RunNerd reads every run — pace, heart rate, cadence, splits — and translates the data into coaching, plans, and progress you can feel. Built for runners learning the sport and runners chasing a PR.
Works with Apple Watch, Garmin, Fitbit, and any watch that syncs to Apple Health.
Coaching that pulls from your last run, your last week, and your last race. Ask anything; the answers come back grounded in your data, not someone else's playbook.
See how the coach works →Your plan generates Sunday and reshapes itself when you do. Skipped Tuesday? Pushed too hard Saturday? The plan adjusts before Monday rolls around.
See how the plan adapts →Run classification, HR zones, cadence, splits, and route trends — translated into plain English. The patterns were always in your data. Now you can read them.
See the insights →A newbie started running, and the watch collected everything from day one. The trends were there from the start — they just couldn't read them. RunNerd is the tool they wish they'd had.
