About Calkub

Calkub is an AI calorie tracker for iPhone, made for the food people actually eat in Thailand. It works fully in Thai, with English one tap away. Photograph a meal, scan a barcode or search a dish, and you get the calories, protein, carbs and fat.

Who makes Calkub

Calkub is run by Arctis Labs, which operates both the app and this website. Calkub has been on the App Store since October 2026. You can reach us at hello@calkub.app or through our support page.

Where the numbers come from

Calkub's food database holds 194 Thai dishes and 149 international dishes, each with a named source. Food that isn't in the database gets an AI estimate instead. When you scan a photo, the app shows the range the model estimated with the whole meal's total, and logs that total, or just your share when you split the meal.

Your daily calorie target starts from the Mifflin-St Jeor equation and how many times a week you work out, then adjusts for your goal and pace: the same formula in the app and in our daily calorie calculator.
