One skill at a time, with a weekly dose you can actually keep. No generic drills. No filler.

KronixAI is the AI health companion built for a longer, stronger life Most health apps track one thing. KronixAI tracks everything that matters — sleep, fitness, nutrition, and the lifestyle factors around them — and uses AI to reason across all of it at once. When your gym performance drops, KronixAI connects it to a week of short deep sleep and Monday's late, heavy dinner. Come back from a trip, and it works out how to fix your jet lag without derailing your training. Few apps are as personalized — or as attuned to your goals and schedule — as this. WHAT MAKES KRONIXAI DIFFERENT Longevity lens — every insight is framed through the science of biological aging: metabolic health, inflammation, cellular repair, mitochondrial function, hormonal balance. Centralized health data — one app for every pillar plus your injury state, and one AI that sees all of it. Cross-pillar intelligence — automatically explains how last night's sleep affected today's session, how your nutrition is slowing an injury's recovery, or how a big night out is showing up in your HRV. It remembers — your whole history is on tap ("what was I benching in April?", "how has my sleep trended this year?"), and it learns your personal baselines and patterns — like how travel affects your sleep — instead of judging you against population averages. Conversational by default — log data, ask questions, and get recommendations in plain language. Snap a photo of a meal and the macros are estimated for you. Daily scores and insights — wake up to a readiness score for today, a long-term trajectory score, and the single highest-impact thing to do — generated fresh each morning from your data. Visual dashboards — rich charts and trends for every pillar; watching your deep sleep, squat progression, or protein intake over time is core to the experience, right alongside the chat. Agentic — the AI doesn't just answer; it logs your data, edits entries, builds and saves training programs and meal plans, and takes action for you. WHAT IT TRACKS Sleep — stages, HRV, resting heart rate (via Apple Health) Fitness — per-set strength data, volume, and progression; Apple Watch workouts Nutrition — meals, macros, and meal timing Injury & resilience — injury sites, pain over time, and rehab/prehab consistency Body composition — weight, body fat, and muscle mass Life — activities, travel, illness, and factors like alcohol, stress, and cycle that affect the rest Built for wherever you're starting from — brand new to exercise, an experienced lifter optimizing, improving at a sport, fixing your sleep, or simply investing in a healthier future. KronixAI is powered by Claude, Anthropic's AI. Your health data is used solely to generate your insights and is never sold. Not a substitute for professional medical advice.
