What's New in Heartio
1.1.4
August 26, 2026
A smarter Insights tab. Your Accuracy trend now lives at the top of Insights in every theme. Tap any day's bar to jump straight into that day's details, or press and hold to scrub across the week. The trend line below scrubs too. Sleep guesses grew up. The sleep result screen now shows last night's chart with your guesses on it, just like workouts. Feels better everywhere. Tapping a tab again takes you back to the top, Ember's Lifelines heart beats again, and dozens of small copy touch-ups.
