I run biab windoze 2019 and have an ios (ipad/iphone) environment for playing out

I have tried the bb2go ios app a few times since it came out.
I do not use it.
There are other apps out there that I find more useful.

So, I use .wav files for playing on my phone/tablet
You can generate these (or mp3's) and then transfer them to an appropriate iphone app.
If you use Icloud you can transfer them there.

For apps there are many wav/mp3 players starting with Itunes.
For more performance/practicing apps I use Anytune Pro. Lots of good features (looping, speed adjustment, set lists).
There are many others.

Hope this helps
