Good but needs an update

Ive had this app for a while now, and up until the last few weeks, it had worked great. I think it needs an update to fix some bugs and itll be great again.
When I have tried to use it recently, the screen is very off and doesnt stay still even when you arent moving the phone. It wont calibrate so nothing is where it says it is.
When all of this is fixed, Ill come back and change my review if possible. Im more or less trying to get the creators attention so they can fix these issues and the app can properly be used again on my phone!
