Base Layer is a fitness coaching app that builds your training program from real health data — heart rate, HRV, sleep, workout history — and adapts every week. Tell your coach what you're training for. A ski trip, a marathon, keeping up with your kids, or just getting stronger. Connect Apple Health, and Base Layer builds a periodized program that actually responds to how your body is recovering. HOW IT WORKS - Set your goals: Pick your sports, set target events, describe your constraints and schedule. - Connect your data: Base Layer reads Apple Health — heart rate, HRV, sleep, VO2 Max, workout history — so you never have to manually log anything. - Get your program: Your AI coach builds a multi-week roadmap with progressive overload, deload weeks, and event-specific peaking. - Train and adapt: Each week, your coach reviews your real recovery data and adjusts intensity, volume, and focus. Skip a week? Get sick? It recalibrates. WHAT MAKES IT DIFFERENT Your coach actually reads your data. Not just step counts — real training signals. Heart rate variability, resting heart rate trends, sleep quality, workout intensity. The program responds to what your body is telling it. One program, everything you do.
