What the app does

Oven-baked salmon with potatoes and dill quark, plated — **Baked Salmon with Potatoes and Dill Quark**528 kcal, 39 g protein. Dinner, ready in 30 minutes. AI

01 Choosing

A swipe decides.

Right means I like it, left means rather not, up means definitely, down means never again. Four directions, and that is all the operation it takes.

A dish you have rated once does not come back in the stack. Whatever you swipe down is blocked for the whole household and is no longer used for planning. Whatever you like is given priority when planning.

This is a private preference, not a public rating. Recipes in KernBite cannot be rated, commented on, edited or uploaded.

02 Portions

Your amount, not the standard amount.

Every recipe is written for a standard portion. KernBite scales it up or down to your requirement using a portion factor. Nutritional values and shopping quantities grow with it.

Eight nutrition profiles determine how the calories are divided between protein, carbohydrates and fat. Allergens and intolerances rule out the affected recipes entirely. For ingredients you merely dislike there is the milder option: replace, leave out, or reduce the amount.

Pasta bake, plated — **Baked Pasta Gratin**520 kcal, 36 g protein. Lunch, ready in 30 minutes. AI

Fried rice with vegetables and egg, plated — **Fried Rice with Vegetables and Egg**739 kcal, 20 g protein. Lunch, ready in 20 minutes. AI

03 Shopping

The list for the shop.

The weekly plan produces a shopping list. Identical ingredients are combined and sorted by aisle, from fruit and vegetables through chilled goods and cheese to oils, sauces and spices.

Whatever is in the cupboard anyway you tick off once and it disappears from the list. For every dish it also says how long it keeps and whether it can be frozen.

04 Household and groups

Two adults are not twice the amount.

Anyone who does not eat alone sets up a household. KernBite adds the actual daily requirements together and cooks accordingly. The source code carries the example: 2159 kilocalories and 1600 kilocalories give a quantity factor of 1.74 instead of 2.0.

Everyone in the household swipes the same recipes. The shared cookbook then shows what everybody likes and what only some do. Anyone who wants to compete sets up a challenge and enters weight, training, steps and wellbeing. There are no prizes and no entry fees.

Millet bake with broccoli, plated — **Millet Bake with Broccoli**504 kcal, 26 g protein. Lunch, suitable for batch cooking. AI

The app

This is what it looks like

No mock-up and no draft. Every picture is a screenshot of the running app: the upper four from a phone, the lower two from a device in landscape.

The swipe screen of KernBite: a recipe photo fills the card, below it are calories, protein, carbohydrates and fat — **Swiping** Recipe card with photo and nutritional values. Right means keep it, left means not today.

The recipe list of KernBite: a search field and a filter button above a table of recipe name, meal and the values for calories, protein, carbohydrates and fat — **Searching** All 1,014 recipes, filterable by meal, cuisine and batch cooking.

The weekly plan of KernBite with the meals of one day and the daily targets reached — **Planning** The day as a plan, and from it the shopping list sorted by aisle.

Calculating Body data in, daily requirement out. Every step can be read back.

The recipe list of KernBite on a large screen, with the filters side by side instead of one below the other — **On tablet and Chromebook** More width means more overview: the filters sit side by side, the list shows more rows.

The leaderboard of a challenge on a large screen, with charts and the overall score below one another — **The challenge on the big screen** Charts and overall score without scrolling, handy in the kitchen.

Every picture on this page is a real screenshot, not a mock-up. The recipe photos within them are AI-generated illustrative images; the app attaches this note to every single picture, and here it stands as well.

The calculation

Calculated openly, without a language model.

Your daily target comes about in four steps. Each of them is a fixed formula, not an estimate and not a recommendation out of a cloud.

No language model takes part in the calculation. The same inputs always give the same result.

The app does not flatter. If the result comes out very low, or the pace is too fast, a clear warning appears instead of quietly nudging the number upwards.

01Basal metabolic rateIf an InBody scan is available, the measured value counts. Otherwise the app calculates by Mifflin-St Jeor from age, height, weight and sex.
02Everyday lifeTimes an activity factor, depending on how much you move outside of sport.
03SportEntered as calories per week and spread evenly over seven days.
That gives the maintenance requirement.
04DeficitFor weight loss the app calculates with 7,000 calories per kilogram of body fat, spread over the chosen period.
That gives your daily target.

Where we stand

What is missing, is missing on purpose.

WerbungKeine Banner, kein Sponsoring, keine Affiliate-Links, keine bezahlten Produktempfehlungen im Rezept.

TrackingKeine Analysewerkzeuge, keine Werbepixel, kein Fingerprinting, kein Profiling. Die Server stehen in Nürnberg, eine Übermittlung in ein Drittland findet nicht statt.

These three points are written exactly that way in the Terms of Use and in the Privacy Policy.

Who is behind it

Behind KernBite stands a private individual, Jose Daniel Encarnacao from Ketsch, who runs the project alongside a job. The app, the recipes and the calculations are protected by copyright; third-party components in use are subject to their own terms.

That has a flip side, and it should be stated openly here. Operation depends on one person's spare time. There is no hotline and no guaranteed availability. Questions go to kontakt@kernbite.de and are answered as soon as time allows.

Worth knowing

From the age of 16. Between 16 and 18 only with the consent of a parent or guardian.
It keeps running without a network. Entries stay on the device and go to the server as soon as there is a connection again.
Visible to others are the user name, group membership and the values shared in a challenge. Within a household, members additionally see each other's likes and dislikes.
No claim to permanence. Recipes may be added and may fall away; a particular set of features is not guaranteed.

Health notice

KernBite is not a medical device. Nutritional values are averages and vary with the product and the preparation; the calculation replaces neither a medical assessment nor dietary counselling. With pre-existing conditions, during pregnancy and breastfeeding, or after an eating disorder, professional advice comes before the app.

Challenge

Together it is easier

Resolutions rarely hold on their own. In KernBite you set up a group, share a six-digit code, and whoever has it joins in. After that half a minute a day is enough: check in, done.

You decide what it is about

A challenge has a name, a period and the goals you pick. Steps, training, weight, calories, protein, wellbeing. Anyone who does not want to talk about weight leaves it out of the scoring.

Points per category

Every category is scored on its own, and there is an overall score for the group. That way the same person does not always win, and whoever trails on weight can lead on steps.

Steps come from the watch

Anyone using a Garmin or Health Connect pulls the steps in with one tap instead of typing them. Without a watch you enter them by hand, which counts just the same.

You decide what becomes visible

Under „What I share“ you hide individual values from the group. Your weight then stays your business, while steps and training keep counting. Nothing is preset that you have not released yourself.

The leaderboard of a KernBite challenge with six categories and a bar chart of the group points — **Leaderboard** Points per category and for the group as a whole, week by week.

The daily check-in in KernBite with fields for weight, calorie target, protein target, training, steps and motivation — **Check-in** Weight, steps, training, motivation, energy and hunger. Takes half a minute.

The member list of a KernBite group — **Members** Who is taking part, who administers, and what each person shares.

One note we consider more important than any promise: values that were visible to the group during a running challenge cannot be taken back out of anyone's head afterwards. On the server they are deleted along with your account; with the other members they were visible beforehand. So think first about what you release.
