★★★★☆Ann Fraser· Jun 1, 2026
I love this app on the phone because I can use the improvement my writing feature to clean my writing and grammar. I don't like this app on pc because this feature doesn't exist. Please add it back into the pc versions. I need it. Thank

Very subtle, but it works magic. It suggests full paragraph corrections with better wording and punctuation.
★★★★★Eran Hazelwood· Jun 11, 2026
Grammarly is so helpful. I especially enjoy how it checks the tone of your writing and can transform it to sound any way you want.

This app came standard on Samsung devices. It worked well then. It just fixed common problems. Now I have to install the app. It barely works. It will tell me to fix errors from hours ago. I'll type something at 10am in a note app. I'll fix that problem. At 5pm I'm using Facebook and Grammarly will tell me to fix the problem from 10am. I then go to type an email, it will still suggest the problem from 10am be fixed. Sometimes it suggests things from days ago be fixed. I'm not typing that message
★☆☆☆☆RJ. E Jones· Jun 4, 2026
The update with AI mode is unacceptable, as it takes over everything and has made me despise this product. I want the old version restored immediately. I did not request this AI mode nonsense. I would have rated this five stars, but with AI mode, it deserves only one. Stop following trends and listen to your users. This app is trash because they are professionals making millions, and you want us to start writing like I am literate. You cannot forget about centuries of writing properly.

I suggest making the apk simple and fast/straight forward. It should have an option for expanding if ever the user requested to. Because I notice the apk is a bit harder to use compared to other apk the only reason I used this is that I trust this apk compared to others. that's for my apk review

For all the money we spend on this thing it should be running flawlessly and yet glitches and malfunctions all around. Uninstall, reinstall, new issues at every turn. Won't be paying another 150 bucks for this nonsense if things do not begin to run smoothly ASAP! And for GOD’s sake what's the issue with syncing the website and app??? Where are my docs? Why can't we make folders? It's 2026! I'm not submitting HIT Say.
