About
aftererg helps Concept2 rowers understand their training data more clearly.
Built for athletes, fitness rowers and everyday users alike, the app transforms ErgData, Concept2 and workout history from any other source into visual comparisons and performance insights that are easy to explore.
Instead of only tracking totals and personal bests, aftererg helps you see:
• How pacing changes across workouts
• Consistency and fatigue patterns
• Similar-session comparisons over time
• Interval structure and recovery behaviour
• Long-term trends in training quality
Designed with a calm, data-first interface, aftererg focuses on helping you understand your own rowing story — whether you’re training seriously or simply trying to row more consistently.
Features include:
• Workout comparison tools
• Efficiency map visualisations
• Similar-session analysis
• Detailed interval breakdowns
• Historical performance insights
• ErgData / Concept2 Logbook integration
aftererg is independent and not affiliated with Concept2.
