Vitora vs Endyr.AI

Vitora is a health and fitness tracker for iPhone that does exactly what the name promises: it computes. No cloud algorithm crunches your data, no account is required, no server ever sees your numbers. Everything happens on your phone. Four scores give you a clear picture every morning: Recovery Score Your overnight HRV, resting heart rate, respiratory rate, and sleep, measured against your own baseline instead of a generic scale. Strain Score Your training load from real workouts, calculated with Karvonen heart rate reserve zones and the Acute:Chronic Workload Ratio from sports science. Body Battery An ongoing energy index that recharges overnight and drains through the day with activity. Sleep Score Duration, quality, and consistency, read directly from your HealthKit sleep stages. The four scores add up to a single recommendation: push hard, hold steady, or rest. Every formula is transparent, there’s no black box. Logging food takes seconds: snap a photo, type a quick description, dictate it, or scan a barcode. The AI analysis runs either right on your iPhone through Apple Intelligence, or through Vitora AI, always with your consent first. The Correlation Engine goes a step further: tag your day with things like caffeine, alcohol, or late meals, and Vitora runs a Welch’s t-test to see how it actually affects the morning after. Real statistics instead of guesswork, all computed on the device. Your dashboard, your rules: cards you can freely reorder, four visual themes from clean to industrial, plus home screen widgets and Siri shortcuts for the Action Button. Milestones like your first HRV baseline or a 7-day recovery streak quietly settle into an archive. No confetti pop-ups, no streak pressure. Privacy at Vitora isn’t a clause, it’s the architecture: there’s simply no server for anything to be sent to. Your data stays in Apple Health, a local database, and your iPhone’s keychain. Vitora is completely free, every feature included, no subscription and no ads. If it helps you and you’d like to support the development, please let a review in the App Store.

Everything you track sees part of the picture. Endyr reads all of it — training, recovery, sleep and fuel — and makes one call for the day. YOUR MORNING, AS WEATHER Your readiness arrives as a sky. The colour of the screen tells you how the night went before you read a single number, and one line says what it means for today. Underneath, a short brief explains what changed and why — measured against your own baseline, not a population average. EVERY SESSION, CAPTURED Start a session, tick blocks off as you go, log results block by block, and rate how hard it felt once you're done. Your coach's plan is there if you have one. Train yourself? Endyr writes your training — join in the app, answer a few questions, and your first session is ready before you've laced up. YOUR BODY, EXPLAINED Sleep and its stages, heart-rate variability, resting heart rate, respiratory rate, body composition — each shown against your own baseline, so the explanation matches the number you woke up to. FUEL Log a meal by photo, text or barcode. Save the ones you eat often, search foods, set one target for every day — or split training and rest days — and watch the week trend. ASK A coach you can ask anything, answering from your own data rather than general advice. FOR COACHES A squad roster that says who needs you first, each athlete's day in detail, a training review, competitions, and weekly programming you can write from your phone. CONNECTS TO WHAT YOU ALREADY USE Endyr reads from the major wearables, watches, rings, straps, smart scales, strength apps and nutrition trackers — and from anything that writes to Apple Health or Health Connect. Connect once and it keeps itself current. NO WEARABLE? IT STILL WORKS. Answer five questions in the morning and Endyr reads your day from those. The part that matters most — how much you can absorb — doesn't need a device. Endyr is a coaching and informational tool, not medical advice. Apple Health access is read-only and never used for advertising. Terms of Use: https://endyr.ai/terms.html
