Trackables turns the Activity, Heart, Sleep, and Steps data your iPhone and Apple Watch already collect into four glanceable cards — activity rings, resting heart rate and HRV, hours slept and wake-ups, daily distance. There’s no account, no sign-up, and no cloud sync; your health data stays on the device, though the app does use anonymized TelemetryDeck analytics. It’s free to download and use today on iOS 26, though the makers note some features may become optional purchases later.
