Good but plan fix

Good app but the only problem is that I have only about 20 seconds before it says there are no mistakes when clearly there are mistakes since it said so, I am on an iPhone 6s and I hope you can fix this soon.

Perfect Use

Grammarly helped me to use better punctuation, grammar and also words. Other autocorrect won't let you do the word that you want and they just underline it red, but once you add the word you added to your Personal Dictionary they let you write it without even underlining the word. Almost every autocorrect doesn't have that. Great work Grammarly!

can access passwords & credit card details

As much as I enjoy the Grammarly online version, I don’t feel comfortable using this app on my devices at all. Download and use of this app requires full keyboard access. This means ALL data typed on your device is sent to Grammarly developers, including bank account details, passwords, credit card information and even searches online. I’m not using this app as it’s not in the best interests of the user and could pose a potential security risk. Not happy, please make the online version available and bug free on iPad.
