Whistle is an AI training planner for running, cycling, swimming, strength work, and everything in between. Build a plan around your goals, adapt it when life changes, and understand what your training is doing over time. Plan with a coach that understands your week Ask Whistle to build a training week, create a longer program, adjust a workout, review your progress, or explain what your body is telling you. Your coach can use your goals, schedule, recent workouts, recovery, sleep, vitals, and local weather to help you make better training decisions. Training programs, not just single workouts Start a guided setup, tell Whistle what you are training for, and get a structured program you can follow week by week. Already following a plan? Bring that structure into Whistle and let your coach help you keep it organized. Workout planning that stays flexible Plan workouts for today, the week ahead, or a longer training block. Create structured sessions with warmups, intervals, targets, cooldowns, and activity-specific goals. Save workouts as templates so repeated sessions are ready when you need them. Train with better context Whistle turns workout and health data into practical planning support: - Training load to understand how much work you are absorbing - Projected load to see how planned workouts may shape your week - Recovery, sleep, and vital trends for daily context - Workout predictions for distance, duration, calories, and load - Training insights, heatmaps, and streaks to review consistency over time - Weather-aware planning with multi-day forecasts for outdoor sessions Apple Watch ready Send planned workouts to Apple Watch and start them from your wrist. Whistle also works with Apple’s Workout app experience, so your sessions fit into the tools you already use. Works with Apple Health (HealthKit) When you choose to share Apple Health data, Whistle can use workouts, activity, heart rate, recovery, sleep, and vitals to make planning and coaching more personal. The goal is useful training insight, not medical advice. Built privacy-first No account is required. Your workout and health data are handled with care, stored locally and in your personal iCloud where possible, and used only to power the features you choose. When AI processing is needed, Whistle uses the data required for the task instead of building a long-term personal profile on our servers. Some features require Pro or Ultra. Health, weather, watch, and AI features depend on device capabilities, permissions, region, and data availability.
