Has anybody tried using this?

Tried the app last night. Have to say I really liked it. Very easy to keep track of everything. No more getting a pen out to record subs. Very intuitive. Very simple to handle subs, plus if there is ever a problem with the score, you have a complete record of who scored what points to compare with the official book. Only one problem. Holding Itouch in the hand makes it hard to mirror 4 hits. Very minor problem.
