One session, every device
Heart rate straps, action cameras, smart eyewear and the Concept2 ergometer all feed the same Oarca session.
A rower's training data tends to end up scattered: heart rate in one app, video on a camera card, erg scores in a notebook. Oarca pulls it together, so everything from one outing stays in one place.
Heart rate, live
Pair a heart rate strap such as Polar and follow your heart rate live while you row, right next to pace, strokes and stroke rate on the landscape dashboard.
Cameras and eyewear
Action cameras, including the Oarca 4K camera and GoPro, connect to the same session, and Engo smart eyewear can show your numbers without looking down at the phone.
Indoors on the erg
In winter or bad weather, connect the PM5 monitor of a Concept2 ergometer and row with the same app. Indoor sessions land in the same history as outings on the water, with the same summary and splits.
