This app has gone downhill. I paid for premium, which was a big mistake. It censors way too much when you're doing creative writing and want suggestions for particular scenes, and treats adults like children. If you want a generic spell check, it's good. But sometimes its grammar is incorrect, and it glitches very often, and flags sentences that are perfectly fine. Definitely overpriced for the heavy censorship and inaccurate suggestions and corrections. If it improves, I will change my rating.

I have never enjoyed the value of the App not found anywhere else. I am using the free version because I just have it to avoid sounding less foolish sometimes. I really wish that they had an affordable subscription to cater to people who just appreciate them. Strictly personal use. I would consider buying into it if it was reasonable for residential use. 5/5 For the rating is well earned.

so idk if it was an update or whatnot, but this used to be great, but now it doesn't correct everything. it misses small mistakes, and the floating icon doesn't even always work. you can even see it here as I have typed this as it still misses certain things. I have had to reinstall the app twice to get it working correctly again but it always persists.
