App closes on its own

Omg!   You have to fix this.  It’s so annoying!  I use your app for a few minutes and then it shuts down on me.  I open it and it shuts down after just a few seconds.  It’s unusable.  The only it works is by shutting off my phone completely.  But I shouldn’t have to do that all the time.  I love your app.  It’s the best!  PLEASE FIX THIS!!!!!
