Personal Bests vs PBSplits

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?"

PBSplits is a free app that finds your fastest split at every standard distance across your run history. Most personal-best tools only know your finish times. If you've never raced a 5K, they think you've never done one. PBSplits looks inside each run and finds the fastest continuous window for every distance on the ladder, so the best 5K you ever ran shows up even if it was the middle 5K of a 12 K training jog. Three tabs, and it opens on the first. Runs is every run in your Health data — pull to refresh, tap any one to open it, even the ones that never hit a standard distance. Trends plots a distance over time, as pace or as finish time, with a year-over-year view to lay this season against the last; it also holds the Power Curve, your season's distance against last year's, and your weekly run streak. Me is your season and all-time totals and the record book: the ladder from 400 m to 100 K, grouped Short / Road / Ultra. Tap any effort and you get the whole run — the route on a map with the record-winning segment highlighted, a mile-by-mile splits table, and pace and elevation charts. Tap a split and its window lights up on the map and across the charts, so you can see exactly where you found the time. Season and all-time crowns mark the efforts that took a podium. Great for: • Runners who want PBs from training, not just races • Tracking progress over a season or a year • Finding the fastest you've ever covered a 5 K, 10 K, half, or marathon • Comparing efforts across short, road, and ultra distances • Anyone whose watch knows more than they do What you get: • Best-effort engine that finds your fastest continuous split at every distance, not whole-run averages • Full distance ladder from 400 m to 100 K, grouped Short / Road / Ultra • Every run, browsable: pull to refresh, and open runs that never hit a standard distance • Trend charts, progression and year-over-year, by pace or by time, pinch to zoom either axis • Mile-by-mile splits: tap a split to highlight its window on the map and the charts • Your watch's own laps and workout intervals, each in their own table • Power Curve: your best pace at every duration, from 30 seconds to your longest run, switchable to heart rate, for a season or your own date range • Weekly run streak, with every run day's distance on a heatmap • Export any run as a GPX or FIT file • Map view per effort, with the winning segment highlighted on the route • Season and all-time crowns on podium efforts • Share cards for a new PB, a podium, or your whole record book • Pick your pace units: min/km or min/mi • PBSplits reads your workouts from Apple Health and never writes to it • Your run data stays on your device Free to download — no subscription, no account.
