Regatta is my favorite rowing app. The instructors are great... energetic, clear, and do a fantastic job demonstrating the rowing technique and pacing. They also have rowing lessons for different levels (beginner, intermediate, advanced), different amounts of time (20, 30, 45 minutes) and purposes (cardio only, + strength training, toning, stretching, etc.). You can filter your selections by any parameter so picking a class is real easy. Outstanding. They say there will be live classes, but they have not instituted this yet; but, in fairness, we are in the middle of a health crisis. The ONLY reason I need to take a star, that makes me unhappy, is the application's inability to sync with other applications including Concept2's ErgData app. This is a major shortcoming as my other go to rowing application (Live Rowing) automatically syncs with Apple Health, Concept2's online log, and Strava. I also note Asensei also links to ErgData. I chose Regatta as the far better value! I wrote to Regatta and I was very pleased to get a reply that in an upcoming version syncing will be incorporated. When that happens, this reviewer will change this review to an even better one, and make it a perfect "5" review. So, if you feel that syncing to third-party apps is a major priority for now, hold off on Regatta for now. But, if you can live without syncing for a while, Regatta is a great value and experience!
