BetterRunning

BetterRunning is an AI-powered running coach for iPhone and Apple Watch. It creates personalised training plans, adapts them every day based on how the runner’s body is doing, and explains the reasoning behind each coaching decision. The app is built around a simple idea: most running plans are too static. They are written before the runner knows how they slept, how recovered they are, whether their HRV dropped, or how much training load they are carrying. BetterRunning uses Apple Health and Apple Watch data to make the plan respond to the runner’s actual readiness instead of forcing them through a fixed spreadsheet. A runner can use BetterRunning to train for goals such as a 5K, 10K, half marathon, marathon, or general fitness. The app generates a full structured plan based on the runner’s goal, current fitness, available training days, heart-rate profile, and target date. Plans are built with normal endurance-training logic: base, build, peak, and taper phases; long runs at the end of the training week; recovery weeks; no hard sessions on consecutive days; and controlled volume progression. Every morning, BetterRunning calculates a Readiness Score from HRV, sleep, and training load. This score determines whether the day’s session should stay as planned, be reduced, or be replaced with an easier recovery run or rest. The app does not just change the workout silently: it gives daily coaching text that explains what changed and why. That turns the product from a plan generator into a coach that helps the runner understand their body. The iPhone app includes a daily dashboard with coaching, readiness, the planned session, and a short lookahead. The plan view shows the full training calendar and detailed session instructions. The progress view tracks fitness signals such as VO₂ Max trend, weekly volume, and race-time prognosis. After a workout, BetterRunning gives post-run feedback on what went well and what to adjust next time, including feedback for free runs that were not part of the plan. The Apple Watch companion is central to the experience. It shows the planned session, guides the runner through workouts segment by segment, displays live heart-rate zone information, records runs to HealthKit, and syncs session state back to the iPhone. The goal is that the runner can follow the coach on the wrist without needing extra hardware. Privacy is a major part of the product. BetterRunning works with data already collected through Apple Health and Apple Watch. Health data is stored locally and in the user’s private iCloud database. No account is required for the core experience, Sign in with Apple is optional, and raw biometric samples are not sent to the AI service. The AI receives aggregated metrics only, such as readiness inputs and training context. The positioning is: BetterRunning is not a social network like Strava and not just a static training-plan app. It is a private, Apple-native AI running coach that listens to the runner’s body. It is made for recreational runners who want structure, clarity, and adaptive coaching without hiring a personal coach or buying new hardware.
