The weight trend's goal line now starts where you set the goal. It used to anchor to the oldest weigh-in on screen, which moved forward every day — so a goal set this morning could be scored against a month that came before it, and the verdict could change overnight without you touching anything.
- Setting a goal on the Watch now respects your units. A target typed in kilograms was being saved as pounds, and a deficit typed in kilojoules as kilocalories, on both devices.
- The target weight row no longer wraps onto two lines in stones.
- The weekly check-in and Settings now describe your goal in the same words and the same units.
1.7 Oct 9
Fixes from the first days of 1.6.
Resting energy was going missing. The app reads your Health data hour by hour, and resting energy arrives in long stretches that cross from one hour into the next — those were being discarded rather than counted, so it could read your resting burn as zero. Depending on where it landed, that showed up as History crediting only what you had actively burned, as days marked missed that you had actually hit, or as the Today screen refusing to show anything at all and telling you it could not read your Health data. It could read it the whole time. Thank you to the tester who kept reporting this until it made sense.
The chart on your Watch complication kept disappearing between visits. The app refreshes those figures in the background every fifteen minutes or so, and the shape beside them was being started and then abandoned each time, so unless you had just opened the app there was nothing to draw. It now finishes the job.
Opening the app is quicker. It was reading your Health data up to seven times at once on launch, each read slowing the others down, and the "Reading your Health data" screen stayed up for all of it. Now it reads once.
Also in this update:
- If you have entered your resting energy manually in Settings, History now uses it. Every other screen already did, so your days were being scored against a figure the rest of the app had agreed to use.
- Each check-in time in Settings says when it will next arrive. Changing one to a time that has already passed schedules it for tomorrow, and the weekly review moves within its own day — both correct, neither obvious, and now both visible.
- The Watch app no longer briefly shows an empty space where the chart belongs while it waits for your resting energy to load.

1.6.1 Sep 25
Kilograms and kilojoules, if that's what you use.
Burndown now shows weight and energy in the units of your region, picked automatically — so a scale that reads kilograms and a label that reads kilojoules no longer need translating in your head. Everything follows: the daily figure, the chart, the widgets, the Watch, the goal you type in, and the page explaining the arithmetic. You can change either unit in Settings, and your goal is stored the same way whichever you pick.
The day's shape, on your wrist.
The Watch app draws the same burndown curve the iPhone shows: what your deficit actually did today, the pace your goal asks for, and where the day lands if nothing more is logged. It sits under the figure rather than a scroll away, and the Smart Stack widget draws it beside the number too. It's read on the Watch itself, so it's there on a run with no phone nearby.
The number now carries its own direction: +680 means ahead of your goal, -340 means behind. The word underneath is gone, because a sign works whether or not you can tell the colours apart.
Also in this update:
- Choose when the check-ins arrive. Midday, evening and the weekly review each have their own time, and the weekly one has its own day — so it no longer has to land on a Sunday morning.
- The goal's manual switch now sits with the target weight and date it applies to.
- The notifications section explains what it schedules instead of repeating a privacy line from the section above it.
- A card on Today no longer sits with a wider margin than the cards around it.
- The Watch chart no longer disappears for the rest of the day when a single reading is missed, and the widget keeps it refreshed between visits.

1.6 Sep 23
The Home Screen widget now says when it last updated.
If the small widget and the app ever showed different numbers, this is why. The widget's figures are written minutes apart from the app's, and at the small size nothing on the tile said when — so a reading that was a little behind looked like a disagreement. The time now sits beside the status, the way the larger widget has always shown it.
Also in this update:
- Setting the app up on a new phone no longer opens straight into a weekly check-in. It used to greet a fresh install with a review of a week it had never seen; the first check-in now arrives a week after you start.
- VoiceOver says when a reading was taken, rather than leaving the time out.
- On a day where nothing was logged, VoiceOver names that day instead of calling it today.
1.5.4 Sep 19
Fixes the app going blind after you change Health permissions.
If you turned Burndown's access to Health off and back on again, the app kept showing nothing until you force-quit and reopened it. It now re-reads your data whenever you come back to the app, so restoring access is enough on its own.
Also in this update:
- When a Health read fails, the app keeps the last figures it actually read instead of presenting a confident day built from nothing, and it no longer tells you Health is empty when the truth is that it couldn't read.
- The Health permission screen now explains everything Burndown reads — the calories you've eaten and burned, and your weight — rather than naming only one of the four.
Thanks to the tester who reported the permissions bug and confirmed the fix.

