FORGE A STRONGER ENGINE. Your Concept2 erg gives you numbers. Row Forge turns them into a personal training system: know where you stand, train with purpose, and see the progress. Connect your PM5 over Bluetooth and every session is captured as you row. Then Row Forge does what a spreadsheet never could. It tells you what the numbers mean and what to do next. MEET ROW FORGE INTELLIGENCE • Today's Workout — one clear session, chosen for you from your fitness tests, training history, and campaign progress, with the reasoning behind it. • Post-Workout Analysis — see what each workout meant and what to carry into the next one, grounded in the work Row Forge recorded. • Ask Row Forge — a training conversation that knows your history. Ask what to train, how a session went, or where to focus next. TRAIN WITH A SYSTEM Test. Train. Learn. Improve. Row Forge connects the pieces so every session has a place and a purpose. • Viking Power Profile — establish your baseline, see your strengths and biggest opportunities, and train to targets built from your own results. • Fitness Tests — benchmark the distances that matter and retest to measure the difference. • Signature Workouts — structured sessions with targets set to your ability. • HIIT — interval work with adaptive power targets that move with you. • Campaigns — training blocks that give every session a sequence and a purpose, from your first row to a stronger engine. • Free Row, Free Ski, and Free Cycle — build your own session on any Concept2 erg. • Live session view — watts, pace, stroke rate, heart rate, and interval targets in real time, with your Apple Watch along for the row. • Logbook — your complete performance history with analytics, achievements, and sync with your Concept2 Logbook. • Cold Impact — track cold exposure alongside your training and see how it relates to your rowing.

Verdict
The clearest difference is in-app purchases: Iounn at none against Row Forge's 6. Iounn also leads on update cadence (every 2 days vs fortnightly). Row Forge's advantage is device support (4 vs 2) and iOS requirement (15.1 vs 26.0). On price and ads there is nothing between them.
