No external account or customer/personal data is stored by Scull.fit. All data is currently stored on the user's device and the device only.
Scull.fit turns your Concept2 PM5 into a smart coach. Connect via Bluetooth and get real-time metrics, technique feedback, and guided workouts — all on your iPhone.
LIVE METRICS
See pace, watts, stroke rate, heart rate, calories, and distance update in real time. Tap any metric to maximise it. Long-press to set a target — the tile flashes
green when you're on pace, red when you're off.
TECHNIQUE BADGES
Five badges track the quality of your rowing, not just the output:
• Stroke Power — watts per stroke
• Rhythm — drive-to-recovery ratio
• Force Curve — force effectiveness through the drive
• Consistency — stroke rate variation
• Cardio Power — watts per heartbeat (with HR monitor)
Each badge levels up from 1 to 3 during your row. Hit Level 3 and a celebration flash fires across the screen.
HYROX MODE
A dedicated 1000m row with guided coaching cues. Scull.fit tells you when to get on pace, when to drive, when to settle, and when to sprint the final 100m. Pace
targets are set automatically as you row.
INTERVALS
Build any interval workout — fixed distance or fixed time, with configurable rest periods. Set a different pace target per interval. Save your favourites as presets
for one-tap access.
CHASE YOUR PBs
Finished a great row? Swipe to Chase it. Scull.fit loads your previous targets and shows a pace boat so you can race yourself.
STATS & SCORES
Track your progress across six performance dimensions: Power, Efficiency, Technique, Consistency, Endurance, and Cardio. Spider charts and trend lines show how you're
improving over time.
SPLITS & CHARTS
Every workout saves detailed splits, pace curves, stroke rate graphs, watts charts, and heart rate data. Tap any chart to view it full-screen with pinch-to-zoom.
CONCEPT2 LOGBOOK
Sync your workouts with the official Concept2 Online Logbook to keep your lifetime metres up to date.
