About
Tired of logging every bite? Calk is a calorie counter that helps you manage your weight without keeping a food diary forever. It suggests ingredient swaps for the meals you already eat. As the changes become part of your routine, you can stop logging every meal.
Your food and weight diary is free, with no ads. It's stored on your device and works offline after setup.
HOW IT WORKS
1. Log your food and weight for about a month.
2. Calk shows you what to swap in your own meals.
3. Try the swaps until they become second nature.
4. Keep tracking your weight without logging every meal.
If your eating habits or weight change, return to the diary. Your entries are still there. Calk sends a quiet notification if your weight trend persistently drifts off course.
START WITH THE FOOD ON YOUR PLATE
At home or eating out, choose a dish and adjust its ingredients, cooking method and portion to match what's on your plate. Include the oil and sauce, too — a photo won't tell you how much was used. Calk recalculates calories, protein, fat and carbs.
No need to build a recipe from scratch, weigh every raw ingredient or search through dozens of similar entries.
WEIGH IT, SAVE IT, THEN EYEBALL IT
Weigh your cooked portion the first few times and tap the heart button to remember the mix. Next time the dish opens the same way — just adjust the portion by eye. You don't need a kitchen scale at every meal.
YOUR CALORIE TARGET ADJUSTS AUTOMATICALLY
Sticking to your plan but the scale won't budge? While you're logging, Calk compares your food intake with your weight changes each week and recalculates your calorie target. Walking and workouts are reflected in your overall energy use. You don't need to add back the calories your watch says you burned.
SET YOUR OWN TARGETS AND LIMITS
Set targets for calories, protein, fat, fiber and water, and limits for added sugar and salt. Calk never changes targets or limits you set yourself.
WHAT TO CHANGE IN YOUR USUAL MEALS
Your personal report shows which dishes add more calories to your day and suggests ingredient swaps. You'll also see which habits keep coming up.
VARIETY IN YOUR DIET
The variety map shows the vegetables, fruit, beans, grains and nuts in your diet. It also counts how many different plants you eat each week and month.
FIBER, SUGAR, SALT AND MORE
Track calories, protein, fat, carbs, fiber, water, added sugar, salt, different types of fat and glycemic load. See how much fruit and vegetables you eat, too. Your report also covers vitamins, minerals and omega-3.
