Lyricpad 2

Long time user of Lyricpad 2, and absolutely have loved it.
I am trying to. Clone a backup tablet in case . . .
I purchased lyricpad 3 but I prefer 2
Downloaded a trial version but l need to purchase the full version please.
I will gladly pay, l don't want a refund on 3. I plan on implementing it eventually.
Can you advise/send link for purchase?
Use my email please.
Thanks in advance.

I just recently have tried this emailed Dan the inventor and he says there's no way because Play Store will not allow it due to security problems with the software. I also downloaded the free version but there's no way to update it . I'm not really a fan of version three but I did get it installed on my phone finally and I think I can use it but I've got the old version on my tablet so I'm going to stick with that as long as I can

I just got it to work with ES file Explorer check you tube videos file transfer with bluetooth.Im so happy
