"Why do I feel like this today?" — the answer might already be in your data. How you feel is never one thing. Sleep, the state of your mind, what yesterday was like, the air today. Each is recorded somewhere separate, and only means something once they are put together. Attune lines them up as one flow, and reads today against your own usual. ■ Today, in three numbers Condition, Body Battery, Stress. Whether you have recovered, whether you have room left, whether you are wound tight. Whether today is a day to push or a day to rest. The baseline is your own usual — the same number means different things for different people. ■ Telling a hunch from a fact "I always feel worse on days like this." Is that actually true? Attune looks for the relationship in your own records and tells you how sure it is. It does not assert. It is a tool for checking. And when the evidence is not there, it says so rather than inventing a pattern. ■ Keep the apps you already use Attune does not ask you to switch. Whatever reaches Health is read and used, whichever app or device wrote it. Whether your sleep comes from a watch or a ring, your meals from another app, your weight from a scale — it all lands on the same line. If a kind of record is not arriving yet, Attune suggests apps that can record it, right inside the app. Logging in Attune itself is there for when you don't use an app, and what you log is written back to Health — so even if you stop using Attune one day, your data stays with you. What is arriving, what is missing, and what each missing piece would let you learn — you can see all of it from day one. ■ Light enough to keep up Mood is one tap from a single line on Today. The rest is taps too. A record you cannot keep up is worth nothing, so the work has been cut as far as it goes. No Apple Watch needed — enter your sleep by hand and your Condition appears the same day. ■ Attune Premium These features come with Attune Premium, an auto-renewable subscription (monthly or yearly): - Pattern discovery (weekday habits, sensitivity to pressure and temperature swings, how sleep and places relate to how you feel, the results of what you tried) - Trends longer than 30 days (3 months, 6 months, 1 year) and the summary for your doctor - Apple Intelligence summaries and advice for today, and questions about your own data If you have used Attune since before version 2.5.0, everything you have today stays free. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Cancel any time in the iPhone's Settings › your name › Subscriptions.
