Ready for iPhone Duo. Drift adapts as you open, close or partly fold your phone. Clearer controls, readable fitness summaries and scrollable update notes improve smaller displays too.

Drift on Apple Watch now keeps up with your training. The watch app calculates today's strain from the workouts it records, so your strain and the Strain complication update even before your iPhone syncs. On a new morning, your strain target follows this morning's recovery from your watch. The watch asks once more for access to Health, to read your workouts and active energy.

Drift now lives on your wrist. The Apple Watch app shows how you're doing today and what to do right now, with live steps and heart rate, last night's sleep and this morning's recovery read straight from your watch. Three clear pages replace six, in a type made for small screens.

Apple Watch, easier to read at a glance: larger text on every screen, a bigger score on Home, and clearly named Strain, Recovery and Sleep rows. Plus small fixes and polish.

Accessibility fix: in light mode your Drift score and the “Calculating your Drift” text were rendering in white on a light background — both during setup and on the Drift tab. They now adapt correctly to light and dark.

A refreshed welcome that shows what Drift actually does before asking for anything, plus a calmer launch animation. • Tab headers and the 24-hour control now look and behave the same on every tab. • Ask Drift is scoped to the tab you open it from, so the questions match what you're looking at. • Onboarding picks up where you left off if it's interrupted. • Localization and accessibility fixes throughout.

Drift now speaks Swedish, Danish and Norwegian. • Every screen, score and coaching message is translated — including the Apple Watch app, the widgets and your notifications. • Apple Intelligence supports all three languages, so Drift's on-device AI writes your daily insight and answers your questions in your own language. As always, every calculation happens on your iPhone. Nothing leaves the device.

Drift on your wrist, when it matters. • Your Drift complications now show up in the Smart Stack on their own — your score as you wake, the bedtime window as the evening closes, strain during a workout, and UV while the sun is high. No need to add them to a watch face first.

Built for iOS 27, and a sharper HRV. • HRV now reflects your night. Drift averages the readings taken while you sleep, so daytime measurements from the newest Apple Watch models no longer pull your number down or unsettle your baseline. • Heart-rate zones can follow the Health app. On iOS 27, choose Apple Health Zones in Settings and Drift uses the zones you set in Health — plus Apple's own time-in-zone for new workouts. • On iOS 27, Recovery HRV (RMSSD) appears next to HRV as an extra reading. • Your sleep history fills in on its own. Nights no longer wait for you to open the app.

A cleaner Drift home. • Your seven category scores now sit in a balanced two-row layout — four across the top, three below. No more lone tile hanging off the end of the grid. • Each tile gives its name the full width, so longer category names stay readable, and the rows adapt when you use larger text.

Habit Coaching — set two habits of your own and let Drift help you keep them. • My habit plan (Settings → Habit Coaching): choose a daily movement target and a steady bedtime window, set your weekly goals, and pick when you'd like to be asked. Your targets stay where you set them — this is about consistency, not pushing your training load up. • Progress you can trust: completion is read from your own steps and sleep, planned rest days count toward your week, and missing data is never treated as a failure. • Quieter, more accurate notifications: no duplicate or stale prompts, and sleep messages now keep last night's duration separate from your recent trend.

Bedtime Window — a 14-night challenge for a steadier bedtime. • Your sleep score rewards a regular bedtime: nights within 30 minutes of your usual time earn full marks. The new Bedtime Window card on the Sleep tab shows tonight's window, your last 14 nights, and what landing in it is worth. • Start the 14-night challenge: hit the window on 10 of 14 nights, with a progress ring, night-by-night results, and an optional wind-down reminder.

Reliability under the hood. • A startup integrity check now guarantees every workout appears exactly once — even if an older version left duplicates behind. • Faster activity lookups, thanks to a new index on your workout records.

Localization polish across the app. • Text that still appeared in English inside the app's nine translated languages (German, Spanish, French, Italian, Japanese, Korean, Portuguese, Vietnamese, Chinese) is now fully translated — recalculation options, recovery recommendations, and the Drift Score, Recovery, and Streak detail views. • Correct singular and plural forms everywhere ("1 more day", not "1 more days"). • Times follow your region's format.

More duplicate activities caught — including ones from other apps. • Sessions recorded by other fitness apps now merge with the same workout from your Apple Watch, even when the two label the activity differently. Those were exactly the duplicates the last update couldn't catch. • If you also use Sleep Voice Memo, it now recognises that Drift is installed and opens Drift directly instead of offering the App Store again.

Sleep regularity, explained — and no more double activities. • Sleep regularity is now clear: the Circadian Rhythm card shows your bedtime spread next to rhythm steadiness, and explains why the two can differ — a fixed wake time keeps your midpoint steady even when your bedtimes drift. Your sleep score reads the bedtime spread. • Activities no longer appear twice in your activity list, and any duplicates already there are cleaned up automatically. • Sleep numbers now agree everywhere they appear in the app.

Your aerobic engine, front and center. • New VO2 Max card on the Fitness tab: your current value, how it has developed over 90 days, and where you stand among people your age and sex — tap for the full history. • Fairer walking-speed scoring: thresholds now adjust for sex as well as age, following the same research norms.

Every sleep stage, one tap away. • Tap any sleep stage — Deep, REM, Core, or Awake — for a full detail view: last night, your 14-night history, your 30-night average, and what that stage does for your body. • Fairer deep-sleep scoring: Drift now scores deep sleep against what wearables actually measure and your own range — consistent nights get the credit they deserve. • Sleep is now always shown in hours and minutes across the whole app — 7h 54m, never 7.9. • Two-week sleep trends are now tappable — and overnight HRV and resting heart rate join them, each opening a full history view.

Sleep, stated plainly. • Sleep now always reads as hours and minutes — 7h 54m, never 7.9. • Notification text is now verified against your actual data before it's sent — a notification can no longer state a number that didn't come from your day.

Truer numbers, quieter noise. • Notifications now stay silent when your Apple Watch hasn’t synced yet — no more false “0 min sleep” or low-activity nudges about a workout Drift hasn’t seen. • Pace of Aging now tracks each biomarker’s real trend: data gaps can’t read as faster aging, and recent months count more than last year. • The Apple Watch sleep score now matches the Sleep tab — both score your recent two weeks.

Fairer sleep regularity. • Bedtime regularity now measures your main night — an evening doze or a lost night can’t skew two weeks of scoring anymore. • One odd night no longer dominates: the regularity math is now outlier-proof. • While your body clock catches up after crossing time zones, those nights sit out of regularity — jet lag isn’t irregularity.

Jet lag is now a pattern. • Cross 3+ time zones and Drift recognizes it: the new Jet Lag pattern shows your adjustment window and why scoring is eased while your body clock catches up. • If Health access is ever off, Drift now says so plainly — with a one-tap route to the fix instead of an endless “calculating” screen. • Pattern details open instantly.

Reliability: workout syncing can no longer stall. • Workout, heart-rate and route reads now have a safety deadline, so a slow Apple Health response can't hold up your Drift refresh. • Continues the stability work from the last update.

Reliability improvements for a smooth start. • Fixed: the first-launch “Calculating your Drift” step could freeze until the app was restarted. • Fixed: a rare crash shortly after opening the app. • Sturdier Apple Health syncing when data is slow to arrive.

Notifications that learn what works for you. • Drift now notices which nudges actually move your day, and leads with those. • New: a gentle morning heads-up when your walking pattern drifts from your usual. • Fixed: the evening recap could quote a step count from earlier in the day.
