Personal Bests finds the fastest efforts hidden inside your workouts and awards you medals for them, with nobody to compete against but yourself. Your fastest 5K might be kilometers 7 to 12 of a half marathon. Your best mile might be buried in the middle of a long run. Personal Bests looks inside every workout in Apple Health, finds your fastest segment for every distance you care about, and ranks it against your whole history. Just You vs. You Personal Bests isn't a social network. There's no feed, no followers, no leaderboard of strangers and no challenges telling you to go faster. You earn gold, silver and bronze for real work, and the only person you're up against is you. Your Game, Your Rules • Choose the distances that count: 400 m, 5K, 10 miles, a marathon or anything else, for every sport. • Choose what you're compared against: all-time, the past year, or any window of days, weeks, months or years. • Coming back from an injury or a break? Rank against the last three months instead of your all-time best. • Keep the medals you've earned, even after you beat them, or let them move on. • Rank indoor and outdoor workouts separately, so a treadmill run isn't compared with a trail run. Find Your Fastest Efforts • Segments can start and end anywhere in a workout, not just at the start. • Running, cycling, swimming, rowing, paddling, walking, cross-country skiing and more. • Your whole Apple Health history, from Apple Watch, iPhone and other apps. • New workouts are analyzed automatically, even in the background. See Where You Were Fastest • On iPhone, your fastest segments are drawn on the route, each in its own color. • Leaderboards for your fastest times, longest workouts and farthest distances. • A short written summary of any workout, using Apple Intelligence where it's available. Keep Bad Data Off the Podium • Forgot to stop your watch on the train? Segments that are too fast to be true for you are flagged, judged against your own history. • Crop a workout to the part you actually did, or remove GPS spikes with one tap. • Your Health data is never changed. Celebrate Your Progress • Get a notification when a new workout earns a medal. • "While you were away": a recap of your new medals and training when you come back to the app. • Rankings and Recent Bests widgets for the Home Screen and Lock Screen. On iPhone, iPad & Mac • Your iPhone reads Apple Health and does the analysis. • iPad and Mac show your workouts, rankings and medals, with the list and details side by side. Private by Design • No account, no ads, no tracking. • Analysis runs on your device. • Syncs only through your own iCloud, and you can switch that off. • Read-only access to Apple Health. Make It Yours • Three app icons and three themes. Personal Bests is for anyone who loves earning medals but doesn't need to race strangers for them: runners tracking PRs from 400 m to the marathon, cyclists comparing their best 40K across seasons, swimmers, rowers, and everyone who has ever wondered, "When was I actually at my fastest?"
