Its crash frequency unnerves me

I like the way the app works and it helped me write more and better, even if it is a bit expensive for what it does and for how it works. There are many ways in which it could be improved (for one, ability to save what you are writing before you finished writing, just by pressing a key). But - sadly - what is really bad is that it is really wasting my time, when it frequently and unexplicably it crashes and trashes all that I have written in the past 10 mintes or so. CAN YOU GUYS FIX THIS? I NORMALLY DON’T WRITE REVIEWS BUT THIS APP REALLY FORCED ME TO.
