Detailed Breakdown
Regatta and Watta serve overlapping but distinct audiences within the rowing world. Regatta aims to be the social hub for all rowers — connecting on-water clubs, sharing race results, and building community across the sport. Its strength is breadth: it covers the social side of rowing culture beyond the erg. Watta, by contrast, goes deep on erg performance. The AI OCR captures every PM5 metric from a single photograph. The Effort Score combines cardiac load, work output, pacing, and economy into a single quality metric. Split trends, watts per stroke, and heart rate zone analysis give rowers the tools to understand and improve their indoor training. For erg-focused athletes who want the best possible session analysis, Watta provides significantly deeper analytics. For rowers who want a social platform that spans indoor and on-water rowing, Regatta offers broader community features.
