Great app if you are into visualizing. Provides a bunch of different angles and stroke rate speeds so you can slow it down or speed it up depending on what youre looking for. Fantastically realistic graphics. Some suggestions: Allow Ms Swinger to also be a male! I cant relate to a female swinger and dont want to visualize a female when Im a male lol. Allow Ms Swinger to have a stroke rate of 100 +. I wanna see her sprint! Allow for full screen/get rid of the swim smooth logo and text at the top. I just want to see the swimmer sometimes with no distractions. Make the two swimmers in sync so when ms swinger is at the top of her stroke, mr smooth is at the exact same place when u switch to him. All in all, great app and worth the price. Thanks.
