Your workout keeps running when your phone is locked, so countdown beeps carry on and the lock screen stays current. The lock screen shows each phase in its color and, with a heart rate sensor, your heart rate with Push, In range or Ease off. A new target bar shows where your heart rate sits in your range during every work interval. Workout overviews now explain their colors, and indoor workouts no longer show an empty pace.

Small improvements.

Workouts you save now always count toward your activity, streak and totals, even without Apple Health. New: choose your heart rate sensor. PEAKVO2 connects only to the one you pick. You find it on every workout page and in Settings. One Health permission request instead of several, plus smaller fixes.

Your weekly plan now shows your number and where it came from, and it can read a VO2 max that Apple Health already has. A new morning card reads last night and suggests what to do today. You can start the plan over, and your test results are visible and removable where you took them.

Your workout now keeps running when you leave the screen. Minimize it, browse the app, and tap the bar above the tabs to jump back in. Also a quieter error log and small fixes.

New: a feedback board built for you. Share ideas, vote and comment, no account needed. Find it in Settings under Feature Requests. Also in this update: • Workouts started from your plan on Apple Watch now count toward your weekly plan • Bugfixes

To the one user who kept sending feedback: you know who you are. Thank you. It shaped everything in this release. This is our biggest update yet: • Your 8 week plan: a science based programme that adapts to your fitness level, week by week • Weekly plan on the Workouts tab: two interval days, Zone 2 and strength, tick them off as you go • Session verdicts: every workout is judged against its own protocol's standard, with heart rate analysis and zone minutes • Session details: heart rate graph with target band, compared to your earlier runs • Fitness reveal: see your level, your next level, and the fastest way there • A fresh onboarding that gets you to your number in about a minute • Available in all 11 languages

Your workout summary now reliably appears when you finish. It was being dropped on its way in, which also meant the app almost never got round to asking what you think of it. Stopping a workout early now shows the summary too, clearly marked as cancelled rather than complete.

Your workout now lives on the lock screen. The countdown keeps running while your phone is locked or the app is closed, and it no longer loses time if you step away mid interval. You can also send the Cooper Test, the 1.5 Mile Run and the Rockport Walk Test to the Workout app on your Apple Watch, run them there, and PEAKVO2 works out your result from what the watch measured.

A new Help and FAQ section in Settings. How to get your VO2 max into Apple Health and where to find it in the app, why Apple's own Cardio Fitness reading may be missing, how to connect a heart rate monitor over Bluetooth, and how the Apple Watch side works.

Train anywhere with no equipment. The Tabata Protocol and HIIT 30/30 now name the movement for every interval, burpees, mountain climbers, squat jumps and jumping jacks, so you can prop the phone up and follow along. Each one comes with a short how to before you start.

See your heart rate while you train. Connect a chest strap or any Bluetooth monitor and PEAKVO2 shows it live during the workout, tells you the moment you hit the right range in a work interval, and counts how long you hold it there.

Free VO2 max tests are back. Run the beep test with exact audio, the Cooper test with GPS, or enter a result by hand. Also new: the 1.5 mile run, the Rockport walk and heart rate calculators. Your result saves to Apple Health and shares as a card.
