The monthly fee (if you have a Hydrow) is $38 per month. This allows you to view rowing workouts right to the touch screen as well as keep track of various metrics. If you don’t own a Hydrow but want to still use the app on your smartphone, the cost is $19.99. Besides rowing, the Hydrow app also offers things like pilates, yoga, and strength training. This could be a good option for someone looking to ditch their gym membership and ease into doing home workouts.
