Oops, just noticed your link.
I suppose I am so pleased with myself only just having discovered it that I got carried away.
In fact, I have known about it for a long time but tried to download it to the computer. Of course it didn’t work being Android based, and I only recently realised that the little Asus tablet I carry around with me is too.
I do report on it though, having also just discovered how to make the tablet not change my French text, and for one particular routier gave them a right roasting.
