It is one of the few 'spell check' apps that actually works, and well. But i have a real problem with not being able to give color to the fonts and/or keys. All the other keyboard apps have this option. I can't believe you wouldn't have added this obvious detail to your options list! Your photo background option is ok, as far as it goes.. but expansion would be in your favor, AND your customers. If your app DOES have an option's list... where is it?? Am i just missing it?? Your 5 Stars wait!

I have survived three strokes which of them happened in the year of 2016. I lost my ability to speak. I lost my short term memory. I slowly gained a lot of my abilities back. I still have issues with being too wordy. This app is teaching me so many element to grammar. To me, Grammarly, delivers a superb product/services for commercial/resistance consumers. Thank you, Grammarly staff, for this well developed process of creating a more interesting conversation.

The application is good and spell check, grammar, and sentence structure can't be beat but the keyboard is not great. This is especially true when switching from Gboard which I have used for years. Forcing the use of the keyboard to get the spelling and other features is not great. I have a premium subscription for my desktop and won't renew because of this "feature". Microsoft is famous for their "forced use policy" which turns people off. I can't lower this 3 star because other feature great
