MyFitnessPal Acquires Cal AI; 19-Year-Old Founder Zach Yadegari Launches Productivity Brand Flow
Zach Yadegari, 19, sold the AI-powered calorie-tracking app he cofounded in high school. The Miami-based founder has now launched a productivity brand called Flow.
MyFitnessPal acquired Cal AI, an AI-powered nutrition and calorie-tracking app, in December 2025. The app officially launched in May 2024 and grew to 10 million users while generating $30 million in annual revenue. Zach Yadegari, 19, cofounded Cal AI while still in high school.
He is based in Miami. Yadegari said the sale followed discussions among the founders about their individual priorities and goals. "it came down to us discussing everyone's priorities and goals in life.
That framework really helped us come to a consensus of what we all wanted," he told Business Insider. He added that the founders wanted Cal AI's legacy to continue while allowing him to pursue other work. "We want the legacy of Cal AI to live forever and continue to grow.
At the same time, my life's mission isn't building a calorie tracking app," Yadegari said. Before Cal AI, Yadegari sold his first app, Totally Science, for $100,000 at age 16. Totally Science is an unblocked website that lets students play games during school.
After the acquisition, Yadegari assembled a team for a new venture called Flow. Flow is a brand that intends to host a suite of products geared toward productivity and improving people's health. The first product, the Flow Alarm Clock, was released in March.
Customers must purchase a small, portable dock and download the Flow app. On the app, users set alarms and choose which apps to block. When the alarm sounds, they must physically get up and tap their phone on the dock to turn it off, which also unblocks the apps.
The Flow Alarm Clock also tracks users' sleep patterns and records sleep sounds. Yadegari said he wanted a physical product that would solve his own habit of scrolling on his phone for 30 minutes after waking. "I wanted to make something physical, but I didn't want it to take a year of research and development," he said.
Yadegari noted the challenges of manufacturing and shipping physical products. "The elephant in the room is that we have to ship physical products and manufacture them. We have to scale with the amount of supply that we carry, and that's tricky.
Shipping delays can also slow us down," he said. He said experience from running Cal AI gave him confidence to start again. He added that health, productivity, and wellness are his preferred categories because they affect people's lives directly.
