Every stroke, in focus. Pair your Concept2 RowErg and row. Your workout is written to your phone first and integrates with Apple Health, your Concept2 logbook and iCloud. WHILE YOU ROW • Focus, or all the data — two views, a tap apart • Your split, big enough to read mid-stroke; rate, watts, distance and time a glance away • A target pace you set, with the split turning orange the moment you drop behind it • Workout to a fixed distance or time • Live heart rate from your Apple Watch BEFORE YOU START • Send a distance or time workout straight to the monitor, splits and all • Pairs over Bluetooth and reconnects on its own WHEN YOU STOP • Splits, a pace chart and a stroke profile for every piece you’ve rowed • Written to Apple Health • Shared to your Concept2 logbook • Synced to your own iCloud, so a new phone starts with your history already on it ON YOUR WRIST • Heart rate on the watch while you row PRIVATE No adverts. JustRow has no server of its own: your rowing lives on your phone and in your own iCloud, and reaches Concept2 only when you sign in and ask it to. Requires a Concept2 RowErg with a PM5 monitor. An Apple Watch is optional, and used only for heart rate. Concept2 and RowErg are trademarks of Concept2, Inc. JustRow is an independent app, not affiliated with or endorsed by Concept2.
