Best grammar application out there

Really like this application helps me correct my grammar so the grammar police online doesn’t come for me which I don’t care anyway the application comes to the correct words and underline them with a box, so you can correct them without figuring out where the word is at in the sentences. Thank you for this application you did an awesome amazing job the application is very easy to us. Translate and much more one of the best application out there. I highly recommended this to anyone.

Checks grammar, but poor app layout.

This app does have good grammar checking capabilities! (For a price, and that’s price is unfortunately a subscription.)

HOWEVER. The app layout is miserable, and simplistic to the point of difficulty. The app forces you to constantly jump back and forth between proofreading and writing mode, and every time you do, it rechecks the entire document for errors. This means every time you have to make a small edit or correct a word differently than what the app suggests, you have to filter BACK through the 20 other changes you already dismissed. Also, there’s no way to “teach” the spellcheck names, so prepare to constantly be battling it for character names or fictional places.

Great app but one problem

I would prefer this app over Grammarly because it actually corrects everything and not just the words that are wrong. The only thing that I don’t like about this app is that when you type out everything and want to paste it on Wattpad, it doesn’t work. I’ve tried on different apps but it only doesn’t work on Wattpad. Overall, this app is really good but I wold like it a lot more if I could pate my writing on Wattpad.

Dear User,
Thanks for your review. I am glad to see that you like the app. Regarding the issue you mention, it might sound more related to that app than to ProWriting. Please contact support at with further details about the expected behaviour with paste. All the best.
