RunReady Copilot vs Cirrus Recovery

RunReady helps you plan today's run using Apple Health data and your own recent history. TODAY'S RUN See a suggested effort, the reasoning behind it, and available workout targets. Expand the score and data details to understand what contributed. iPhone guidance considers readiness and recent training information. YOUR PERSONAL BASELINE Resting heart rate, heart rate variability, respiratory rate and sleep can contribute. Each scoring signal needs at least seven valid observation days in the recent 30-day window, and at least two current signals are required for a score. Missing or outdated data is identified clearly. RUNNING AND RECOVERY Explore your health signals, running history, available recovery metrics and training information. On supported devices, on-device Apple Intelligence can provide an explanation; a built-in explanation is available otherwise. APPLE WATCH A compact Watch estimate, readable biometric rows, a refresh button and a watch-face complication. The Watch uses its own biometric calculation; see the iPhone app for training-aware run guidance. A home-screen widget is also included. PRIVACY No account required. Health data and derived results are processed and stored locally. Settings can sync between your paired iPhone and Apple Watch. No developer-operated cloud service or advertising analytics. RunReady provides general fitness information, not medical advice. Data availability depends on your devices and Apple Health records.

Cirrus reads your heart rate, HRV, sleep, and workouts from Apple Health and turns them into a single daily recovery score — computed entirely on your iPhone, every time. WHAT YOU GET • A recovery score from 0–100, updated each day • A clear breakdown of the factors behind it: heart rate, HRV, sleep, respiratory rate, blood oxygen, and training load • A 7-day trend so you can see how you're tracking over time • An intraday timeline showing how your score moved through the day • A short daily recap that puts today's numbers in plain words • Playbook: bite-sized, sourced articles on sleep, training load, and recovery habits • A companion Apple Watch app that shows today's score at a glance HOW IT WORKS Cirrus reads data you've already granted it access to in Apple Health, computes your score on-device, and stores the result on your device. That's it — no servers involved in your health data, ever. PRIVACY, BY DESIGN • Your health data never leaves your iPhone. Cirrus computes everything locally and has no way to access it even if it wanted to. • No account required — every feature works without signing in. • No ads, no analytics, no tracking SDKs of any kind. • Full details in our privacy policy, linked in Settings. Cirrus is a wellness and self-tracking tool, not a medical device. It doesn't diagnose, treat, or monitor any medical condition — for anything symptomatic, talk to a clinician.
