Ibis paint x stabilizer problems

I purchased a iPad last year so I could start creating more digital art even when I'm not at home, however I travel pretty often by bus or car and occasionally by train, why is the stabilizer so terrible in ibis paint x? Heck it's even shaky when I'm drawing with my iPad sitting on a stable desk/table.

I have it set to 100%, the same amount I have it set to via krita on my laptop, yet my lines are still shaky, I tried looking up tutorials online but there doesn't seem to be a solution.

Am I doing something wrong? I just wanna be able to create art when I'm traveling, it defeats the purpose of me having the iPad if I can't use it for the thing that I brought it for.

Can anyone help or offer an alternative free art app suggestion please?

I really hope krita creates a iPad version someday
