The Ketone Difference: We're the only app that connects the dots between fasting, nutrition, and training with real AI—not just timers and calorie counters.
The "No Sacrifice" Approach.
Most apps force you to starve. Ketone uses AI to align your eating windows with your circadian rhythm and nutrient needs. The result? You heal your metabolism and lose weight without the constant battle against hunger.
Wrist-Based Coaching
Control your Tabata intervals and check fasting status instantly from your Apple Watch.
Big Picture Planning
Use the iPad app to visualize your long-term progress and organize your weekly meals comfortably.
Seamless Sync
Start a workout on your Watch, log water on your iPhone, review stats on iPad. Everything stays in sync.
Turn your body into a fat-burning machine.
Ketone acts as the central gear that connects all aspects of your health. When your fasting, nutrition, and training work together, results happen automatically.
AI Meal Planner
Personalized menus that keep you satiated during your eating window.
HIIT & Tabata Tracker
Guided intervals specifically designed to accelerate ketosis.

Health Reclaimed
"Finally an app that doesn't make me feel like I'm starving. The AI meal planner actually understands my schedule."
"The Watch integration is game-changing. I can track my HIIT sessions without even looking at my phone."
"This isn't just another calorie counter. It's the only app that connects fasting, food, and fitness intelligently."
Why Ketone Actually Works
Most apps treat fasting, nutrition, and exercise as separate activities. We integrate them based on metabolic science.
Circadian Rhythm Alignment
Our AI schedules your eating windows to match your body's natural insulin sensitivity cycles, maximizing fat burning during fasting periods.
Metabolic Flexibility Training
HIIT and Tabata protocols timed with your fasting state accelerate ketone production and preserve muscle mass during weight loss.
Adaptive Nutrient Timing
Real-time analysis of your activity data (via HealthKit) adjusts your meal composition to prevent metabolic slowdown and maintain energy.
Evidence-Based Approach: Ketone's methodology is rooted in peer-reviewed research on intermittent fasting, ketogenic metabolism, and high-intensity interval training. We don't use gimmicks—just biology.
