Our testing team - 22 teachers from around the world - have begun to feed back. Their thoughts so far have been overwhelmingly positive.
(Don't forget these are not our friends and relations - these are ELT teachers we have met on Facebook and Twitter - so it's lovely to get good feedback from them.)
We're getting loads of great ideas for amendments to the basic app, and we're also getting a few bugs, of which we think Kate's impressive score for Part 4 is in the lead for most puzzling. Surely even teachers aren't that good?
Everything needs fixing before release, so we're working very hard at the moment.
