Your guesses now tell their whole story. Tap any scored workout or sleep guess to see the full heart rate chart, your guess lines drawn right on it, and a marker where your call met reality. Press and drag on any chart to inspect every reading, now on Insights and guess details too. Hearts beat like hearts again. The classic lub-dub rhythm is back on every theme, on iPhone and Apple Watch. Plus theme polish, better Reduce Motion support, and under-the-hood hardening.

This one's a polish pass on last week's theme update. New: match your app icon to your theme. Own a theme (or have Plus) and you can set its icon right from the theme picker. Your watch now tells you up front if heart rate access is turned off, with steps to fix it, instead of leaving you waiting on the reading screen. Practice guesses past your daily counted limit are clearly marked in the Guesses tab now, and your watch gives you a heads up on the first one each day. Also fixed: the paywall could name the wrong theme, and the app sometimes asked you to pair your watch on a cold morning open when it was already paired. Plus small visual tuning across all ten themes.
