If you run, lift, ride, or train for anything and you're on a GLP-1 like Ozempic, Mounjaro, or Wegovy, most fitness apps don't understand what your body is doing. They were built before GLP-1s changed the game. Ready Trainer One starts from your reality: your dose schedule, your training load, your recovery, your appetite, your sleep — all pulled directly from Apple Health. RTO gives you insights, not shame, judgment, or criticism. Your data tells a story about your health and your training. RTO helps you read it. WHAT IT DOES • Reads your Apple Health data: workouts, sleep, HRV, resting heart rate, weight, food, medications and supplements. • Surfaces real patterns. Did your readiness drop after your last dose? Did under-fueling on travel days cost you yesterday's workout? You get answers backed by your own data, not vibes. • Daily Brief: a short, honest morning read on where you are and what to watch for today. • Today screen: dose schedule, readiness, training load, sleep at a glance. • Chat with an AI coach that knows your data. Ask anything about your last week, your training, your meds, your weight. Get answers grounded in what actually happened, not generic advice. • Log food with text or a photo. Track doses, side effects, hydration. • Insights: charts, correlations, and pattern interpretation that explain what your data means. WHAT IT ISN'T • Not a diagnostic tool. Not medical advice. Not a substitute for your trainer, your doctor, or your prescriber. • Not a tracker that ignores your medication. Your GLP-1 schedule shapes everything else, and Ready Trainer One treats it that way. • Not a shame engine. No streaks, no judgment, no "should-haves." PRIVACY & AI DATA USE • Apple Health data stays on your device unless you choose an AI-powered feature that needs bounded context to answer. • AI coaching currently uses Anthropic. Signed-in users route requests through readytrainerone.com before Anthropic; Bring-Your-Own-Key users send requests from their device directly to Anthropic. • We do not intentionally send your name, email, Apple ID, or Ready Trainer One account identifier to Anthropic. Your messages, selected photos, and health context may still contain personal information. • We do not sell your data or use it for advertising, marketing, or cross-app tracking. • Anthropic's API terms say Customer Content is not used to train Anthropic models. • You can turn AI data sharing off in Settings. Manual logging, Apple Health reads, and non-AI features still work. PRICING • Free: daily dashboard, manual logging, charts, correlations, dose tracking, and limited AI coaching/photo food parsing. • Pro ($3.99/month or $29.99/year): higher AI limits, AI-narrated Daily Brief, AI interpretation of your patterns, deeper memory, and more photo food parsing. • Bring your own Anthropic API key: power users can use their own key in Settings. No AI usage charges from us. Terms of Use (EULA): https://readytrainerone.com/terms Privacy Policy: https://readytrainerone.com/privacy
