Faster Stronger

Faster Stronger is an AI health coach built on top of your Apple Health data. Most fitness apps show you numbers. Faster Stronger reads your steps, sleep, heart rate, workouts, and 18 months of history — and then explains what's happening, why, and what to do about it. Every insight is grounded in your actual data, so the advice is specific to you, not a generic article. WHAT YOU GET WITH PRO • Daily coaching: a personalized note every time you open the app, anchored to today's progress and recent trends. Time-aware — different in the morning vs. the evening. • Sleep night reflection: not just hours, but how the night went. Heart-rate calmness, time to settle, mid-night spikes, anything unusual. • Weekly long-form story: a deep narrative of your last 18 months — phases, drivers, what's coming next, three projected scenarios. • Cross-metric drivers: how your sleep, training, and recovery actually move each other. Mechanisms, not correlations. • Quick check-ins: the coach asks short follow-up questions about anomalies, plans, mood. Your answers feed back into next runs. • Adaptive experimentation: each week the coach tests a coaching hypothesis and reports back on what worked. WHAT YOU GET FOR FREE • Charts and trends across 18 months • Today's progress with weekday-aware pacing • Resting and active hour patterns • Workout and sleep cards • Notification reminders PRIVACY Your health data stays on your device. When AI runs, only the data needed for the prompt is transmitted to your selected AI provider for the duration of the request. No accounts, no logins, no tracking.
