Neither do I - Android all the way!
I use Rec Forge 2 Pro. The UI to edit is not super intuitive to start, but once you have it it's easy. The developer is very responsive if you email with issues or questions, and has some additional info online.
Lower the game volume in your video editor and record (preferably) with multiple microphones. You can use Audacity or if your microphone is mono, using an Android phone to record is also fine. Then mix the tracks together in your editor of choice. If you are close to eachother, make sure there is no echo, if you need it, lower your recording volume, amplify it in audacity and reduce the noise. Use your Blue Yeti, and if you don't have more microphones, use your phone's built-in or plug in headphones with a mic (EarPods have a great Mic) Here are some good audio recorders for Android: https://play.google.com/store/apps/details?id=dje073.android.modernrecforgepro&hl=hu https://play.google.com/store/apps/details?id=com.andrwq.recorder I don't mess with iPhones, I don't know how to get the recorded file off of it, and they are limited.
I second cyalith on rec forge... I use that app to record on a Nexus 6P.
There's a newer version - Rec Forge II Pro - that's got a more updated UI and works better on phones running marshmallow.
It is slightly non-obvious how to edit in this app in the beginning, so I recommend recording a couple tracks you don't care about and giving it a shot. Otherwise, it's a great app and significantly better than most of the free ones. I tried several.
One of the biggest hurdles to recording on the phone is finding the sweet spot in terms of picking up everything you want to pick up, without getting too much noise from breathing, etc, and keeping it there. It's not rocket science, obviously, but it's easy to drift away or too close to the mic if you're uh, less focused.
Have fun!
