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 Missing or outdated data is identified clearly.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.

Calmgraph turns your daily stress into one number you can actually act on - fully on-device, no subscription. โ Stress score (0-100) From Apple Watch HRV, resting heart rate, and sleep, measured against YOUR personal baseline rather than a single absolute value. The first 14 days are a calibration period shown as provisional. โ Cause tags and calendar Tag work, sleep, exercise, caffeine and more, layered onto your score. The calendar view shows a month at a glance, and you can tap any past day to fix its tags or check-in. โ Weekly insight and tag correlations See what likely moved your score each week. The Pro correlation report compares your average on days with a tag against days without it, and always shows the sample size. These are correlations, not conclusions. Step count, respiratory rate and deep sleep appear alongside as automatic tags, split at your own quartiles. They never change the score itself. โ Apple Watch and widgets The Watch app and complication put your score on your watch face and let you check in from your wrist - free. Home and Lock Screen widgets are part of Pro. โ Breathing guide and reminders A 1, 3, or 5 minute breathing guide for the days that sit in the strain band. Daily logging reminders and a weekly review notification are optional. โ One-time purchase and backup Buy once instead of subscribing. There is no cloud sync, but you can export a backup to a single file and restore it on another device. โ Monthly & yearly summary / Weekly history (Pro) Averages by month and year, with the calm / mixed / strained mix. Past weeks with their average and what was moving your score. All measurements are processed on your device. Nothing is sent off-device, collected, or used for advertising. Calmgraph is not a medical device and is not intended to diagnose or treat any condition. Consult a healthcare professional about any health concern.

Verdict
The clearest difference is in-app purchases: RunReady Copilot at none against Calmgraph's 1. RunReady Copilot also leads on iOS requirement (17.0 vs 26.0). Calmgraph's advantage is update cadence (every 4 weeks vs every 5 months). On price, ads and device support there is nothing between them.
