EndureIndex vs Marafit

Ready to train — or is recovery the smarter choice today? EndureIndex helps you better understand your daily readiness and plan your training more consciously. The app uses data from Apple Health and turns it into clear signals for readiness, training load, recovery and endurance development. This helps you see more clearly whether your body is ready for training, whether light movement would be a better option, or whether you should give your recovery more space. What EndureIndex offers: • Readiness Score for your current daily condition • Endurance Score for your endurance development • Training load, recovery and trends at a glance • Analysis of HRV, resting heart rate, sleep, steps and workouts • Weather and environmental load, where available • Clear insights instead of raw data only • Goal focus for fitness, fat loss, weight maintenance, more energy, consistency and movement • Apple Watch app and widgets • Support for English and German Why EndureIndex? Not every day is the same. Sometimes your body is ready for an intense workout, sometimes light movement or recovery is the smarter choice. EndureIndex helps you better understand important signals from Apple Health and use them to make more conscious decisions about training and recovery.

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.
