We'll admit, it can be super annoying when somebody doesn't know 'their' from 'there' or 'your' from 'you're'.

And if you're just fed up with your mates sending you messages filled with errors, your dreams have now been answered.

A new app has just been launched that will let you correct any text message sent to you with grammar mistakes in it.

Called Grammar Snob, the iOS 10 sticker app will make you feel like a school teacher as you can scribble in red ink and point out any grammatical errors in a text or email.

However, you'll have to pay €1 for it (boo), but it means you might soon be able to live without rolling your eyes up to heaven at every Tinder bio you read.
