The new hover over options sucks!! This new non-keyboard feature is the worst!! It never works! It constantly says nothing is wrong while I purposely made errors ro see it's accuracy!! So VERY dispointing! I pay for the premium and this feature absolutely doesn't work! Take for example this message, grammar lyrics says it great!! Like what the heck!!

Amazing app. I use the desktop app all the time and I was curious to see if the mobile version would be as good. The 30 minute suspend feature is what makes this app gold. Otherwise, the grammarly bubble can be a bit invasive. For the most part, it plays nice with most other apps as well. A great additional spell check tool for mobile.

I love that it gives suggestions on everything you type, from texts to letters and even notes. Very helpful if you're not very good with grammar and punctuation place meant. It also gives options to improve what you have written. It'll tell what kind of tone your message is giving. Very, very helpful. I haven't had any issues with it, yet
