Yep I think also that they are quite good for what they are.
Sort of I lost the source code of Shamisen Player though and it includes a prominent broken weblink.
Shamisen Player Pro featuring all tunings and a glossary of japanese terms is the version I can and would recommend to be checked out 
(can be found on google play)
As it happens I am about to release another completely unrelated app where I also managed to include a drumboard with taikos and a shamisen sound in a simple game there.
Unfortunately though I hardly have the time and energy to do anything much besides the 12 hour no vacation taxi job so the overall app related progress as for learning and doing has been and is far out painfully slow.
So therefore I won’t be able to help out anytime soon as for example Calvin’s good suggestions or any comprehensive bachido app would include several programming aspects I am so far not at all familiar with.
Overall and that said as for me, guess the slow if any progress of a bachido app or even a concept for it could also have to do with how great the website already is.
And I am not even a fan of apps that offer what can just as well be done on a website.
So with the awesome site already there I guess generally I am also not even yearning specifically for a bachido app unless it would offer something original and cool that wouldn’t work well or at all in website form.
Generally like making an app out of the whole website could just be a lot of work for sort of nothing new.
Yeah also to not write even more unhelpful in the matter paragraphs all I have more to say at this time actually and sincerely is Happy Easter
