The story behind Flexen
Flexen was born from a simple frustration: Why do you need 5 apps when one can do it all? Calorie counter here, workout planner there, sleep tracker over there — and none of them talk to each other. We wanted to change that.
Holistic health, accessible to everyone
Our vision: combine AI with health data so that everyone has access to a personal coach — not just those who can afford a trainer.
Living a holistically healthy life shouldn't require five different subscriptions. Flexen brings together nutrition, training, sleep, mental health and AI coaching in a single app. Personal. Intelligent. Affordable.
“Health is not a luxury. Everyone deserves a coach who knows their data, understands their goals, and is available around the clock.”
— The Flexen Team
What makes Flexen different
Three principles that guide everything we build.
AI as a coach, not a gimmick
Julio isn't a marketing feature. He has access to your data and can take real action: create plans, analyze progress, make recommendations. A real coach that keeps learning.
Holistic, not fragmented
Nutrition affects sleep. Sleep affects training. Training affects mood. Flexen understands these connections — because all your data lives in one place.
Your data belongs to you
Health data is the most personal data there is. We don't sell it, we don't share it, and we never will. Your data stays your data. Period.
The technology behind Flexen
Cutting-edge AI, seamlessly integrated into your daily life.
Computer vision for food recognition
Flexen's AI analyzes photos of your meals in real time. Over 10,000 foods are recognized — with calories, macros and portion sizes. No manual entry, no guessing.
LLM with function calling for Julio
Julio is more than a chatbot. Through function calling, he can actively access your data and take action: create workout plans, analyze meals, detect sleep patterns — all through natural language.
Health Connect & HealthKit integration
Flexen connects seamlessly with your smartphone's health ecosystem. Sleep, steps, heart rate — everything flows together automatically. No additional wearable needed.
