Flowbase — Training for Rowers Who Race Flowbase is the all-in-one training app for competitive rowers: a coach, a smart erg log, readiness tracking, and live race results — built around how rowers actually train and race. Whether you're chasing a 2K PR, prepping for a championship, or managing a squad, Flowbase turns your erg pieces, wearables, and race history into clear, personal guidance. A COACH THAT KNOWS YOUR TRAINING - Ask FlowCoach anything: build a race plan, break down a piece, or decide whether to train through fatigue. - Before, after, or between sessions — get pacing targets, debriefs, and recovery calls grounded in your real data. A SMARTER ERG LOG - Log every piece by hand, by scanning your PM5 screen, or by importing a workout file (.csv / .fit). - Sync your Concept2 Logbook and your log fills itself — pieces, splits, and stroke data, automatically. ERG SPEED ORDER - See exactly where you stand with handicap-adjusted rankings that compare athletes fairly across age and weight. - Track your 2K, 5K, and 6K, follow your team leaderboard, and watch your rating move as you train. READINESS & TRAINING LOAD - Connect a wearable to see recovery, HRV, resting heart rate, and sleep at a glance. - Log a daily check-in to track training load and your injury-risk ramp — so you know when to push and when to back off. CONNECT YOUR DEVICES - WHOOP, Oura, Polar, Google Fit, Strava, and Concept2 — connect once and your data flows in automatically. REGATTAS & RESULTS - Browse race results, follow regattas, and find out exactly when your crew races. - Add a regatta that isn't listed and help build the most complete rowing calendar out there. BUILT FOR CREWS AND CLUBS - Chat with your crew, keep everyone on the same page, and (for coaches) manage your squad. Flowbase is made for rowers, coaches, and clubs who take racing seriously. FlowCoach provides AI-generated guidance and is not a substitute for your coach or medical advice.
