Yeah, the logarithm is pretty accurate for the most part. It all depends on the words you use. I think the stats are more geared towards people who journal, maybe, and want to see what their outlook for the day/week/month has been? But it's still interesting to look at it and see what the computer says my writing feels like.

And I can't comment on whether it would be worth it to pay since I'm not paying XD I think that kind of thing always depends on the individual, and what motivates them. But it's at least kept me writing this month!
