The calorie counter you don't have to live in
Use one month to understand your food. Then step back: follow your weight trend and return to food logging only when something changes.
One year, not an endless diary
One focused month. Then mostly life.
Use an ordinary month to understand your food. After that, watch the weight trend and return to logging briefly when something changes.
- 1 focused monthUnderstand your usual meals
- Most of the yearLive normally. Watch the trend.
- Short checkupsOnly when something changes

Build it once — two taps from then on
A meal template is a familiar dish broken into the few decisions that change it. Pick the template on the home screen and tap “Eat” when everything is as usual. Pesto instead of tomato sauce on today’s pizza? Change only the sauce; the crust, cheese, toppings and portion stay in place while the whole meal recalculates.
Below is a simplified example of the Calk interface.
Where do the numbers come from? Calk combines official food tables, specialist publications, product labels and recipe checks into one checked food catalog. See how Calk builds and checks its food data.
What your diary says about your food
After at least 20 complete food-log days and 10 days of weight data in one 30-day window, Calk can read the ingredients and cooking choices behind the totals. The report turns the month into four practical views:
- Your nutrition at a glance. Calories, macros, vitamins, minerals, variety and the main takeaway from the month.
- How varied your food really is. Food groups, plant variety and the easiest gaps to fill.
- Which foods are more filling. How calorie density, protein, fiber and water shape estimated fullness.
- What you can change. The clearest gaps and familiar foods that may help close them.
