Overall great

Great overall! I tried this app because the privacy policy is less invasive than Grammarly is.

It does a good job, and I love that it explains why you should change something.

It’s much better than the free version of Grammarly, and in my experience catches most of the same stuff as the paid version. Likewise, it’s 100x better than outlook/Microsoft Office’s grammar checking.

There are a few things I’d like to see more of / suggestions, but I am super happy with the app so far and paid for the subscription. As a dyslexic who never learned grammar, this is an invaluable tool.

The biggest suggestion/request would be to have a desktop app, a website, or a browser / outlook extension. I use this for work emails and would love to more easily be able to access it at work. I don’t mind paying the pro version, but it’s a bummer I can’t access it from my desktop like you can with some competing apps.

Other things, I think it would be cool if there was an option to click on suggestions and maybe link to more information or just explain in more detail. For example, one sentence in this review it says ‘long subordinate clause’ but I don’t even know what that means LOL. It’d be awesome if I could get more details right from the app.

Other suggestions would be for detecting tone and a tool to summarize things. It would also be cool to set preferences for formal or informal writings/words, simple to understand/low reading level, etc.

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.

Suggestion for improvement

This is a great app. Could we see a future update we’re this app can be added to the keyboard of texting messages on iPhones. so we don’t have to keep cutting and pasting every time to see corrections
This will make everything faster and more efficient. Also adding it to computers on the email dash to check the email while writing the email. Also compatible with word docs for corrections instead of cutting and pasting every time. This could be time consuming to cut and paste just see corrections. The generation now days is a fast moving pace and I believe this app can go further with these simple up grade.
