The app is good but I have 2 suggestions. 1. The icon on the mobile app blocks the view on the screen due to small size. Kindly make it compatible. 2. Grammarly says "Due to security reasons, the data is only available on this device". It is comfortable to sync across devices so that I can access from anywhere. If editors like Google Docs, Google Sheets, Gmail Drafts etc can sync across devices without any security issues, why can't grammarly. Kindly fix these issues ASAP and keep growing.

I've been using Grammarly for almost six months now and it really helps me improve my writing, especially with grammar and spelling. I like how it catches small mistakes that I sometimes overlook. It’s also great for checking tone and clarity. Very useful whether for school, work, or just everyday writing. Highly recommended for anyone who wants to write more confidently and professionally. 📝✨🤗🤍

The app is good (I used it on computer and mobile) but It's not perfect. One: It would stop working and I'd have to uninstall then reinstall for it to work again—on computer, the download version doesn't work for me and the extension glitches like mobile. Two: The Grammerly icon can get stuck on the screen, and you'd have to restart the app (uninstall) or reset the device (only mobile). (I probably forgot other issues but other than the two things above, it's a pretty good writing app!)
