Kitty
Reach your goal weight. Kitty does the counting.
Snap a photo, scan a barcode or just say what you ate. Kitty works out calories and macros in seconds, suggests meals that fit the rest of your day and cheers you on, every single day.
For iPhone, in English and German.
Counting calories shouldn't feel like homework.
Most people don't quit because they lack willpower. They quit because tracking is tedious and makes them feel bad. Kitty fixes both.
Counting on your own
- Weighing every gram on a kitchen scale
- Scrolling through 40 versions of “banana”
- Guessing what's in a restaurant meal
- Feeling judged the moment you go over
- Giving up in week two
Counting with Kitty
- Snap a photo and get calories and macros in seconds
- Scan a barcode or simply say what you ate
- Kitty splits your plate into its parts and estimates each one
- A friend who stays kind on messy days, too
- A streak and a trend that keep you coming back
Log a meal in the time it takes to take a photo.
Three ways to log. Pick whatever is quickest in the moment.
-
Snap a photo
Kitty spots every part of your plate (eggs, pasta, sauce, bread) and estimates each portion. On iPhone Pro models, the LiDAR sensor helps measure how much is really there.
-
Scan a barcode
Packaged food? Point your camera at the barcode and Kitty fills in the values from the product data.
-
Just say it
“Two eggs and a slice of toast.” Kitty turns what you say into entries, no typing needed.
The AI recognizes your food. The numbers come from nutrition databases such as BLS, USDA and Open Food Facts, and you can adjust every amount before you log it.
Not sure what to eat? Ask Kitty.
Kitty knows what's left of your day: calories, protein and the foods you love. Ask for an idea and get meals that fit, with simple steps and links to real recipes on the web.
- Ideas that fit your remaining calories and protein
- Recipe steps from Kitty, plus real recipes from the web
- Log any idea with one tap
See how far you've come.
Every logged day earns a paw print. Your week and your weight trend show the progress the mirror can't show yet, even when the scale has a bad day.
- Streaks that turn logging into a habit
- Your week of calories at a glance
- A weight trend that leads to your goal

Yesterday you ate 300 kcal over your goal.
Okay, big day! 🎉 Tomorrow we go again. You've logged 12 days in a row, that's huge!
That's completely okay. One day doesn't undo your progress. I'm proud you logged it 💕
300 kcal over. No problem: a lighter dinner tomorrow and your week is right on track.

How much does Kitty cost?
Kitty is a subscription. You'll see the exact price, and whether there's a free trial, in the app before you pay. Payment and cancellation run through your Apple ID.
How accurate is the photo scan?
Kitty identifies each part of your meal and estimates the amount. On iPhone Pro models, the LiDAR sensor helps measure the portion. The nutrition values come from food databases.
Like any estimate it can be off, so you can check and adjust every amount before you log it.
How does Kitty know my calorie goal?
When you set up the app, you answer a few questions about your age, height, weight, activity and goal. Kitty calculates your daily goal from that with the Mifflin-St Jeor equation and built-in safety limits. You can see the full calculation and its sources in the app.
Do I need a kitchen scale?
No. For most meals a photo or a portion size is enough. If you like weighing, you can enter exact grams.

Kitty is made for adults who want to lose a few kilos or eat more mindfully.
