One of the MOST innovative apps

I know a lot of people did not rate this app 5 stars because it sometimes has weird glitches. Nothing that an app update didn’t fix. I use the Grammarly keyboard everyday at least once a day when I text. I initially started using Grammarly because texting is the main way my friends and family communicate with me. I have ADHD which makes it hard for me to word my thoughts, stories, questions, etc. verbally. It is even more difficult to convey my thoughts in a text message conversation because I simply just type the quick thoughts / ideas as soon as it pops in my head. Not realizing that my texts didn’t match my intended tone. Or my texts confused people bc I have difficulty shortening my thoughts. With the Grammarly keyboard I can still type out my text quickly and then i just scan it after to check for any grammar errors. It forces me to reread my texts as I correct the grammar too. Finally the tone detector adds the extra awareness to how my text is perceived. Over time I feel my grammar has improved as well as the way I express my emotions in writing. Please check out their website and other tools as well! They all work well together. You will take your grammar and writing to new levels with grammarly.

full of bugs, that support won't address

I have written and in the process of editing/proofreading it, so i thought grammarly would be a good choice, well it is BUT , my book is over 70k words, but you can not import that file, since grammarly has limitations on the size, so i can only edit 8k words at a time, and God forbid you are trying to edit on an ipad (have ipad pro 11, 4th gen), you will be left with a 2*2 inch of working space to read, a lot of time it will stop saving, because it saves only online (God forbid of local save) so unless you copy and paste to "pages" you will loose all the edits that you do or have done. the "undo" is a disaster, suggestion that you choose to ignore temporarily stay in the way, suggestions will be hidden behind the keyboard, so you have to close the keyboard many times to access it, tons of bugs, and when i addressed it to their support, they would ignore what i say, and suggest things like "check your internet connection" , even though i said my connection is fine, and as per this typing i have recorded the issue proving that my connection is fine, but no one listens. tons of bugs and limitations. You would think as much as grammarly is advertised they would listen to constructive criticism with bugs that deserve fixing, but no, they ask for my file, MY BOOK, so no am not sending the file since it is irrelevant.
I would love if that App works without the glitches and bugs, but it is and sadly enough, their support is not as supportive.

Suggestion: when a correction is suggested it would be nice if the reason/rule of grammar is quoted so we’ll learn at the same time. Maybe that's a premium service idk but that way you actually learn versus just blindly accepting correction and sometime not knowing exactly what or why the grammatical error is you’re making. IJS....Also I was proofreading my answers to a test and out of four questions asked one was supposed to have a grammar error. I typed all four sentences exactly into Grammarly but it didn't indicate any errors/corrections needed. Yet of course according to the test you were to identify the one that was wrong. So I hope I chose the right answer based on their criteria. So I don't know what's right the test or Grammarly. The test results don't tell you which were right answer not wrong; if they consider yours wrong, they just say it's wrong & give you the calculated score. Can somethings really be that subjective? I'm going to try and research the questions via another source and see if I can get different result. If that's the case then I may have an appeal to the test results scoring based in those questions that possibly could have more than one way for an answer to be considered correct.! Perhaps they need to update or clarify questions so there are no options for a correct answer. I'm sure there are plenty in this review because I ignored all suggestions.
