RunNerd™ coaches every run — a spoken debrief, multi-week race plans that adapt, and an AI coach you can ask anything — on any device. Run with a watch and you also get maps, heart-rate zones & splits; run with just your phone and the coaching's exactly the same.
Works however you run — Apple Watch, Garmin, COROS, Nike Run Club, or just your phone, through Apple Health.
I'm not a runner by background. I'm a lifter who became a runner — and the app I needed didn't exist. So I built it.
A few minutes with the founder.
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 →Pick a distance and a date, get a plan structured across Foundation, Build, Peak, and Taper phases. The plan changes with you — pause when life happens, switch goals when they shift.
See how the plan works →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.
