Marathon Coach vs Marafit

Marathon Coach™ — Train Smarter™ Set your goal once. Get an adaptive race training plan that appears in the native Apple Watch Workout app — no chat coach, no spreadsheets. THREE PILLARS • Glanceable — Open the app and see today’s workout instantly: distance, pace guidance, and your week at a glance. • Autonomous — Plans build and adapt from your real runs, sleep, heart rate, and training load. No typing to an AI chat coach. • Watch-native — Send your plan to Apple Watch. Workouts appear under Scheduled in the Workout app via WorkoutKit. HOW IT WORKS 1. Set your race goal, target time, and training level (~2 minutes). 2. Connect Apple Health (optional but recommended) for personalized adaptation. 3. Train where you are — Start outdoor runs on iPhone GPS from the app, or open plan sessions on Apple Watch under Workout → Scheduled. Lock the phone for Live Activity metrics while you run. 4. Weekly reviews and recovery signals adjust your plan as you train. FREE CORE The full core experience stays free: goal setup, adaptive plan, Apple Health, Apple Watch → Scheduled, outdoor iPhone GPS runs with Live Activity (time, distance, pace), weekly plan review when you open the app, and share cards. No account required for free use. MARATHON COACH PRO (OPTIONAL) Upgrade to Marathon Coach Pro for deeper coaching — daily plan tune-ups, recovery-aware adjustments after rough days, post key-workout reviews, background plan refresh when entitled, and post-run pace zone estimates on planned sessions (plan-anchored — not HR or medical zones). Subscribe in the app via Apple (auto-renewable). Manage or cancel anytime in Settings → Apple ID → Subscriptions. AI COACHING (OPTIONAL) Enable AI coaching in Settings for plan adjustments from summarized Health metrics — never raw GPS tracks. Or keep a local plan with zero server traffic. You can turn AI off anytime. SHARE YOUR PROGRESS Export branded share cards — race countdown, week in review, latest workout — as square or 9:16 Story images. REQUIREMENTS • iPhone (iOS 17+) • Paired Apple Watch (watchOS 10+) for scheduled Watch workouts • Not optimized for iPad in this version Training guidance only — not medical advice. Consult a physician before starting or changing any exercise program. Privacy: https://www.getmarathoncoach.com/privacy Support: https://www.getmarathoncoach.com/support

Marafit turns your own Apple Health running data into a full 16-week marathon plan — and keeps adjusting it to what you actually run. Most training apps hand you a template and ask you to fit into it. Marafit reads your last 90 days of runs, works out your heart-rate zones, your easy pace, your threshold pace and your current fitness, and builds the plan around those. WHAT YOU GET FOR FREE • A complete 16-week periodised plan — 3:1 build/down weeks, a 3-week taper, every session placed on a real date • Pick your own training days: long run day, quality day, and as many support runs as you want (3 to 6 sessions a week) • Personal heart-rate zones for every session, derived from your maximum and resting heart rate via the Karvonen method • Daily readiness score from HRV, resting heart rate and sleep, with the full breakdown of how it was calculated • Today's fitness, fatigue and form (CTL / ATL / TSB) • Weekly score: planned versus actual, session by session • Long-run comparison: heart-rate curve and time in each zone • A realism check on your goal time, so you find out before week one rather than on race day MARAFIT PRO • Paces tuned to you — easy and threshold paces come from your own measured efforts and VDOT, instead of being derived from your goal time • A plan that follows you — miss a week or overshoot one, and the remaining weeks are re-anchored to what you actually ran • Fitness and fatigue trends over 90 days, not just today's numbers • Deep run analysis — aerobic efficiency, heart-rate drift with warm-up removed, heat stress from the temperature and humidity recorded during the run, plus running dynamics and elevation HOW IT WORKS Marafit reads runs, heart rate, HRV, resting heart rate, VO2 max, sleep and body metrics from Apple Health. It never writes anything back. Every calculation runs on your iPhone. The training model follows established methods: Karvonen heart-rate reserve for zones, Daniels VDOT for equivalent performances and threshold pace, Banister TRIMP for training load, and the CTL / ATL / TSB fitness-fatigue model. BEFORE YOU START Marafit needs running history in Apple Health to build anything — record runs with Apple Watch or the iPhone Workout app. If you have none yet, tap "Or explore with demo data" on the first screen to load 13 weeks of sample runs and see the whole app, then clear them in one tap. Currently supports the full marathon (42.195 km). Half marathon is not included: the periodisation, long-run progression and race-pace work are all calibrated for the full distance, and offering a rescaled version would produce a plan that looks usable but isn't. iPhone only. There is no iCloud sync, so your data stays on the device you use. PRIVACY No account. No servers. No analytics, advertising or tracking SDKs. Your health data never leaves your device — we have no way to receive it even if we wanted to. Deleting the app deletes everything. SUBSCRIPTION Marafit Pro is available as a monthly or yearly auto-renewing subscription, or a one-time lifetime unlock. Eligible Apple IDs get a 7-day free trial on the yearly plan. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period; manage or cancel any time in your App Store account settings. The lifetime option does not renew.
