I decided to download the app again. It still isn't amazing. I really wish there was a way to safe "mistakes" as intentional, like when I use unique nicknames. It always wants to correct things like Ly (my nickname for Lyra). Also, the thing where you select the text and it instantly takes you to the app to be corrected doesn't work. It just takes you to the app without the text.

Normally I love the app, it might not catch all of my mistakes, but it does catch a large portion of them. However, as of recently the app has been bugging out. It'll do the grammar portion, but when it comes to Synonyms section my entire content is a grey screen. The suggestions still pop up, but what's the point if I can't see my writing. I've tried to uninstall it hoping it would fix it but it didn't, I pay for this app so can someone get back to me ASAP!!!!!!!!!!

Please make sure to update the app to the latest version. The issue with the Synonyms is currently fixed. My apologies for the inconvenience, it was a rare bug affecting some texts. Contact support if you need further assistance. I hope you can consider updating your review accordingly. Thanks.

Highly recommended. This is the one I need. Uncomplicated and fast. It has a clear enough layout that one can instantly get started and just select, copy and paste an email (or long WhatsApp text) into it for checking prior to sending. Just copy and paste it back into the email window first. Or just write it in this proofreader to begin with and copy+paste it into your email window. You're done!
