Now that I’ve brushed up on some things, I may not let opponents get away with as much anymore! Great idea and format, so thank you, I’m going to tell everyone I know about it!

I have been working my way through iKnowTennis! app and really enjoy it – I’m kind of a nerd about rules so I think it’s a lot of fun.

iKnowTennis! is a must have app for all tennis players. A great resource for all tennis rules and regulations. The quiz section is a great way to test your knowledge [and pass time waiting for your doubles partner to show up]!
