The nutrition and training app that shows the math behind every number

The scale lies. The trend doesn't.

You train, the scale won't move, and it feels like nothing is working. It is. When you build muscle and lose fat at the same time, your weight barely changes while your body does. kaliba figures out what to eat and how to train, then shows you the proof the scale hides.

Is this you?

You don't need another app. You need to see that it's working.

These are the moments we built for.

Back in the gym, but nothing's changingStuck at a plateauTired of counting caloriesStreaks made you quitPast 40, and your body stopped respondingBuilding muscle, unsure what to eatNew to all this, no idea where to start

Whichever one it is, the problem was never you. It was the feedback.

Why this time is different

An honest instrument that recalibrates you.

Effort was never your problem. Feedback was. Most apps either think for you, so you learn nothing, or leave you alone with numbers that mean nothing. kaliba does the opposite. It runs the math and shows its work, so you understand your own body while it changes. The number is the hero, not the app.

Calibrate the body. Calibrate the mind.

Signal and noise

Build muscle and lose fat, and the scale barely moves.

Your weight swings day to day from salt, water, and a hard leg session, not from fat. A kilo of body fat holds about 7,700 calories, so a kilo gained overnight is water, not a setback. kaliba reads the trend under that noise, a seven-day average, and tracks your waist and your strength next to it. That's how you watch body recomposition happen while the scale sits still.

A single morning lies. The trend doesn't.

How it works

It does the math. Then it shows you.

kaliba starts from your weight and how active you are, and figures out the calories you burn in a day. From there it sets your target, your protein, fat and carbs, and splits them across your meals. Every number sits one tap away from the reason behind it. When your weight moves, kaliba suggests a recalculation, and shows you why.

Three modes, one engine. Lose, maintain, build. Switch when your goal does.

Inside the app

Today. Food. Train. Log. Coach.

One engine. Food, training, and a record that learns you.

Today

Everything that decides the day, on one screen.

Calories left, today's macros, your trend weight, and the next session. Tap any number and you see the math behind it.

Food

A plan to eat from, not an empty log.

Every meal arrives with its own target, and the catalogue is built on Swedish groceries. Search an ingredient or scan the barcode on the package.

Train

The weight and the reps are already set.

The program follows your phase, and the next target comes out of your last session. You see the week's volume per muscle and write down how it felt.

Log

You'll stop starting over.

Every day you log stays, tagged by phase. A year from now this isn't an app you tried — it's the record of how you got here, encrypted and yours.

Coach

It doesn't do the math for you. It explains it.

Ask what you're actually wondering and get an answer built on the numbers in your own plan. The coach never invents a new target — it shows how the engine arrived at the one you have.

The coach

The engine does the math. The coach explains it.

The numbers always come from the engine – the coach never invents its own. It can see your plan, your trend and what you have logged, and it answers what you actually wonder: why the scale is stuck, what to eat tonight, whether to swap an exercise. When an answer rests on research, you see which – and how strong it is.

It remembers you
On Free the coach remembers seven days. With Premium it remembers your whole journey – and you can see what it remembers and ask it to forget.
It stays in its lane
Food, training, your plan, your trend. Ask it about anything else and it says so plainly and steers back.
It is not a doctor
kaliba is for adults, 18 and over. For injury, illness, pregnancy or medication the coach points you to a healthcare professional instead of guessing.
A conversation

Why is the scale stuck?

The coach remembers your earlier conversations

Your trend has been flat for nine days. Your average across those days is 2 030 kcal – 180 above your target of 1 850. That is enough to stall it, not to reverse it. Stay at 1 850 for another week and it will move again.

The coach's answers are written by a language model. Your question and the relevant data from your plan are sent to our AI provider – you approve that before the first answer and can withdraw consent whenever you like. What gets sent is spelled out in the privacy policy.

The part most apps miss

No streaks. No guilt. A record you'll actually want to keep.

A bad day is a point on a line, not a failure. kaliba never marks you red for going over. It teaches you the method as it runs it, so the knowledge stays with you, not the app. And it keeps your whole history, your weight, your strength, your notes, year after year. The longer you use it, the more it's worth.

Calm enough to stay with.

Our promise

We will never fake a review.

Every fitness app shows you strangers with perfect abs and five stars. Most of it is paid or invented. We'd rather show you the situations you already know, and the honest reason behind each one.

You ate well all week, and the scale is up on Monday.

Salt, water and a weekend, not fat. Your seven-day trend already knows.

Three weeks in, the scale hasn't moved, but your clothes fit better.

That's recomposition. Muscle up, fat down, weight flat. The tape measure and the trend see what the scale can't.

You hit a wall and want to cut harder.

Usually the plan just needs recalculating, not more suffering. kaliba flags it when your trend drifts.

You went over on a bad day.

One day is noise. The trend absorbs it. There's no streak to break, and nothing turns red.

When we have real reviews, they'll be real. Until then, honesty is the only badge we wear.

The app does the math. You just show up.

01

A few taps a day

Log a meal or a set in seconds. You don't need to know a thing about calories.

02

Home or gym

Dumbbells and kettlebells, or a full rack. The engine picks the moves either way.

03

Watch the trend

Weigh in regularly, let the noise average out into a line, and trust the direction.

Your data

What's private stays private.

Your weight, measurements and notes are encrypted at rest, on servers in the EU. Progress photos are end-to-end encrypted, so not even we can see them. You can export everything or delete your account whenever you want. kaliba is for adults, 18 and up.

Pricing

The whole engine is free.

Free isn't a trial that runs out. The instrument stays free: the math, your plan, your trend. Premium keeps your full history and adds the coach that remembers your whole journey.

Why kaliba gets it right over time

Other apps guess once. kaliba calibrates.

Most apps take your weight, height, age and sex, run them through a fancy formula, hand you an exact-looking number — and never touch it again. The catch: no formula knows what you actually burn. Two people with identical stats can differ by 10–15% from everyday movement and metabolism alone.

kaliba does the opposite. We start with a quick, honest estimate — then calibrate it against your real trend weight, week after week. After a couple of weeks your plan isn't built on a formula; it's built on how your body actually responds. The longer you use it, the more right it gets.

An exact-looking number isn't the same as a correct one. We chase the correct one.

Why you can trust the numbers

Other apps show testimonials. kaliba shows its sources.

Behind the app sits a knowledge bank. Every common claim about food, training and the body gets a straight answer, an evidence grade from A to D for how strong the research is, and links to sources you can open yourself. Where the evidence is thin we grade it low and say so — an instrument that always has an answer is a bad instrument.

Straight answers

Questions, answered with the math.

The scale jumped up overnight. Did I gain fat?+
Almost never. A salty meal or a hard session holds water. To gain a kilo of fat you'd have to eat about 7,700 calories over what you burn. Your seven-day trend tells the truth; one morning doesn't.
Do I need to know anything about calories?+
No. kaliba does the math and shows you how, so you learn it as you go instead of trusting a black box.
Can you really build muscle and lose fat at once?+
Yes, especially if you're new or coming back. Your weight stays flat while your body changes, which is why kaliba tracks your waist and strength, not just the scale.
Is my data safe?+
Your weight, measurements and notes are encrypted at rest on EU servers, and you can export or delete everything at any time.
Is this medical advice?+
No. kaliba is guidance built on nutrition science, not medical advice. You're responsible for your own health.

Stop guessing.

The scale will lie again tomorrow. The trend won't. Start free, no account.
