Xaki - Gut Health & Fitness

Your biggest barrier to progress isn't your fitness routine. It's your gut. Xaki helps you track and provides guidance to keep you moving forward.

Your biggest barrier to progress isn't your fitness routine. It's the patterns you can't see.

Xaki brings your training, nutrition, digestion, sleep, pain, and vitals into one place. Instead of bouncing between apps that never talk to each other, you get Kai, a personal fitness companion that finds the connections across everything you track and gives you ranked, actionable recommendations.

Not a substitute for professional medical advice, diagnosis, or treatment. Always consult a qualified healthcare provider for medical concerns.

PATTERNS, NOT JUST DATA

Most trackers give you charts. Kai gives you insight. Gut issues that flare after heavy training weeks with low-fiber meals and short sleep? A protein gap on exercise days that's dragging your recovery? Kai finds these multi-factor patterns and explains them in plain language, with clear next steps ranked by impact.

LOG EVERYTHING IN SECONDS

• Workouts: Sets, reps, and weight with muscle group tracking. Bodyweight exercises supported. Save workouts as reusable programs.
• Meals: Describe what you ate and Kai estimates macros instantly. Evidence-based calorie and protein targets adjust to your goals. Plan meals ahead with the built-in meal planner.
• Digestion: Bristol scale tracking with comfort and urgency ratings.
• Pain and injuries: Log type, location, and intensity. Track what aggravates or improves them over time.
• Blood work: Enter lab values and monitor biomarkers across tests.
• Water: Quick-tap hydration tracking.

SYNCS WITH APPLE HEALTH

Sleep, heart rate, steps, weight, and active energy sync automatically. These feed directly into Kai's analysis so you never have to enter them manually.

WORKS WITH YOUR GEAR

Apple Watch, Garmin, and MyFitnessPal data flows in through Apple Health. Your existing tracking setup gets smarter, not replaced.

AI THAT EARNS YOUR TRUST

Kai stays silent when there's nothing meaningful to say. When it speaks, every insight is grounded in your data, with observed patterns, ranked hypotheses, and recommendations split into what to try now and what to follow up on. You give feedback on every insight and Kai learns from it.

BUILT FOR PRIVACY

Your health data is yours. Xaki does not sell or share it with advertisers. Data is encrypted in transit and at rest. You can delete your account and all data from the app at any time.
