Oarca is a rowing app built for the water and for the clubs that row on it. Track every stroke with your phone, follow a structured plan, book your seat in the club boat and see your progress week by week, month by month and year by year. YOUR ROWING, AT A GLANCE The home screen opens on your week. Switch to month or year, change the metric between time, distance, strokes and calories, and pull the week down to see every day as a bar. Your last workout and your next booked session sit side by side, so you always know what you did and what comes next. Today's weather for your rowing spot, with wind, humidity and sunrise, is right there too.
