A really good app. Find myself coming back to it every few months to remind myself about the stuff I've forgotten, but should know.
Doesn't worth to buy it.. only one freestyle stroke for 25 riyals. unless they will add the other strokes
Doesn't install On nexus with latest android as per other comment
It contains one style only
Watch & think stroke through developing from beginner to intermediate swimmer!
Worth the money Good for checking form regularly and easy to use
