The Precision Rowing Dashboard for Your Rowing Machine
Connect seamlessly to your Bluetooth FTMS rowing machine. Track live split-second stroke telemetry, follow structured multi-week training schedules, and analyze your progress offline without mandatory accounts or subscriptions.
Structured Multi-Week Training Schedules
Move beyond random workouts. RowerCore now features structured progressive schedules with dynamic relative scaling to help you systematically build endurance, power, and rhythm.
Multi-Week Guided Programs
Follow curated multi-week plans like the 2-Week Beginner Jumpstart, 4-Week Foundation & Cadence, or 4-Week High-Metabolic Fat Loss & Calorie Burn. Each plan organizes workouts by week and day with clear rest and training days.
Individual Baseline Gearing & Dynamic Scaling
Resistance on a rowing machine functions like bicycle gearing. RowerCore uses your calibrated personal baseline to dynamically scale interval targets (from steady warmup recovery to sprint intensity) so every workout matches your individual capacity.
Active Dashboard & Missed Workout Alerts
Your active schedule appears right on your home screen. Track current week progress, completion percentage, and next scheduled sessions. If you miss a scheduled day, the app notifies you so you can catch up without losing momentum.
Online Schedules Catalog & Custom Builder
Browse and download cloud-verified training programs from the online catalog, or use the built-in Schedule Builder to assemble your own custom multi-week schedule tailored to your goals.
