I use a Lanikai SMP-C uke, which is concert sized, so it's a bit bigger. Which suits my fat sausage fingers (
) a bit better than the soprano CK-S that my wife has. The tuning is exactly the same. I put a Kremona UK-1 pickup on it, and I plug that into an iRig Pro interface to connect it up to my iPad. That setup works great with the Uke stuff in Yousician. If I'm playing with headphones on, I run JamUp Pro with the acoustic expansion pack, in background mode, so I can hear myself.
And, yes, all that setup is far more professional sounding than my (lack of!) talent requires.
But it does sound good!