1.5.3 Sep 16
Fixes a dead end on the History screen.
If your history hadn't loaded, the "Load history" button did nothing at all — no spinner, no error, no change. It was being treated as a duplicate of the automatic load the app already runs at launch, so tapping it was skipped. It now always does what it says.
Also in this update:
- The weekly summary no longer says you're off pace while the check-in says you're on track.
- Figures over a thousand in the weekly summary now group their digits, like every other number on the screen.
Thanks to the tester who reported the History bug, with the detail that made it findable.
1.5.2 Sep 11
Burndown now tells you when your Health data last arrived.
If your iPad and iPhone ever disagree, this is usually why: Health reaches an iPad through iCloud rather than directly, and can run an hour or more behind. The app says so plainly instead of leaving you to wonder, and How It Works explains the whole thing.
Also in this update:
- The weekly summary and the weekly check-in no longer describe the same week in different terms.
- The last 7 days chart labels every day, so you can tell which day a bar belongs to.
- The weekly check-in no longer offers to discard changes you haven't made.
Every feature is still free. No paywall, no subscription, no account.
1.5.1 Sep 9
The pacing line on Today could tell you that you were right on pace while the day was going to fall well short — and the chart directly above it showed exactly that, with your line far below the dashed goal pace. It was comparing a whole-day projection against a part-day expectation, so on a day where nothing changed it drifted from "ahead" in the morning to "behind" by night. It now compares where your day actually is against where the pace line actually is, at the same moment, so the sentence and the chart agree.
You may see "behind pace" on days that used to read "on pace". That is the correction.
The suggested walk or run got longer, and honest. It used to offer a number that would have left you short of the goal it promised to reach.
You can now check today's figure without opening the app. Swipe down on the Home Screen and type "burndown", or find "Today's burndown" in the Shortcuts app. It won't invent an answer: if you haven't logged any food yet, or the numbers are from an earlier day, it says so instead of reading out a figure.
Settings has a new iCloud section with a switch for syncing your goal between devices. It's on by default. Turning it off stops this device syncing and removes what it had stored in your account — and it tells you plainly that another device still syncing will put its copy back.
For VoiceOver users: the app could read old numbers aloud as though they were current, even while the screen said they were stale. It now says how old they are, or declines to give a figure, matching what is on screen.
On the two days a year the clocks change, the hourly chart assumed every day is 24 hours long. It dropped an hour in November and drew a flat invented one in March. Your totals were always right; only the shape of the chart was wrong.
1.5 Sep 4
Fixes, no new features.
The figure at the top of Today used to turn amber whenever you had calories left,
even when you were comfortably ahead of pace — so a day going well read as a
warning, with a green "ahead of pace" line directly beneath it disagreeing. It
now goes green when you are ahead.
Today's weekly card said "This week" over a window that was actually the last
seven days. It says "Last 7 days" now, which is what it shows.
On a device with no history loaded yet, that card showed "0 of 7 days hit" and
"0.0 lbs" — a confident zero over a week it knew nothing about. It now shows
dashes until it has something true to say.
On iPad, Today and History rendered in a narrow column with much of the screen
empty. Both use the width now.
The watch's goal screen gained the warnings the iPhone already had: a note when a
goal is aggressive, the daily intake that goal implies, and a reminder to talk to
a doctor. Setting a goal there used to be silent no matter how extreme.
Notifications no longer claim things they have not checked — the evening one used
to say there was still time to close the gap whether or not there was a gap.
Smaller things: the chart legend's dashed markers no longer run into their
labels; the weight trend says "behind schedule" rather than "behind the pace this
target implies"; the watch no longer breaks "915 cal/day" across two lines; and
history loads faster.
Known: after updating, your watch complication may need removing and re-adding.
That is a watchOS behaviour we have not found a way around.
1.4.1 Sep 2
A redesigned Burndown.
The app now follows Apple's design language throughout — system colours, full Light and Dark Mode, and native typography in place of the old monospaced look.
Today now leads with the shape of your day: a chart of what your deficit actually did, hour by hour, against the pace your goal asks for. You can see when you got ahead and when a meal pulled you back — something a single number can't tell you.
The home screen widgets are redrawn to match, and show that same curve.
New: your goal syncs across your devices through iCloud. Set a target date on your iPhone and your iPad picks it up, instead of each device working from its own.
Resting energy is more accurate from your first day. It now uses whatever Health has rather than waiting for a full week of history, and a day you wore your watch for only part of the time is no longer counted as a short day.
VoiceOver support throughout, and the whole app now reads correctly at larger text sizes.
Note: after updating, your watch complication may need removing and re-adding. This is a watchOS behaviour rather than something the app can fix.
1.4 Aug 31
Your resting energy average no longer changes as the day goes on. It was averaging the last seven days including today, so it read low first thing in the morning and climbed steadily until midnight. Resting energy is the largest part of the calculation, so this moved your calories burned and your daily goal along with it.
Current weight now shows a decimal, so it agrees with the figure beneath it. A weight of 189.8 displayed as "190" over "19.8 lbs remaining" against a 170 lb goal was correct arithmetic that looked wrong.
The daily breakdown now reads PROJECTED BURN and PROJECTED DEFICIT. Those rows estimate where the whole day is heading, but they were labelled TOTAL BURNED and CURRENT DEFICIT — past tense, for numbers nothing had reached yet. At 4 AM the card claimed 1,880 calories burned when about 300 had been.
1.3 Aug 28
Clearing your goal now clears it everywhere. Previously your Watch could keep showing a deficit against a goal you had already deleted.
When there's no number to show — no goal set, no weight logged, no resting energy — the widgets and complications now say which one is missing instead of showing dashes.
Goal dates: you can no longer pick today as a target date, which never produced a usable goal, and if your target date passes the app now tells you rather than quietly carrying on.
History counts only the days you actually logged food, so "days tracked" reflects your real record.
Also: fixed two Settings labels that were cut off mid-word, one of which was hiding the fact that a negative goal sets a surplus for gaining weight.
If your Watch complication stops updating after an app update, removing it from your watch face and adding it back will sometimes clear it; restarting your Watch is the more reliable fix.
1.2 Aug 27
Lock Screen widgets, so your remaining budget is there without unlocking. A weight trend chart in History showing your weigh-ins against the pace your target implies. And goal projections now show a range with the number of logged days behind them, instead of a single date.
If your watch complication stops updating after an app update, remove it from your watch face and add it back — that clears it.
1.1 Aug 26
Fixes a dead link to weight-loss guidance, corrects progress reporting on days with no food logged, fixes goal setup when Health has no recent weight, and stops the day's pace being judged before it can be.
1.0.1 Aug 26
The widget's trend arrow is gone. It sat next to the figure with nothing to say what it measured, so it read as decoration at best and a second, confusing number at worst. VoiceOver still reads out how far the day has moved against pace.
The weight trend chart could report you slightly ahead of or behind schedule depending on what time of day you first set your goal. Your target is now treated as a whole day, so the verdict stays put.
