Illustrative day. Knoomi uses soft windows, never an exact hunger appointment.
The difference
A calorie budget isn’t a plan.
Other apps tell you how much to eat. Knoomi works out when, what and how much — around your work, your training and your bedtime.

Same budget. Now it’s a day you can actually live.
Illustrative day. Yours is built from your food, your calendar and your goal.
Hunger, predicted
Hunger doesn’t have to catch you by surprise.
Knoomi estimates how long each meal is likely to hold you and times the next one around it, so the day connects — no running on empty before lunch, or before dinner.
Same budget. Different clock.

Your meals, not a meal plan
Your food.Made to work harder.
No generic meal plans. Knoomi keeps the meal you wanted and changes what matters — a portion, an addition, a removal or a swap.
Burger + yogurt & berries
Keep the burger exactly as it is. The fries become a pot of Greek yogurt and a handful of berries.

241 calories lighter — and it carries you longer, not shorter. The burger never left the plate; the fries did.
Coverage is Knoomi’s estimate of how long a meal holds you — soft windows, never an exact hunger appointment.

Training days are fuelled first — then they carry more of the week's cut, because there is more room left on them.
It reads your training, movement, sleep and weight trend. It can’t see hormones, stress or illness, so when the evidence is thin it eases off. How this works →
In the moment
Hunger, or just the urge to eat?
When you’re hungry before your next meal, Knoomi suggests trying something small first, checks back, and re-plans the day if you’re still hungry.
- 14:10pm
“Hungry already?”
Dinner is planned for 7:30. Lunch is likely still covering you.
- 2Try first
“Let’s try something small first.”
- 315 minutes later
“Did that take the edge off?”
- 4Re-plan
Added — the rest of today is re-planned around it.
Knoomi adds a small snack or moves the next meal earlier, and resizes the rest of the day to fit.
Either answer is useful. Your plan adapts to what you tell it.
Illustrative times. You can always skip the test: “I know I’m hungry — skip this.”
Going out
Going out? Already planned for.
Tell Knoomi where you’re eating and roughly when. It plans the rest of your day around it, so you don’t starve to make room.
- 8:00amBreakfast you’d recognise.Your usual kind of breakfast, with the protein kept up.
- 12:30pmLunch, just a little lighter.Still real food, still enough, with a little less fat and carbs so there’s room for tonight.
- 4:30pmA small snack to carry you.Something with protein in the afternoon, so you arrive at dinner hungry, not starving.
- 8:30pmDinner out with friends.Order what you want. The room for it was kept all day.
Lighter early, room saved for tonight.
You don’t starve all day. The day still lands inside your goal.
An illustrative day. Knoomi sizes yours from your budget and the meal you tell it about.

Weigh-ins
The scale tells a noisy story. We explain it.

Scale 81.20 kg, reads as about 79.74 kg. Takes off ≈1.46 kg. ≈0.40 kg of it is likely water from food. It fades in a few days.

Questions, answered
Knoomi is a food decision system, not a calorie counter. You choose what you want to eat; it tells you how that meal fits before you eat it, and rebuilds the rest of your day around what you actually ate.
