I'm looking to re-invigorate my practicing enthusiasm with an iPad and the Tonebridge app to fire up my interest. The sound effects that Tonebridge uses to quasi-replicate famous guitarists' tones are good enough to have some fun with. Questions: Would the iPad 9.7" be just as useful as the increased real estate of the 12.9" iPad Pro? Is one better than the other for strictly guitar practice? I'll be plugging in my Nocaster and Fender Pawnshop '51 via an Apogee Jam guitar interface for iPad. Is Tonebridge a good app to jam along with my favorite .mp3s? Would you guys recommend a different app? Not too many reviews of Tonebridge online, even though it was released in summer 2016. I've heard that iOS is better for musicians and guitarists due to lower latency and that Android is significantly lacking. This is supposedly due to Android audio APIs being based around Java and aren't great for reliability and some of the general rules of Java coding having to go out the window Android. One API for instance, can tend to break if you don't add in a delay of 30-40ms; which is obviously a crap solution.
