What's New in Correlate

2.3.1

July 17, 2026

A sharper, more consistent look — and a Weekly Digest that gets to the point. • A refreshed design language: one accent system across every screen — green for your body, blue for actions — with unified cards, cleaner typography, and color-coded metric categories in Deep Dive. • Correlator, refined: the X and Y axis pickers now carry the app's signature colors, and the date range (7 days to 1 year) moved out of a hidden menu into one-tap chips right above the chart. • Weekly Digest, redesigned: it now opens with the conclusion — how many metrics improved, what needs attention — with week-over-week comparison bars for every metric. • Fairer trend colors: improvements are judged by what's actually good for each metric. A falling resting heart rate now correctly shows as progress, not decline. • Under the hood: cleanup and stability improvements. All on-device, all included in the one-time purchase — no subscription, ever.
