Calorie and macro tracking for iPhone
Track your food. That's the hard part done.
Photograph your plate. lehko names what's on it, weighs each thing and adds it up. No scales. No searching. No guilt.
Point at your plate — one photo is enough.
The whole method
One photo. Then it's done.
Point the camera at the plate and put the phone down. What comes back is a list you can read: each thing named, each thing weighed, and the number at the bottom.
- Reads the whole plate, not one thing on it
- Every item carries its own weight
- Seconds, not minutes
Point
No framing, no white plate.
Hold the phone over the food the way you would to send someone a picture of it. The whole plate, in one frame, at whatever angle you are already sitting.
Wait
Put the phone down.
It reads the plate while you pick up your fork. No sliders, no serving sizes to choose, nothing to confirm before it starts.
Done
A list, not a guess.
Each thing named and weighed, macros underneath, and one number at the bottom. Tap any line to change it. Then it's in the diary.

Analyzing your meal…
Reading the plate — just a few seconds.
Tap to change a portion. × for what wasn't on the plate — the item stays, it just stops counting.
Real food
It reads real food, not photo-shoot food.
Borscht. Yesterday's leftovers in a bowl. Three things on one plate that touch each other. That is what people actually eat, and it is what lehko was built to read.

Sweet potato and chickpea plate with couscous and a soft egg
- Mixed plates, where nothing is separated
- Home cooking, not a menu photograph
- Bowls and soups, not just what sits flat on a plate
Borscht with sour cream · a bowl of leftovers · buckwheat, an egg and whatever else was in the fridge
Calories and macros recalculate automatically from the weight

Wrong? Fix it in one tap.
It is an estimate, and it says so. An estimate you can correct in one tap beats a number you are asked to trust. Tap the line, set the grams, and everything above it recalculates.
- Grams on every line, editable
- Add what it missed, remove what isn't there
- The total follows your correction, not the other way round
Your number always wins.
Four ways in
Photo, barcode, text or search.
Four doors, all the same size. A packet has a barcode. A sandwich you already know is faster to type. Nothing here is a fallback for the camera failing.
Point at your plate — one photo is enough.
Photo
The whole plate, read at once.
Barcode
Packaged food, straight off the label.
Describe
Type or say it. Two eggs, rye bread, coffee.
Search
A food database, when you know the name.
The day
Your whole day in one ring.
Eaten, burned, and what's left. Left is the number in the middle, because it is the only one that tells you anything at seven in the evening. Macros and water sit beside the food, not on another screen.
- What's left, in the middle, all day
- Carbs, protein and fat as they fill
- Water on the same screen as the food
312 burned · not counted toward the goal
Day closed. Light.
Nothing to submit. Nothing to tidy up. It closed on its own.
Over time
Calm charts. Quiet notes.
Small, muted, and no bigger than they need to be. Weight with a seven-day average, so one heavy morning does not look like a verdict. A nutrition score you can ignore for a week without losing it.
- Weight, smoothed over seven days
- A month of days, at a glance
- A weekly note or two, and one thing to try
Tap a bar to see its date, exact score and rating.
This is your best streak yet
Once a week it tells you what it noticed, and one thing worth trying. Then it stops talking.
How it works
Three steps, and the third one is the only one you repeat.
- 1
Answer a few questions
Height, weight, what you're after. Two minutes, and every answer is editable later.
- 2
Get your numbers
A daily calorie target and three macro targets, worked out from what you told it.
- 3
Photograph your food
That's it. That's the part that repeats, and it takes one hand.
This pace is safe — no extreme deficit.
Every number is editable later in Profile → Goals.

Questions
Straight answers.
How accurate is it?
It is an estimate, and we will not put a figure on it — any single number we quoted would be true of one set of photographs and misleading about yours. What we will say is how it behaves: it is closest on ordinary portions, and it reads large, heaped plates lighter than they are. That is exactly why every line is editable in one tap. An estimate you correct is worth more than a number you have to take on faith.
Does it know food that isn't on a menu?
That is the part it was built for. Borscht, deruny, pierogi, żurek, a bowl of yesterday's dinner. It reads a mixed plate where things touch and overlap, and returns each thing separately with its own weight, rather than one tidy answer for the whole photograph.
What happens to my photos?
A photo is sent to be read, the reading comes back, and that is the end of its job. Photos are not sold, not published, and not used to train a model. Nothing in lehko is public — there is no feed, no profile anyone can see, and no social layer. You can delete your account and all of its data from Profile → Account → Delete Account, from inside the app.
What does it cost, and what do I get for nothing?
Water logging, weight logging and the daily target you get at the end of onboarding are free and stay free. Photo scans, your diary and Progress are lehko Premium: $29.99 a year, which begins with 3 days free, or $4.99 a month with no trial.
How do I cancel?
In your iPhone: Settings → your name → Subscriptions → lehko → Cancel. Apple handles the billing, so cancelling there is what actually stops it — deleting the app does not. If it is easier to ask a person, write to [email protected].
Is there an Android version?
Not yet. lehko is iPhone-only today. The Android build exists and is not finished, and we would rather say that than take a date we are not sure of.
Let it be light.
One photo a meal. That's the whole thing.
