It's an okay app; it does what it says. I've been using it for a couple of weeks; the unpaid version works well. Sometimes if you are typing up a lot, it can lag a bit. But the main problem I found was that the assistant features get disabled like all the time and you have to go to the settings and turn them on often for them to work. Also, the widget sometimes glitches. Anyway, I stopped using it today because it isn't convenient anymore.

It just took forever to type something because the keyboard just is not very convenient with its layout, it seems to analyze as your typing. Just let me type it out and analyze it after. I've been using SwiftKey for years and this just felt like a step back. I was assuming it would work like Google keyboard or SwiftKey, but just enhance it. Definitely needs fixing.

I had enough. The app just keeps glitching whenever I open it. I still used it despite that and it stuck and froze and when I tried to re-open the app it lost everything I wrote in there. Everything gone. it's not even the first time... it kept happening day after day. It can't even save a document properly. I quit. I lost so much of my time like this.
