PaceBrain vs Narelia

PaceBrain is an AI running coach. It writes your training plan, adapts it when life gets in the way, and tells you what your data actually means. Built for self-coached runners who want the thinking of a coach without the price of one. YOUR PLAN, WRITTEN AND ADAPTED • A full training plan built around your goal race, your history and your available days • Change it in plain English — "I'm away next week", "make Tuesday easier" — and the plan re-optimises around it • Going away? Set your dates and the plan reshapes itself, including a sensible ramp back • Send planned sessions straight to your Garmin or Wahoo device KNOW YOUR RACE TIME • Six prediction models combined and weighted to your training context • Always shown as a confidence range, never a single false-precision number • Race planner with pacing, splits and a weather read for the day • Post-race analysis of how you actually executed it A DAILY READ ON YOUR TRAINING • RunSignal: a straight answer on whether today is a push day or an easy one • Training load tracking that flags when you are ramping too fast • Heart rate zones, cadence, elevation and pace trends over time • Your Running DNA — the profile of what kind of runner you actually are FUEL IT PROPERLY • Nutrition and meal plans built around your training volume and preferences • Dietary preferences and foods to avoid respected throughout • Export to PDF or spreadsheet BRING YOUR OWN DATA • Sync with Garmin, Strava, Polar and Wahoo • Or upload GPX, FIT and TCX files from anywhere else • Your whole history in one place, however you recorded it KEEP SHOWING UP • The Climb turns consistency into altitude — every day you run earns height • Capped at four days a week, so you cannot climb faster by overtraining • It never goes down. A bad week costs you progress, never your progress so far RUN WITH OTHERS • Leaderboards and monthly challenges • Crews for training with friends • Personal records tracked automatically FREE FOREVER The race-time predictor is free with no signup. Premium unlocks the coaching loop — adaptive plans, insights, nutrition and analytics. IMPORTANT PaceBrain gives general information and is not medical, dietetic or professional coaching advice.

Your Apple Watch measures a great deal. Narelia compares it with you, not with a chart of what counts as normal: heart rate variability (HRV), resting heart rate, breathing and sleep, held against your own sixty-day baseline, with the arithmetic shown. Readiness, recovery, stress, your night and your vitals, each against your usual range. No black-box scores, and nothing leaves your iPhone. WHAT YOU'LL FIND INSIDE Readiness: how you arrive today. It starts from your morning recovery and moves with what your watch measures through the day. When there is no night to start from, it says "Daytime only" and counts only what has been measured today. Recovery against your own baseline. Each morning your HRV, resting heart rate, breathing and sleep are compared with your own nights, and the screen says which signal moved it and by how much. Your night, stress and vitals. The night by stage, stress through the day, and heart rate variability, heart rate, breathing and oxygen, each on its personal range. When a signal sits outside your usual range, Narelia says so in numbers. It describes; it never diagnoses. Fitness. The week's effort against your usual weeks, with your workouts and strength sessions. With Narelia Pro, choose the days you train and get suggested weights for your next session. While a baseline is still forming, the screen counts the days it has out of the days it needs, instead of showing a number that means nothing yet. LOG IN A TAP Water and caffeine go in with your own bottle, cup or can, drawn in 3D: drag the level to where it stands. Creatine and protein too, with quick amounts. Water, caffeine and, if you log it, alcohol also go to Health, and breathing sessions count as mindful minutes. Meals: take a photo and Narelia suggests what is on the plate; you confirm or correct it. The photo is read on your iPhone itself, with Vision and the Apple Intelligence model on compatible iPhones. Or log by text or by hand. Set calorie and macro targets and see what is left today. ASK APPLE INTELLIGENCE Ask for your readiness, your recovery, last night, water or caffeine, or log what you had by voice. Apple Intelligence can look up your own figures in Narelia (on supported devices and iOS versions). ON YOUR WRIST AND YOUR SCREENS An Apple Watch app with your vitals, your night and what you have taken so far, plus complications with your recovery on the watch face. Widgets for your Home Screen and Lock Screen in four styles. WHAT NARELIA DOES NOT DO It does not diagnose. It does not prescribe. Training and sleep figures are general information, not medical advice. No ads and no analytics. PRIVACY No account and no server of its own: your data lives on your iPhone and in the Health app. The iCloud copy is optional, goes to your own account, and stays off until you turn it on in Settings. Meal photos are analysed with the models Apple ships in the system and do not leave the device. Narelia is not a medical device and is not a substitute for a healthcare professional. If something worries you, talk to a doctor or other healthcare professional. SUBSCRIPTION Narelia Pro: the App Store shows the price for your country.
