Kost & Kurs

Simple calorie tracking. Log a meal in under 30 seconds and get on with your day.

What it is

A calorie counter for iPhone. Tap, enter calories, done. Name and details are optional.

• Foods from Nordic and international databases (Frida, Livsmedelsdatabasen, USDA)
• A meal calculator that combines ingredients into saved meals
• Meal templates that can prefill your day, even with different templates for different weekdays
• Daily calorie targets, optional protein, carbs and fat, plus weekly and monthly stats

Intent

For people who want to be mindful about what they eat without making it a second job. No overwhelming food diary and no social features.

Your data stays on your device. No account is required, and there is no tracking and no ads. If you want to sync across devices you can create an account, but it is optional. The app is built for the Danish market first.
