An iPhone app that reads FIT files from cycling computers and estimates power, training load, fitness, fatigue, and other ride metrics.

Why it surfaced

Wattmark makes a notably careful promise: it estimates power only on climbs of 4% or more, presents estimates as ranges, and refuses to produce numbers where wind and aerodynamics make them unreliable. Its AI coach explains which measurements support each conclusion, then recommends a specific next ride; the first analysis is free, followed by a subscription.
