Endure is a personal running coach that lives entirely on your iPhone — with no subscriptions, no new accounts, and no syncing to third-party platforms. It reads your workouts, heart rate, HRV, and sleep data directly from Apple Health, then highlights the coaching signals that truly matter: your recovery status, the type of run to do today, and whether your training is progressing correctly. — READINESS & TRAINING LOAD — Each day, Endure evaluates your readiness across four levels — Ready, Normal, Caution, Recover — using your HRV trend, resting heart rate, sleep, and recent training load. The Training tab displays your fitness (CTL), fatigue (ATL), and form (TSB): the same metrics used by elite endurance coaches, presented in a way that’s designed for regular runners, not data scientists. — DAILY TRAINING SUGGESTION — Endure's suggestion engine analyzes your recent workout pattern, weekly schedule, and current fitness trend to recommend exactly what you should do today: Rest, Easy, Steady, Tempo, or Long. It also explains its reasoning so you understand why, not just what. — RACE PREDICTOR & TRAINING PACES — Set a race goal with a target distance and finish time. Endure uses your actual PR data with the Riegel formula and VDOT system to predict your finish times across different distances and creates a personalized set of training paces: Easy, Steady, Tempo, Threshold, Interval, and Repetition. — TRENDS THAT MEAN SOMETHING — Three charts illustrate your season’s progress: an 8-week volume chart to monitor your load, a 12-month consistency chart to assess your routine, and a 12-week pace trend to confirm improvements. Each chart includes a simple, plain-English summary. — YOUR RUNS, FULLY ANALYZED — Every run displays pace zones, per-mile splits, HR timeline, elevation profile, and a route map with an optional heart rate zone overlay. You can also share a branded run card — with your route — directly from the run detail screen. — APPLE WATCH & HOME SCREEN WIDGET — Your weekly mileage ring and current streak are visible on your home screen and Apple Watch, updating automatically after each run. — YOUR DATA STAYS YOURS — Endure works with every run you've ever recorded on Apple Watch, iPhone, or any HealthKit-compatible device. Nothing is uploaded to any server. Ever.
