About this app
One photo. Done. Jausn recognizes what's on your plate and calculates the calories and nutritional values—in seconds, without scales or typing.
Jausn is a weight-loss app from Austria. For people who want to know what they're eating but don't want to weigh every meal.
WHY JAUSN EXISTS
I created Jausn because the existing apps didn't convince me. Knowing roughly what you're eating is better than knowing nothing at all—but that wasn't enough for me. I wanted to know exactly, without having to weigh and calculate every day.
So I tested and refined the AI model against reference data until the result was accurate: With over 2,000 images and embedded lab data, Jausn achieves an average accuracy of 92–96%.
With a single photo, in just a few seconds.
WHAT JAUSN CAN DO
• TAKE A PHOTO INSTEAD OF TYPING
Take a picture, and you're done. Calories, protein, carbohydrates, fat, and more.
• SCAN BARCODE
For all packaged items on the shelf.
• YOUR DAILY BUDGET
You can see what's still possible today. Steps and workouts from
Apple Health are automatically included.
• TARGET WEIGHT AND PROGRESS
Set a goal, see your progress. It's the week that counts, not the
individual day.
• WEEKLY REPORT
What went well—and what's not working.
• ADJUST QUANTITIES
Portions and estimated weight can be adjusted at any time.
WHY "JAUSN"
Because the app is made in Austria and intended for Austria. The breakfast-lunch-dinner rhythm is consistent, the snack is a separate meal, and the tone reflects the way people talk here. Going one day over doesn't change anything—Jausn tells you that, too.
Jausn is for general information purposes only and does not replace medical or nutritional advice.
