C25K 2.2 brings your run to your Home Screen, Lock Screen and wrist. • Widgets for your Home Screen and Lock Screen show your next workout, your progress and when it's a rest day • Start a run on your iPhone and follow it on your Apple Watch: the current interval, wrist taps for every change and your heart rate, with pause, skip and end on your wrist

C25K 2.1 adds an Apple Watch app and more. • Apple Watch: run with or without your iPhone. Voice cues through AirPods, wrist taps for every change, heart rate on screen, and workouts saved to Health • Reminders on the days and time you choose, telling you which workout is next • Ended a run early? The day waits for you, with encouragement for the long runs in weeks 5 and 6 • Keep 5K: once you finish Week 9, a three-run rotation keeps your 5K going • Voice cues now dip your music and pause podcasts, then let them carry on • Health workouts now include distance, route and every interval

C25K 2.0 is a complete redesign. • A new look and a new icon • New voice coaching in a female or male voice, with a heads-up before every change • A Live Activity on the Lock Screen and in the Dynamic Island • A Today screen with this week's tip, your last run and rest-day guidance • Press and hold to end a workout, so a stray tap can't stop your run • A clear notice when location is off, so you know why a run has no map • More reliable timing and audio when your phone is locked
