Glad to hear that. It should be noted that the UK voice will also probably be chosen by parents in other Commonwealth countries besides the UK because of the way the letter "Z" is pronounced "Zed", not "Zee".
I really love to make it better for UK people. This is small market compared to the US but as you can see in my post, small market (like France) can be profitable as well. By the way, I've also have a lot of request to use a UK voice for Montessori Crosswords and that's something I want to do as well (in this app it is a recorded voice)
