Good, but no new features or development in ages!
Decreasing my rating to 3 stars and updating this review, as there has been no further development on this app in a very long time. This is good app to really slow down and understand the freestyle stroke. However, development has stopped and nothing new has been added in a very long time. This makes me wonder about the future viability of the app if I were purchasing it today. More strokes could be added, breaststroke, backstroke, etc. Bring back the development, add features/strokes, will change rating to 5 stars.
