PB-Runner

About this app

Most running apps lock you into their own built-in coach. PB-Runner does the opposite: it connects an AI assistant you already subscribe to — such as Claude, ChatGPT or Gemini — to your own running data, so that AI can read your runs, write your training plans, and build custom sessions for you to follow on your phone.

RECORD YOUR RUNS
• GPS tracking with pace, distance, splits, cadence, stride and elevation.
• Detailed run breakdowns with route maps.
• Your full run history, synced across your devices.

CONNECT YOUR OWN AI (optional)
Link an AI assistant you already pay for, build your Athlete Profile, and ask it to:
• Read your recent runs and tell you how your training is really going.
• Write a training plan around your goal and your current fitness.
• Construct custom sessions — intervals, pyramids, tempo and progression runs — with every rep and recovery spelled out.
Whatever it builds lands in your schedule, ready to run guided on your phone with spoken cues. PB-Runner is only the connector between your data and your AI: that AI is your own separate subscription, under that provider's terms, and the app works fully without it.

FOLLOW YOUR PLAN
• A training schedule you or your AI can build, each session ready to run guided on your phone.
• Coach notes and paces calibrated to you — not a generic runner in an age bracket.

SHARE YOUR RUN
• A built-in editor for sharing your runs — stats over the map or your photo, dragged into place and styled to match.

MORE
• An analytics dashboard on the web at pb-runner.com.
• Race pages and finisher results for events you join.

PB-Runner is free while we launch — record your runs, sync across your devices, and see your stats. Connecting your own AI is included free for now and will become a paid option later; your recording and history always stay free.

PRIVACY
Your location and health data is used only to run the features you use — never for advertising, and never sold. It is shared with an AI only when you explicitly choose to connect one, behind an in-app consent screen.
