BOSTON, Dec. 02, 2021 (GLOBE NEWSWIRE) — Health tech company Lumme Health has just released the world’s first smartwatch app to automate calorie tracking — an activity that typically requires looking up the calorie values of individual foods. The kCalculator machine learning smartwatch app allows users to train their Apple Watch to passively count their bites and scientifically measure energy intake.

Similar to other apps that use motion sensor data to detect a particular activity, the kCalculator senses when a user is eating from the motions of the dominant hand and sends corresponding “eating detection” notifications for the user to verify on their phone or Apple Watch. A single “Meal Diary” screen on the phone app displays a running tally of the day’s calories along with the time, duration, pace and calorie estimates of each eating session.  Users are free to eat normally using utensils or their hands, and any eating that lasts for at least a few minutes can be detected.

“The #1 question we get is how the app knows what you’re eating,” says Lumme Health co-founder and CEO Arun Mathur. “The question itself speaks to the painstaking nature of traditional calorie counting. What you eat will always matter to good health, but the math on calories depends a lot on portion sizes — something that tends to get vastly underestimated.  But, it’s something we objectively measure pretty well in the form of a bite. By solving for volume first, adjusting for what you eat is surprisingly simple and effective.”

Lumme’s co-founder and Chief Behavioral Scientist J. Graham Thomas, Ph.D., who brings over 15 years of hands-on clinical research experience in psychiatry and obesity medicine, says, “Journaling everything we eat to achieve a calorie goal can be a tedious chore that, too often, uses up energy that could be directed towards mastering the actual habits that matter to long-term success. For the first time, Lumme’s technology removes a critical area of friction in weight management, which paves the way for more effective goal setting, progress tracking and problem solving. Calorie tracking scratches the surface.”

The kCalculator is a slice of the company’s forthcoming behavioral app for weight loss, which provides actionable insights, daily predictions and real-time interventions to help users achieve their goals and avoid cycles of problematic behavior.

The kCalculator A.I. Calorie Counter for Apple Watch (Series 4/5/6/7/SE) is available as a FREE download on the App Store for a limited time. For more information, visit
