About

BetterRunning App

BetterRunning is an AI running coach for iPhone and Apple Watch. It doesn't hand you a generic 12-week plan — it builds one around your body, and adjusts it every morning based on how you actually slept, how your heart is recovering, how much you've trained, and how the weather looks for today's session. HOW IT WORKS When you set a goal — a 5K, 10K, half marathon, or just getting fitter — BetterRunning reads your recent runs, last night's sleep, your heart-rate variability and resting heart rate, and your weekly volume from Apple Health. Your AI coach turns that into a multi-week plan, sized for you. Every morning, before you lace up, BetterRunning reads back from Apple Health: - HRV (heart rate variability) — your nervous system's readiness signal - Sleep — duration and stages from your watch - Resting heart rate and recent training load - Today's weather, the moment you open the app Those inputs become a readiness score, a short explanation in plain language, and — if needed — an adjusted version of today's session. If your HRV is suppressed and you slept poorly, tomorrow's tempo run becomes today's easy 25 minutes. If you're firing on all cylinders, the coach tells you to go. WHAT MAKES IT DIFFERENT Most running apps adapt after your run. BetterRunning adapts BEFORE it. EVERY WORKOUT COUNTS Your body doesn't know which workouts were runs. A long ride, a swim or a strength session counts towards your training load and your readiness, and Progress shows each week split between running and other training — so a jump after a big ride explains itself. AFTER EACH RUN The app celebrates your good ones from your real performance — not vague benchmarks. The AI gives specific feedback referencing your actual numbers. A COACH THAT LISTENS - Tell your coach "I'm travelling next week" or "make it easier this block" and get back a clean, confirmed change to your remaining sessions. It remembers why. - Edit a session your coach softened and it acknowledges your choice. - Cycle-aware coaching, opt-in. The phase is worked out on your phone; your dates and flow data never leave it. - Race time projections for every distance, refreshed daily as your fitness changes. ON THE WATCH Start a tracked run from your wrist. Live pace, heart rate, distance. Interval mode shows the rep you're in and the recovery left. Distinct haptics for every kilometre. Workouts, GPS routes and energy save into Apple Health as first-party data. HELP IS IN THE APP Profile → Help & support: a searchable FAQ, how-to guides and a contact form. No browser needed. IN YOUR LANGUAGE English, Dutch, German, French and Spanish — on the phone and on the watch. PRIVACY AND TRUST No account, no third-party analytics, no trackers, no ads. The only time we receive your email address is if you write to us from Help & support. Your plan and history sync through your own iCloud Private Database — only you can read it. Coaching requests go to a server we operate, which passes them to an AI provider to write your advice. Raw heart-rate, HRV and sleep data and GPS routes never leave your devices: the coach gets summaries and aggregates, never your location. Free one-month trial. After that, monthly or annual. Cancel any time. Requires iPhone running iOS 17.6+. Apple Watch (Series 5 or later) running watchOS 10.6+ recommended for live workout tracking.
