Every workout from Garmin and Strava, in one curve.

The gap

Analytics apps don’t coach. Coaching apps don’t go deep. VerticalK does both.

Strava

Social network. Shallow analytics, no real planning.

Intervals.icu

Deep analytics. No coach. Built for spreadsheets.

TrainingPeaks

Coach-led planning. Paid. No real AI agent.

VerticalK

Deep analytics and a real AI coach. Both, free.

Every workout, pro-grade analytics

Import from Garmin and Strava. We auto-derive TSS, intensity factor, normalized power and time-in-zones, and roll it into a 90-day load curve — no spreadsheet required.

Weekly load +40%

Build blocks, recovery weeks and your taper, all visible.

An AI coach that acts, not a PDF

Ask in plain language. The agent proposes real workouts, you accept them, and they land on your schedule. It reviews finished workouts, responds to low readiness, nudges missed sessions, and recaps your week — on its own.
