Probably not now, but I can sometimes write two or three stories a day, and then not write for three or four days. So, because the app sends your work, via email, to your subscribers, I would land up spamming them.
The other things were that payment was by readers subscribing to one personally, so if I took off a week or two, or if a changed topics, etc. it would in a way be dishonest, and I cannot commit to writing the same type of thing over and over again.
Also, the formatting isn't quite as nice as that on Medium - if you provide a link, it doesn't populated, and I find that annoying, because I always back up what I say with evidence.
That's about it.
However, I took a look at one of my sites that I didn't shut down, and one can post without it going out through email. I have to look at other things as well.
