About ErgManiac

ErgManiac was born out of a simple frustration: existing erg tracking tools were either too basic or too expensive. As a rower who logs workouts on a Concept2 almost daily, I wanted something that goes beyond just recording splits -something that actually helps you get faster.

So I built it. ErgManiac combines automatic workout tracking with AI-powered coaching based on proven polarized training methodology. Whether you scan your Concept2 screen, sync from Concept2 Logbook, or enter workouts manually, the app analyzes your data and generates personalized training plans tailored to your goals, age, and fitness level.

The Team

Dominik Dragicevic

Founder & Developer

Developer and rowing enthusiast based in Croatia. Built ErgManiac with the support of CoreLine Agency, a software development studio specializing in web and mobile applications.

Our Mission

We believe every rower -from the person who just bought their first erg to the masters athlete chasing a PB -deserves access to intelligent, data-driven coaching. Not everyone can afford a personal coach, but everyone can benefit from one. That's the gap ErgManiac fills.

The Methodology

Our AI coaching is grounded in polarized training principles used by elite rowing programs worldwide. Think 80% low-intensity steady state, 20% high-intensity work, structured across five training zones (UT2, UT1, AT, TR, AN). We draw inspiration from coaches like Jack Burns and the Edge Rowing methodology, FISA guidelines, and sports science research -adapted for real people with real schedules.

Our Knowledge Base

The AI coaching system draws from 61 curated knowledge entries covering rowing technique, training theory, periodization, race strategy, and common mistakes. Sources include FISA (World Rowing) coaching guidelines, elite rowing methodology, and content from experienced coaches. Every coaching response is grounded in evidence-based practice.

How ErgManiac Works

ErgManiac is a progressive web app (PWA) that works on any device - phones, tablets, and desktops. It can be installed to your home screen for a native app experience. Workouts are stored securely, and user data is never shared with third parties. The platform is compatible with all Concept2 indoor rowers and performance monitors (PM3, PM4, PM5).
