PB vs PBSplits

PB-Runner is a running app that records your runs with the full depth your watch/phone can capture - pace, distance, splits, heart rate, and running-form metrics like power, ground contact time, vertical oscillation, stride length and cadence - and shows them in detail with route maps. - Record runs on Apple Watch (standalone, phone left at home) or on iPhone. - Garmin Support with PB-Runner ConnectIQ app - Detailed run breakdowns, route maps, and splits. - Create custom training schedules with AI you can follow on your wrist/phone with audio and haptic cues. - Recovery context from Apple Health (resting heart rate, sleep, HRV, VO2max). - An analytics dashboard on the web at pb-runner.com. - Share your run with a built-in editor for sharing your runs — stats over the map or your photo, dragged into place and styled to match. Bring your own AI (optional): connect an AI you already use - Claude, ChatGPT, Gemini or another - to your own training data and build your Athletes Profile so it can analyse your runs and help plan your sessions based on the athlete you are, not a generic runner in an age group . PB-Runner is the connector; the AI is your own separate subscription, and the app works fully without it. PB-Runner is free while we launch - record runs, sync across your devices, and see your stats. Connecting your own AI is included free for now but will become a paid option later; your recording and history stay free. Privacy: your health and location data is used only to run the features you use, never for advertising, and never sold. It is only shared with an AI when you explicitly choose to connect one.

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. Bests is 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 • 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.
