Hey there, glad you are liking the app. Lets see.
1) Yes, the poke/touch got a lot of modifications, i like the idea of putting a tweak setting, will add this to the next version since is something easy to do.
2) This is truly a major problem from the app, not your hardware. Right now i am trying to improve this, plus already added a bunch of new stuff.
In the future I want to create a way to record perfect loop animations, but it easier said than done.
