Tell ChatGPT or Claude what you're training for, and your plan lands in PB-Runner, where it can play as guided sessions on your watch or phone. Now in both official directories: a plugin in ChatGPT and a connector in Claude. A free account works on either. - 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: connect an AI you already use - ChatGPT, Claude or another - to your own training data and build your Athlete 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 account, and the app works fully without it. PB-Runner is free to download. Recording every run, your history and stats, exporting your data, and your AI reading your training and saving a plan all work with no subscription. Your first training block plays in full as guided sessions, with no card needed. After it, guided sessions and Custom Runs require a subscription: PB-Runner Monthly or PB-Runner Yearly, billed to your Apple Account. A subscription renews automatically until you cancel it, at least 24 hours before renewal, in your Apple Account settings. Terms of Use: https://pb-runner.com/terms Privacy Policy: https://pb-runner.com/privacy 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.

About

PBSplits

Read full description

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.
