Finally understand what's working for your body—no guesswork, no gimmicks.
Key to Health is designed for high-achieving, busy people who want to look better, feel better, and optimize their long-term health without spending hours on complex routines.
Backed by science. Guided by AI. Built for real life.
Our breath sensor gives you real-time feedback on your body's fat metabolism—so you can see what your daily choices are actually doing, not just hope for the best. Pair that with smart AI coaching, and you have a system that adapts to you.
What you'll get:
• Real-time fat metabolism tracking with our breath acetone sensor
• Personalized coaching from Key, your AI health guide
• Clear, science-based goals and progress tracking
• Tools to build strength and support long-term health
• Eat what you love—no restricted foods, no keto required
Meet Key: Your 24/7 AI Coach
Key learns from your habits, adjusts your plan, and guides you every step of the way. Instant support and personalized guidance, whenever you need it.
Grounded in clinical evidence. In a published clinical trial, participants following the Key to Health program lost an average of 10% total body weight over 48 weeks.
No fad diets. No extreme routines. No forbidden foods. Just real progress, made easy.
This app and breath monitor are for adults 18 years and older.
