NATIONWIDE - JANUARY 2026 - (USAnews.com) In the world of health and fitness apps, the most significant barrier to long-term success is often the same: users abandon calorie-tracking apps within the first two weeks. For many, the process of manually logging every meal feels tedious, time-consuming, and error-prone. But what if there were a solution to this problem that made tracking nutrition as simple as snapping a photo? This is exactly what Cal33, the innovative nutrition tracking app, offers.
Founded by Nemanja Divjak, a serial entrepreneur with over 25 years of experience in the tech industry, Cal33 is the culmination of his years of expertise in mobile app development and user engagement. Divjak, known for his success in creating over 200 mobile games that have collectively reached more than 120 million players worldwide, has brought a fresh perspective to the health and fitness space. Instead of building another calorie-tracking app using traditional databases and manual entry, Divjak applied his deep understanding of user experience to solve one of the health industry’s most persistent issues: friction in nutrition tracking.
A Vision Beyond the Status Quo
Before Cal33, the calorie tracking landscape was filled with apps that required users to painstakingly search through food databases or weigh their portions before entering them. This process often led to frustration, especially for users who were busy or simply wanted an easy, quick way to log their meals. "Most people don't quit tracking calories because they lose motivation, they quit because the apps make it feel like data entry," says Divjak. "I’ve spent 25 years building apps that 120 million people chose to open every day. Cal33 applies that same obsession with user experience to nutrition. If logging a meal takes more than 5 seconds, we've failed."
The breakthrough for Cal33 came with the integration of AI-powered food recognition. Instead of typing in every ingredient or scanning through lengthy databases, users simply take a photo of their meal, and the app uses artificial intelligence to instantly identify the food and provide accurate nutritional information, including macros like protein, carbohydrates, and fats. This AI-first approach allows for frictionless meal logging and a far more user-friendly experience than traditional methods.
AI Food Recognition: The Core Innovation
What sets Cal33 apart from competitors like MyFitnessPal or Lose It is its core reliance on AI, rather than treating AI as a secondary or add-on feature. "Other apps treat AI like a checkbox feature. We built Cal33 around it," Divjak explains. "Point your camera at lunch, and you're done. No searching, no scrolling through databases, no guessing portion sizes. The AI handles it."
This unique feature is designed to make calorie tracking as simple and seamless as possible. The app's AI scans the meal in real-time and automatically logs the nutrition details, allowing users to stay on track with their health and fitness goals without the usual hassle. Whether users want to lose weight, build muscle, or simply eat healthier, Cal33 makes it easier than ever to achieve those goals.
User-Centered Design: Gaming Principles Applied to Nutrition
While most health and fitness apps are designed by companies with backgrounds in wellness or medicine, Divjak brings a completely different perspective to Cal33. His experience in mobile game development has shaped the app’s design to be not only functional but also engaging. In mobile games, the key to success is user retention, and the same principles that made his games addictive and fun are applied to Cal33. This includes intuitive interfaces, satisfying feedback loops, and frictionless interactions.
"In gaming, you learn very quickly what makes people come back tomorrow. It’s not about flashy features, it’s about removing every point of friction and making the core experience satisfying," Divjak says. "Health apps have ignored this for years. Cal33 doesn't."
The result is an app that feels less like a chore and more like a tool users want to use every day. It’s a solution that makes tracking calories not just possible but enjoyable.
Simplified Tracking: The Anti-Bloat Approach
Another area where Cal33 distinguishes itself is in its simplicity. While other calorie trackers have become increasingly cluttered with social features, premium paywalls, and endless menu options, Cal33 strips nutrition tracking back to what really matters: snapping a photo, seeing your macros, and tracking your progress. There are no distractions, no unnecessary complexity, just a clean, user-focused experience that helps users achieve their health goals without any friction.
This minimalist approach is one of the reasons why Cal33 has already gained traction among users. It takes the core functionality of calorie tracking and maximizes it with AI, while leaving out the unnecessary extras that often overwhelm users. It's an app designed for real people with real health goals, offering the exact tools they need to succeed without the clutter.
Privacy First: Data You Control
In an era where personal data is often commoditized by many fitness and health apps, Cal33 takes a different stance. "Your nutrition data is personal. We don't sell it, we don't share it, and we don't guilt you into posting your meals on social media," Divjak assures. Cal33 prioritizes privacy, ensuring that user data is secure and never shared with third parties. Users can track their nutrition, set goals, and monitor progress without worrying about their personal information being sold or exploited.
Cal33’s Path to the Future
As part of the larger "33" family of AI-powered tools, Cal33 benefits from ongoing investment in cutting-edge AI capabilities. The app is continually evolving, with a roadmap focused on expanding its features and enhancing the AI to make nutrition tracking even more intuitive and personalized. Alongside Cal33, Divjak’s company, Nitrotech, is also developing Flow33, an AI tool focused on content generation, which hints at an even more interconnected future for the "33" ecosystem.
With an already strong track record in mobile app development, Cal33 is poised for continued success. Divjak’s expertise in user acquisition and performance marketing, gained through years of work with top platforms like Google Ads, Facebook, and Unity Ads, ensures that the app is positioned for rapid growth. His ability to reach health-conscious consumers on a large scale is a key factor in Cal33’s bright future.
