Comparison

TrainingPeaks vs Intervals.icu

Two tools that show you data but never tell you what to do with it. There's a better way.

TL;DR

TrainingPeaks is a calendar-based planning tool built for human coaches. Intervals.icu is a free analytics platform built for data nerds. Neither is an AI coach. Watts combines structured planning with deep analytics AND adds daily adaptation, metabolic profiling, and three AI coaches — Marco (endurance), Lucas (strength), Ana (nutrition) — working as one team. One plan, $24.99/month, 7-day free trial. Launching soon.

What athletes say after switching

“I used TrainingPeaks for planning and Intervals.icu for analytics. Two apps, neither coached me. Watts replaced both and actually tells me what to do.”

H

Henrik J.

Cyclist, 9h/week · Switched from TrainingPeaks + Intervals.icu

“TrainingPeaks gave me a calendar. Intervals.icu gave me charts. Watts gives me answers. "Should I ride hard today?" — instant response with my actual recovery data.”

M

Maria L.

Triathlete, 6h/week · Switched from TrainingPeaks Premium

“I was spending $20 on TrainingPeaks and still manually adjusting every week. Watts costs the same and does it automatically. Plus metabolic zones, which TP doesn't even offer.”

C

Carlos V.

Cyclist, 11h/week · Switched from TrainingPeaks + Intervals.icu

“Intervals.icu is still the best free tool. But "free analytics" and "AI coach" are different products. I use Watts for coaching and check Intervals.icu for deep dives.”
